Dietary Polyphenols, Microbiome, and Multiple Sclerosis: From Molecular Anti-Inflammatory and Neuroprotective Mechanisms to Clinical Evidence.
Multiple sclerosis (MS) is a multifactorial, immune-mediated disease caused by complex gene-environment interactions. Dietary factors modulating the inflammatory status through the control of the metabolic and inflammatory pathways and the composition of commensal gut microbiota, are among the main environmental factors involved in the pathogenesis of MS. There is no etiological therapy for MS and the drugs currently used, often accompanied by major side effects, are represented by immunomodulatory substances capable of modifying the course of the disease. For this reason, nowadays, more attention is paid to alternative therapies with natural substances with anti-inflammatory and antioxidant effects, as adjuvants of classical therapies. Among natural substances with beneficial effects on human health, polyphenols are assuming an increasing interest due to their powerful antioxidant, anti-inflammatory, and neuroprotective effects. Beneficial properties of polyphenols on the CNS are achieved through direct effects depending on their ability to cross the blood-brain barrier and indirect effects exerted in part via interaction with the microbiota. The aim of this review is to examine the literature about the molecular mechanism underlying the protective effects of polyphenols in MS achieved by experiments conducted in vitro and in animal models of the disease. Significant data have been accumulated for resveratrol, curcumin, luteolin, quercetin, and hydroxytyrosol, and therefore we will focus on the results obtained with these polyphenols. Clinical evidence for the use of polyphenols as adjuvant therapy in MS is restricted to a smaller number of substances, mainly curcumin and epigallocatechin gallate. In the last part of the review, a clinical trial studying the effects of these polyphenols in MS patients will also be revised.

Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments. Regarding the untouched area, Hero 642 system showed 22.78% ± 6.42% and Reciproc R40 34.35% ± 8.52%. Neither instrument achieved complete cross-sectional root canal debridement. Hero 642 system rotary taper 0.02 instruments achieved significant greater wall contact perimeter and area compared to reciprocate the Reciproc R40 taper 0.06 instrument..

Targeting Nuclear Factor-Kappa B Signaling Pathway by Curcumin: Implications for the Treatment of Multiple Sclerosis.
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system, which involves an auto-immune mechanism that leads to perivascular demyelination. The role of nuclear factor-kappa B (NF-κB) signaling pathway in the pathogenesis of MS has been suggested by genome-wide association studies. Therefore, strategies targeting this pathway could be potentially beneficial. Curcumin is the active component of turmeric and a phenolic phytochemical. This phytochemical has anti-inflammatory properties and has been shown by multiple studies to downregulate NF-κB and its downstream gene targets including cyclooxygenase-2, tumor necrosis factor-α, interleukin-1, and interleukin-6. This review discusses the modulatory effects of curcumin on the NF-κB signaling pathway and its downstream effectors, and the therapeutic implications of this modulation on MS.

Curcumin as a therapeutic candidate for multiple sclerosis: Molecular mechanisms and targets.
Multiple sclerosis (MS) is a disease that has shown a considerable increase in prevalence in recent centuries. Current knowledge about its etiology is incomplete, and therefore it cannot be managed optimally utilizing targeted therapeutic regimens at each stage of the disease. MS progresses in different stages, beginning with a cascade of inflammation. The pivotal spark to initiate this cascade seems to be the migration of Th17 into the central nervous system across the blood-brain barrier (BBB) through the disrupted tight junctions. Coupling of interleukin (IL)-17 and IL-22 to their receptors in the BBB layer facilitates this migration. Subsequently, axon degeneration and the various manifestations of nerve-muscle disorders appear. Curcumin, a major component of turmeric, is derived from Curcuma longa, which belongs to the Zingiberaceae family. Numerous properties of curcumin have been identified recently, some of which can be effective in the treatment of MS, particularly the anti-inflammatory properties via inhibition of secretion of proinflammatory cytokines. In this paper, we will review the various properties and key effects of curcumin for the treatment of MS.

Curcumin in Autoimmune and Rheumatic Diseases.
Over recent decades, many clinical trials on curcumin supplementation have been conducted on various autoimmune diseases including osteoarthritis, type 2 diabetes, and ulcerative colitis patients. This review attempts to summarize the highlights from these clinical trials. The efficacy of curcumin either alone or in conjunction with existing treatment was evaluated. Sixteen clinical trials have been conducted in osteoarthritis, 14 of which yielded significant improvements in multiple disease parameters. Eight trials have been conducted in type 2 diabetes, all yielding significant improvement in clinical or laboratory outcomes. Three trials were in ulcerative colitis, two of which yielded significant improvement in at least one clinical outcome. Additionally, two clinical trials on rheumatoid arthritis, one clinical trial on lupus nephritis, and two clinical trials on multiple sclerosis resulted in inconclusive results. Longer duration, larger cohort size, and multiple dosage arm trials are warranted to establish the long term benefits of curcumin supplementation. Multiple mechanisms of action of curcumin on these diseases have been researched, including the modulation of the eicosanoid pathway towards a more anti-inflammatory pathway, and the modulation of serum lipid levels towards a favorable profile. Overall, curcumin supplementation emerges as an effective therapeutic agent with minimal-to-no side effects, which can be added in conjunction to current standard of care.

Benefits of curcumin in brain disorders.
Curcumin is widely consumed in Asia either as turmeric directly or as one of the culinary ingredients in food recipes. The benefits of curcumin in different organ systems have been reported extensively in several neurological diseases and cancer. Curcumin has got its global recognition because of its strong antioxidant, anti-inflammatory, anti-cancer, and antimicrobial activities. Additionally, it is used in diabetes and arthritis as well as in hepatic, renal, and cardiovascular diseases. Recently, there is growing attention on usage of curcumin to prevent or delay the onset of neurodegenerative diseases. This review summarizes available data from several recent studies on curcumin in various neurological diseases such as Alzheimer's disease, Parkinson's disease, Multiple Sclerosis, Huntington's disease, Prions disease, stroke, Down's syndrome, autism, Amyotrophic lateral sclerosis, anxiety, depression, and aging. Recent advancements toward increasing the therapeutic efficacy of curcuma/curcumin formulation and the novel delivery strategies employed to overcome its minimal bioavailability and toxicity studies have also been discussed. This review also summarizes the ongoing clinical trials on curcumin for different neurodegenerative diseases and patent details of curcuma/curcumin in India.

Therapeutic potential of curcumin for multiple sclerosis.
Multiple sclerosis (MS) is a chronic autoimmune inflammatory disease of the central nervous system (CNS), characterized by demyelination, neuronal injury, and breaching of the blood-brain barrier (BBB). Epidemiological studies have shown that immunological, genetic, and environmental factors contribute to the progression and development of MS. T helper 17 (Th17) cells are crucial immunological participant in the pathophysiology of MS. The aberrant production of IL-17 and IL-22 by Th17 cells crosses BBB promotes its disruption and interferes with transmission of nerve signals through activation of neuroinflammation in the CNS. These inflammatory responses promote demyelination through transcriptional activation of signal transducers and activators of transcription-1 (STAT-1), nuclear factor kappa-B (NF-κB), matrix metalloproteinases (MMPs), interferon ϒ (IFNϒ), and Src homology region 2 domain-containing phosphatase-1 (SHP-1). B cells also contribute to disease progression through abnormal regulation of antibodies, cytokines, and antigen presentation. Additionally, oxidative stress has been known as a causative agent for the MS. Curcumin is a hydrophobic yellowish diphenolic component of turmeric, which can interact and modulate multiple cell signaling pathways and prevent the development of various autoimmune neurological diseases including MS. Studies have reported curcumin as a potent anti-inflammatory, antioxidant agent that could modulate cell cycle regulatory proteins, enzymes, cytokines, and transcription factors in CNS-related disorders including MS. The current study summarizes the reported knowledge on therapeutic potential of curcumin against MS, with future indication as neuroprotective and neuropharmacological drug.

Use of Vitamins and Dietary Supplements by Patients With Multiple Sclerosis: A Review.
Surveys of patients with multiple sclerosis report that most are interested in modifying their diet and using supplements to potentially reduce the severity and symptoms of the disease. This review provides an updated overview of the current state of evidence for the role that vitamins and dietary supplements play in multiple sclerosis and its animal models, with an emphasis on recent studies, and addresses biological plausibility and safety issues.. Several vitamins and dietary supplements have been recently explored both in animal models and by patients with multiple sclerosis. Most human trials have been small or nonblinded, limiting their generalizability. Biotin and vitamin D are currently being tested in large randomized clinical trials. Smaller trials are ongoing or planned for other supplements such as lipoic acid and probiotics. The results of these studies may help guide clinical recommendations.. At the present time, the only vitamin with sufficient evidence to support routine supplementation for patients with multiple sclerosis is vitamin D. Vitamin deficiencies should be avoided. It is important for clinicians to know which supplements their patients are taking and to educate patients on any known efficacy data, along with any potential medication interactions and adverse effects of individual supplements. Given that dietary supplements and vitamins are not subject to the same regulatory oversight as prescription pharmaceuticals in the United States, it is recommended that vitamins and supplements be purchased from reputable manufacturers with the United States Pharmacopeia designation.

Curcumin has bright prospects for the treatment of multiple sclerosis.
Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease of the central nervous system (CNS). It is associated with a variety of pathophysiological features, including breakdown of the blood-brain barrier (BBB), autoimmune attack, injury of axons and myelin sheaths. Th17 cells are considered as a key immunological player for the pathophysiological process of MS. Neuroprotective approaches work best prior to the initiation of damage, suggesting that some safe and effective prophylaxis would be highly desirable. Curcumin, a dietary spice from turmeric, has outstanding anti-inflammation and neuroprotective effects. Herein, we review key features of curcumin involved biology, pharmacology, and medicinal chemistry and discuss its potential relevance to pathophysiological progress of MS.

Unprecedented community containment measures were taken following the recent outbreak of COVID-19 in Italy. The aim of the study was to explore the self-reported future compliance of citizens with such measures and its relationship with potentially impactful psychological variables.. An online survey was completed by 931 people (18-76 years) distributed across the Italian territory. In addition to demographics, five dimensions were measured: self-reported compliance with containment measures over time (today, at 7, 14, 30, 60, 90, and 180 days from now) at three hypothetical risk levels (10, 50, 90% of likelihood of contracting the COVID-19), perceived risk, generalized anxiety, intolerance of uncertainty, and relevance of several psychological needs whose satisfaction is currently precluded.. The duration of containment measures plays a crucial role in tackling the spread of the disease as people will be less compliant over time. Psychological needs of citizens impacting on the compliance should be taken into account when planning an easing of the lockdown, along with interventions for protecting vulnerable groups from mental distress.. La apendicitis aguda (AA) es la urgencia quirúrgica abdominal más frecuente. No encontramos estudios específicos que evalúen el impacto de la pandemia causada por el coronavirus 2 (SARS-Cov-2) sobre la AA y su tratamiento quirúrgico. Analizamos la influencia de esta nueva patología sobre la AA.. Estudio observacional retrospectivo en pacientes intervenidos por AA desde enero hasta abril de 2020. Fueron clasificados según el momento de la apendicectomía, antes de la declaración del estado de alarma (Pre-COVID19) y después de la declaración del estado de alarma (Post-COVID19) en España. Se evaluaron variables demográficas, duración de la sintomatología, tipo de apendicitis, tiempo quirúrgico, estancia hospitalaria y complicaciones postoperatorias.. La pandemia por SARS-Cov-2 influye en el momento de diagnóstico de la apendicitis, así como en su grado de evolución y estancia hospitalaria. La peritonitis fue lo más frecuentemente observado. Una sospecha y orientación clínica más temprana, es necesaria para evitar un manejo inadecuado de este trastorno quirúrgico común.. The primary outcome is improvement in PaO. Findings will provide timely information on the safety, efficacy, and optimal dosing of t-PA to treat moderate/severe COVID-19-induced ARDS, which can be rapidly adapted to a phase III trial (NCT04357730; FDA IND 149634).. None.. The gut barrier is crucial in cirrhosis in preventing infection-causing bacteria that normally live in the gut from accessing the liver and other organs via the bloodstream. Herein, we characterised gut inflammation by measuring different markers in stool samples from patients at different stages of cirrhosis and comparing this to healthy people. These markers, when compared with equivalent markers usually measured in blood, were found to be very different in pattern and absolute levels, suggesting that there is significant gut inflammation in cirrhosis related to different immune system pathways to that seen outside of the gut. This provides new insights into gut-specific immune disturbances that predispose to complications of cirrhosis, and emphasises that a better understanding of the gut-liver axis is necessary to develop better targeted therapies.. La surveillance de l’intervalle QT a suscité beaucoup d’intérêt durant la pandémie de la COVID-19 en raison de l’utilisation de médicaments prolongeant l’intervalle QT et les préoccupations quant à la transmission virale par les électrocardiogrammes (ECG) en série. Nous avons posé l’hypothèse que la surveillance en continu de l’intervalle QT par télémétrie était associée à une meilleure détection des épisodes de prolongation de l’intervalle QT.. Nous avons introduit la télémétrie cardiaque en continu (TCC) à l’aide d’un algorithme de surveillance automatisée de l’intervalle QT dans nos unités de COVID-19. Les mesures automatisées quotidiennes de l’intervalle QT corrigé (auto-QTc) en fonction de la fréquence cardiaque maximale ont été enregistrées. Nous avons comparé la proportion des épisodes de prolongation marquée de l’intervalle QTc (QTc long), définie par un intervalle QTc ≥ 500 ms, chez les patients montrant une suspicion de COVID-19 ou ayant la COVID-19 qui avaient été admis avant et après la mise en place de la TCC (groupe témoin. La surveillance en continu de l’intervalle QT est supérieure à la norme de soins dans la détection des épisodes de QTc long et exige peu d’ECG. La réponse clinique aux épisodes de QTc long est sous-optimale.. Exposure to a model wildfire air pollution source modifies cardiovascular responses to HC challenge, suggesting air pollution sensitizes the body to systemic triggers.. Though the majority of HIV-infected adults who were on HAART had shown viral suppression, the rate of suppression was sub-optimal according to the UNAIDS 90-90-90 target to help end the AIDS pandemic by 2020. Nonetheless, the rate of immunological recovery in the study cohort was low. Hence, early initiation of HAART should be strengthened to achieve good virological suppression and immunological recovery.. Dust in Egyptian laying hen houses contains high concentrations of microorganisms and endotoxins, which might impair the health of birds and farmers when inhaled. Furthermore, laying hens in Egypt seem to be a reservoir for ESBL-producing Enterobacteriaceae. Thus, farmers are at risk of exposure to ESBL-producing bacteria, and colonized hens might transmit these bacteria into the food chain.. The lack of significant differences in the absolute changes and relative ratios of injury and repair biomarkers by contrast-associated AKI status suggests that the majority of mild contrast-associated AKI cases may be driven by hemodynamic changes at the kidney.. Most comparisons for different outcomes are based on very few studies, mostly low-powered, with an overall low CoE. Thus, the available evidence is considered insufficient to either support or refute CH effectiveness or to recommend one ICM over another. Therefore, further well-designed, larger RCTs are required.. PROSPERO database Identifier: CRD42016041953.. Untouched root canal at cross-section perimeter, the Hero 642 system showed 41.44% ± 5.62% and Reciproc R40 58.67% ± 12.39% without contact with instruments.

ProspeCtive study to evaluate efficacy, safety and tOlerability of dietary supplemeNT of Curcumin (BCM95) in subjects with Active relapsing MultIple Sclerosis treated with subcutaNeous Interferon beta 1a 44 mcg TIW (CONTAIN): A randomized, controlled tria
multiple sclerosis (MS) is a complex disease sustained by several pathogenic mechanisms. As such, combination therapy strategies, targeting a range of disease mechanisms, might represent the ideal therapeutic approach. Here we investigated the efficacy of curcumin, a naturally occurring poly-phenolic phytochemical with potent anti-inflammatory and antioxidant properties, in subjects under treatment with IFN β-1a, to test the effects of this combination therapy on clinical and MRI parameters of inflammation and neurodegeneration in relapsing MS (RMS).. eighty active RMS were prospectively enrolled, randomized (1:1) to either the IFN-curcumin or the IFN-placebo group and followed up longitudinally with clinical and MRI assessments for 24 months. Primary endpoint was the efficacy of curcumin versus placebo as add-on therapy on new/enlarging T2 lesions in RMS subjects under treatment with subcutaneous IFN β-1a 44 mcg TIW. Efficacy on clinical parameters (relapses and disability progression), other MRI parameters of inflammation (T1 Gd-enhancing lesions, combined unique active-CUA lesions) and neurodegeneration (T1-hypointense lesions, grey matter loss and white matter microstructural damage) as well as safety and tolerability of curcumin were explored as secondary endpoints.. ten subjects dropped out from the study by month 12 (6 in the IFN-curcumin group and 4 in the IFN-placebo group), and 27 by month 24 (11 in the IFN-curcumin group and 16 in the IFN-placebo group). Although no between-group difference was present in terms of proportion of subjects free from new/enlarging T2 lesions, a lower proportion of patients with CUA lesions was noted at month 12 in the IFN-curcumin group in comparison with the IFN-placebo group (7.5% vs 17.5%, χ² test p= 0.0167). This result was not confirmed at month 24. The statistical analysis failed to reveal any difference between the two treatment groups - IFN-curcumin and IFN-placebo - in terms of relapses, disability progression, other MRI metrics of inflammation and MRI changes suggestive of ongoing neurodegeneration. No difference in the rate and nature of adverse events was observed between the two treatment groups.. Although the study drop-out rate was too high to allow definite conclusions, our findings suggest that curcumin might add to IFN β-1a efficacy on radiological signs of inflammation in MS, while it did not seem to exert any neuroprotective effect as assessed by clinical and MRI parameters.

Curcumin's spice-infused therapeutic promise: disease severity alleviation in a mouse model of multiple sclerosis via modulation of immune responses.
Multiple sclerosis (MS) is an autoimmune central nervous system (CNS) disorder indicated by demyelination, chronic inflammation, and neuronal destruction. Regional demyelination, inflammation responses, scar development, and various axonal damage are pathological characteristics of MS. Curcumin is a hydrophobic polyphenol extracted from the rhizome of the turmeric plant. In addition to anti-inflammatory effects, beneficial therapeutic effects such as antioxidant, anti-cancer and nerve protection have also been seen from this compound. The purpose of the current investigation was to provide light on the potential benefits of Curcumin in treating experimental autoimmune encephalomyelitis (EAE), the animal model of MS.. in Female C57BL/6 mice were used to induce EAE through myelin oligodendroglial glycoprotein (MOG). Curcumin doses of 100 and 200 mg/kg were administered orally in the treatment groups starting on the first day of EAE induction. Brains and splenocytes were extracted from euthanized animals on day 25 following EAE induction. Demyelination and leukocyte infiltration, proliferation, cytokine, and gene expression profiles were assessed. Our findings demonstrate that both low and high doses of Curcumin decreased the progression of EAE. Histological analyses revealed low infiltration of leukocytes into the CNS. Curcumin therapy enhanced Th2 and Treg cell secretion of IL-4, IL-10, and TGF-β although considerably decreasing IFN-γ and TNF-α. Curcumin-induced Th2 and Treg cell cytokine production and transcription factor gene expression (IL-13, GATA3, STAT6 and IL-35, CTLA4, Foxp3) and anti-inflammatory cytokines (IL-27, IL-33).. Overall, these findings provide additional evidence that Curcumin can slow disease development and alleviate symptoms in EAE through stimulating Treg and Th2 cell polarization. They support Curcumin's potential therapeutic role in MS.

Curcumin regulates anti-inflammatory responses by AXL/JAK2/STAT3 signaling pathway in experimental autoimmune encephalomyelitis.
Microglia-mediated neuroinflammation plays an important role in multiple sclerosis (MS). This study explored whether curcumin has a protective effect on experimental autoimmune encephalomyelitis (EAE), and the specific mechanism was investigated. We found that curcumin attenuates the severity of EAE mice. It inhibits the activation of microglia in the spinal cord of EAE mice and LPS-stimulated BV-2 cells. The findings clarify that curcumin may inhibit the inflammatory response mediated by microglia by inactivating the AXL/JAK2/STAT3 signaling pathway, which laid a theoretical foundation for the clinical management of MS.

Dual Mechanism of Action of Curcumin in Experimental Models of Multiple Sclerosis.
Multiple sclerosis (MS) is characterized by a combination of inflammatory and demyelination processes in the spinal cord and brain. Conventional drugs generally target the autoimmune response, without any curative effect. For that reason, there is a great interest in identifying novel agents with anti-inflammatory and myelinating effects, to counter the inflammation and cell death distinctive of the disease.. An in vitro assay showed that curcumin (Cur) at 10 µM enhanced the proliferation of C8-D1A cells and modulated the production of Th1/Th2/Th17 cytokines in the cells stimulated by LPS. Furthermore, two in vivo pathophysiological experimental models were used to assess the effect of curcumin (100 mg/kg). The cuprizone model mimics the de/re-myelination aspect in MS, and the experimental autoimmune encephalomyelitis model (EAE) reflects immune-mediated events. We found that Cur alleviated the neurological symptomatology in EAE and modulated the expression of lymphocytes CD3 and CD4 in the spinal cord. Interestingly, Cur restored motor and behavioral deficiencies, as well as myelination, in demyelinated mice, as indicated by the higher index of luxol fast blue (LFB) and the myelin basic protein (MBP) intensity in the corpus callosum.. Curcumin is a potential therapeutic agent that can diminish the MS neuroimmune imbalance and demyelination through its anti-inflammatory and antioxidant effects.

THE ROLE OF DIET IN MULTIPLE SCLEROSIS.
Multiple sclerosis (MS) is a disease of the central nervous system (CNS), characterized by chronic inflammation associated with autoimmune damage to myelin and axons leading to neurodegeneration. Although the etiology is not fully understood, some factors that increase the risk of disease have been identified. One of the key elements of multidisciplinary approach to the management of MS is a properly balanced diet, e.g. Swank diet. Its main assumption is to reduce the supply of animal fats in favor of fats of plant origin, which contain polyunsaturated fatty acids omega-3. One of the factors influencing the course of the disease is vitamin D deficiency. In 80-90% it is synthesized by exposure to the sun, while the other 10-20% may be supplied with ingested food. Although elevated plasma homocysteine levels have been demonstrated in MS patients, there is no need to modify the supply of B vitamins. Further studies are necessary to show the correlation between the supply of B vitamins and the course of the disease. Due to the antioxidant effect, it is recommended to include products that are sources of vitamin A, E and C, glutathione, coenzyme Q10. It is also beneficial to include compounds from the polyphenol group: quercetin, resveratrol and curcumin. Through proper nutrition model it is also possible to reduce side effects of applied medications, such as constipation, what improves patients' quality of life. Diet therapy is a key element supporting pharmacotherapy in patients with multiple sclerosis.

Curcumin β-D-Glucuronide Modulates an Autoimmune Model of Multiple Sclerosis with Altered Gut Microbiota in the Ileum and Feces.
We developed a prodrug type of curcumin, curcumin monoglucuronide (CMG), whose intravenous/intraperitoneal injection achieves a high serum concentration of free-form curcumin. Although curcumin has been reported to alter the gut microbiota and immune responses, it is unclear whether the altered microbiota could be associated with inflammation in immune-mediated diseases, such as multiple sclerosis (MS). We aimed to determine whether CMG administration could affect the gut microbiota at three anatomical sites (feces, ileal contents, and the ileal mucosa), leading to suppression of inflammation in the central nervous system (CNS) in an autoimmune model for MS, experimental autoimmune encephalomyelitis (EAE). We injected EAE mice with CMG, harvested the brains and spinal cords for histological analyses, and conducted microbiome analyses using 16S rRNA sequencing. CMG administration modulated EAE clinically and histologically, and altered overall microbiota compositions in feces and ileal contents, but not the ileal mucosa. Principal component analysis (PCA) of the microbiome showed that principal component (PC) 1 values in ileal contents, but not in feces, correlated with the clinical and histological EAE scores. On the other hand, when we analyzed the individual bacteria of the microbiota, the EAE scores correlated with significant increases in the relative abundance of two bacterial species at each anatomical site: Topics: Animals; Curcumin; Feces; Gastrointestinal Microbiome; Glucuronides; Ileum; Mice; Mice, Inbred C57BL; Multiple Sclerosis; Neuroinflammatory Diseases; RNA, Ribosomal, 16S | 2021 |
Targeted immunomodulation of inflammatory monocytes across the blood-brain barrier by curcumin-loaded nanoparticles delays the progression of experimental autoimmune encephalomyelitis.
It is difficult to carry out early diagnosis and treatment of Multiple sclerosis (MS) because of the complex pathogenesis elicited by diversified autoantigens. Monocytes play important roles in the process of MS, especially as most of the amplified inflammatory monocytes cross the BBB to promote neuron injury and recruit more immune cells to infiltrate the central nervous system (CNS). Here, we propose monocytes as an effective immunotherapy target for MS. We used High-density lipoprotein-mimicking peptide-phospholipid scaffold (HPPS) as a carrier to improve the bioavailability of curcumin. Curcumin-loaded HPPS (Cur-HPPS) were taken up specifically and efficiently by monocytes through the scavenger receptor class B type I (SR-B1) receptor. This delivery hindered inflammatory monocytes across the BBB in EAE mice, inhibited the proliferation of microglia, and restricted the infiltration of other effector immune cells, resulting in the reduction of EAE morbidity from 100% to 30%. It attributed to the immunomodulatory effect of Cur-HPPS on inflammatory monocytes, which inhibited NF-κB activation and downregulated the expression of adhesion-and migration-related molecules. Meanwhile, infiltrated monocytes in the CNS of EAE mice characterize early inflammation. Therefore, targeted modulation of monocytes with HPPS carrying therapeutic and/or imaging agents offers a novel strategy for MS diagnosis and treatment.

Nanocurcumin is a potential novel therapy for multiple sclerosis by influencing inflammatory mediators.
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS). Inflammation has ever been thought as disadvantageous in the pathophysiology of MS. Nanocurcumin has been used as an anti-inflammatory compound. The aim of this study was to identify effects of nanocurcumin on inflammatory mediators in patients with relapsing-remitting multiple sclerosis (RRMS).. Fifty MS patients were randomly divided into two groups. The test group received nanocurcumin capsule daily for 6 months. Simultaneously, the control group received placebo. Real-Time PCR was employed to detect the probable changes in gene expression levels of miRNAs, and miRNA-dependent targets, and also transcription factors and pro-inflammatory cytokines in blood samples. ELISA was used to determine the alterations in these cytokines secretion levels. We have also examined EDSS score in MS patients in two groups.. According to the results, a significant decrease in mRNA expression levels of miR-145 (p<0.0001), miR-132 (p=0.004), miR-16 (p=0.0034), STAT1 (p=0.0002), NF-κB (p<0.0001), AP-1 (p=0.0007), IL-1β (p=0.0017), IL-6 (p=0.017), IFN-γ (p<0.0001), CCL2 (p=0.0067), CCL5 (p=0.0034), TNF-α (p<0.0001) and also significant increase in expression levels of miRNAs targets; Sox2 (p=0.0001), sirtuin-1(p=0.0007), Foxp3 (p=0.0082), PDCD1 (p=0.003) was evident in nanocurcumin treated group compared with before treatment. The secretion levels of IFN-γ (p=0.0025), CCL2 (p=0.0029), and CCL5 (p=0.0003) were reduced dramatically in test group compared with placebo group.. In conclusion, nanocurcumin may be more effective on the inflammatory features of MS. According to present results, nanocurcumin may inhibit neuroinflammation in MS patients.

Study of curcumin immunomodulatory effects on reactive astrocyte cell function.
Multiple sclerosis (MS) is considered an inflammatory and neurodegenerative disease of the central nervous system (CNS) which most often presents as relapsing-remitting episodes. Recent evidence suggests that activated astrocytes play a dual functional role in CNS inflammatory disorders such as MS. In this study, we tried to induce anti-inflammatory functions of astrocytes by curcumin. The effects of curcumin were examined on human a astrocyte cell line (U373-MG) induced by lipopolysaccharide (LPS) in vitro. Matrix metalloproteinase (MMP)-9 activity was assessed by gelatin zymography. Cytokine levels were evaluated by quantitative ELISA method and mRNA expression was measured by real-time PCR. We found that curcumin decreased the release of IL-6 and reduced MMP-9 enzyme activity. It down-regulated MCP-1 mRNA expression too. However, curcumin did not have significant effects on the expression of neurotrophin (NT)-3 and insulin-like growth factor (IGF)-1 mRNAs. Results suggest that curcumin might beneficially affect astrocyte population in CNS neuroinflammatory environment lean to anti-inflammatory response and help to components in respects of CNS repair. Our findings offer curcumin as a new therapeutic agent with the potential of regulating astrocyte-mediated inflammatory diseases in the CNS.

Curcumin serves as a human kv1.3 blocker to inhibit effector memory T lymphocyte activities.
Curcumin, the principal active component of turmeric, has long been used to treat various diseases in India and China. Recent studies show that curcumin can serve as a therapeutic agent for autoimmune diseases via a variety of mechanisms. Effector memory T cells (T(EM), CCR7⁻ CD45RO⁺ T lymphocyte) have been demonstrated to play a crucial role in the pathogenesis of T cell-mediated autoimmune diseases, such as multiple sclerosis (MS) or rheumatoid arthritis (RA). Kv1.3 channels are predominantly expressed in T(EM) cells and control T(EM) activities. In the present study, we examined the effect of curcumin on human Kv1.3 (hKv1.3) channels stably expressed in HEK-293 cells and its ability to inhibit proliferation and cytokine secretion of T(EM) cells isolated from patients with MS or RA. Curcumin exhibited a direct blockage of hKv1.3 channels in a time-dependent and concentration-dependent manner. Moreover, the activation curve was shifted to a more positive potential, which was consistent with an open-channel blockade. Paralleling hKv1.3 inhibition, curcumin significantly inhibited proliferation and interferon-γ secretion of T(EM) cells. Our findings demonstrate that curcumin is able to inhibit proliferation and proinflammatory cytokine secretion of T(EM) cells probably through inhibition of hKv1.3 channels, which contributes to the potency of curcumin for the treatment of autoimmune diseases. This is probably one of pharmacological mechanisms of curcumin used to treat autoimmune diseases.

Amelioration of experimental autoimmune encephalomyelitis by curcumin treatment through inhibition of IL-17 production.
Experimental autoimmune encephalomylitis (EAE), an animal mode of multiple sclerosis (MS), was previously considered that be mediated by Th1 cells. However, a number of recent studies provided strong evidence that T helper cells that produce IL-17 play a dominant role in the pathogenesis of EAE. Curcumin (1,7-Bis 94-hydroxy-3-methoxyphenyl)-1,6 heptadiene-3, 5-di-one) is a naturally occurring polyphenolic phytochemical isolated from the rhizome of the medicinal plant Curcuma longa. It has been strongly implicated as an anti-inflammatory agent, but the precise mechanisms of its action are largely unknown. In the present study, we have investigated the efficacy and mechanism of curcumin against EAE. The treatment of Lewis rats with curcumin significantly reduced the clinical severity of EAE, and had a dramatic reduction in the number of inflammatory cells infiltration in the spinal cord. The proliferation of the MBP-reaction lymphocyte also was reduced in a curcumin dose-dependent manner. Furthermore, the mRNA expression of the cytokine profiles was assessed by quantitative reverse-transcription polymerase chain reaction (qRT-PCR), revealing the dramatic decrease of IL-17, TGF-beta, IL-6, IL-21, STAT3, and RORgammat expression in curcumin-treated groups and STAT3-phosphorylation also was inhibited. These findings indicated that curcumin amelioration EAE was, to a large extent, due to inhibit differentiation and development of Th17 cells depends on down-regulating expression of IL-6, IL-21, RORgammat signaling and inhibition STAT3-phosphorylation, suggests it is useful in the treatment of MS and other Th17 cell-mediated inflammatory diseases.

15-deoxy-Delta(12,14)-prostaglandin J(2) and curcumin modulate the expression of toll-like receptors 4 and 9 in autoimmune T lymphocyte.
Experimental allergic encephalomyelitis (EAE) is a T cell-mediated autoimmune disease model for multiple sclerosis (MS). We have shown earlier that 15-deoxy-Delta(12,14)-prostaglandin J(2) (15d-PGJ(2)) and curcumin ameliorate EAE by modulating inflammatory signaling pathways in T lymphocytes. Toll-like receptors (TLRs), expressed primarily in innate immune cells, play critical roles in the pathogenesis of EAE. T lymphocytes also express TLRs and function as costimulatory receptors to upregulate proliferation and cytokine production in response to specific agonists.. In this study, we show that naïve CD4(+) and CD8(+) T cells express detectable levels of TLR4 and TLR9 and that increase after the induction of EAE in SJL/J and C57BL/6 mice by immunization with PLPp139-151 and MOGp35-55 antigen, respectively. It is interesting to note that in vivo treatment with 15d-PGJ2 or curcumin results in a significant decrease in TLR4 and TLR9 expression in CD4(+) and CD8(+) T cells in association with the amelioration of EAE.. Although the exact mechanisms are not known, the modulation of TLR expression in T lymphocytes by 15d-PGJ(2) and curcumin suggests new therapeutic targets in the treatment of T cell-mediated autoimmune diseases.

Curcumin: getting back to the roots.
The use of turmeric, derived from the root of the plant Curcuma longa, for treatment of different inflammatory diseases has been described in Ayurveda and in traditional Chinese medicine for thousands of years. The active component of turmeric responsible for this activity, curcumin, was identified almost two centuries ago. Modern science has revealed that curcumin mediates its effects by modulation of several important molecular targets, including transcription factors (e.g., NF-kappaB, AP-1, Egr-1, beta-catenin, and PPAR-gamma), enzymes (e.g., COX2, 5-LOX, iNOS, and hemeoxygenase-1), cell cycle proteins (e.g., cyclin D1 and p21), cytokines (e.g., TNF, IL-1, IL-6, and chemokines), receptors (e.g., EGFR and HER2), and cell surface adhesion molecules. Because it can modulate the expression of these targets, curcumin is now being used to treat cancer, arthritis, diabetes, Crohn's disease, cardiovascular diseases, osteoporosis, Alzheimer's disease, psoriasis, and other pathologies. Interestingly, 6-gingerol, a natural analog of curcumin derived from the root of ginger (Zingiber officinalis), exhibits a biologic activity profile similar to that of curcumin. The efficacy, pharmacologic safety, and cost effectiveness of curcuminoids prompt us to "get back to our roots."
