Linkage between coenzyme a metabolism and inflammation: roles of pantetheinase.
    Journal of pharmacological sciences, 2013, Sep-20, Volume: 123, Issue:1

    Pantetheinase is an enzyme hydrolyzing pantetheine, an intermediate of the coenzyme A degradation pathway. Pantetheinase has long been considered as the enzyme that recycles pantothenic acid (vitamin B5) generated during coenzyme A breakdown. Genetic analyses showed that mammals have multiple genes known as vanin family genes. Recent studies using mice lacking the vanin-1 gene (pantetheinase gene) suggest that pantetheinase is actively involved in the progression of inflammatory reactions by generating cysteamine. Additional studies using human leukocytes demonstrate that human neutrophils have abundant pantetheinase proteins on the surface and inside the cells. The second pantetheinase protein, GPI-80/VNN2, is suggested to work as a modulator of the function of Mac-1 (CD11b/CD18), an adhesion molecule important to neutrophil functions. This review delineates the characteristics of the pantetheinase/vanin gene family and how they affect inflammation.

Diverse biological activities of the vascular non-inflammatory molecules - the Vanin pantetheinases.
    Biochemical and biophysical research communications, 2012, Jan-13, Volume: 417, Issue:2

    The Vanin genes are a family that encode pantetheinases involved in recycling Coenzyme A, catalysing the breakdown of intermediate pantetheine to vitamin B5 for reuse in CoA biosynthesis. The role of pantetheinase in this most fundamental of cellular processes, was substantially characterised by the 1970s. The next 20 years saw little further interest in pantetheinase until various genetic studies implicated the Vanin locus in a range of normal and disease phenotypes, and a consequent interest in the other product of pantetheinase activity, cysteamine. This report seeks to bring together the early biochemical studies with recent biological data implicating cysteamine as a regulator of the oxidative state of a cell. Numerous studies now report a role for Vanin in inflammation, oxidative stress, cell migration and numerous diseases including cardiovascular disease.

Metabolic changes and inflammation in cultured astrocytes from the 5xFAD mouse model of Alzheimer's disease: Alleviation by pantethine.
    PloS one, 2017, Volume: 12, Issue:4

    Astrocytes play critical roles in central nervous system homeostasis and support of neuronal function. A better knowledge of their response may both help understand the pathophysiology of Alzheimer's disease (AD) and implement new therapeutic strategies. We used the 5xFAD transgenic mouse model of AD (Tg thereafter) to generate astrocyte cultures and investigate the impact of the genotype on metabolic changes and astrocytes activation. Metabolomic analysis showed that Tg astrocytes exhibited changes in the glycolytic pathway and tricarboxylic acid (TCA) cycle, compared to wild type (WT) cells. Tg astrocytes displayed also a prominent basal inflammatory status, with accentuated reactivity and increased expression of the inflammatory cytokine interleukin-1 beta (IL-1β). Compensatory mechanisms were activated in Tg astrocytes, including: i) the hexose monophosphate shunt with the consequent production of reducing species; ii) the induction of hypoxia inducible factor-1 alpha (HIF-1α), known to protect against amyloid-β (Aβ) toxicity. Such events were associated with the expression by Tg astrocytes of human isoforms of both amyloid precursor protein (APP) and presenilin-1 (PS1). Similar metabolic and inflammatory changes were induced in WT astrocytes by exogenous Aβ peptide. Pantethine, the vitamin B5 precursor, known to be neuroprotective and anti-inflammatory, alleviated the pathological pattern in Tg astrocytes as well as WT astrocytes treated with Aß. In conclusion, our data enlighten the dual pathogenic/protective role of astrocytes in AD pathology and the potential protective role of pantethine.

Pantethine Down-Regulates Leukocyte Recruitment and Inflammatory Parameters in a Mouse Model of Allergic Airway Inflammation.
    Medical science monitor basic research, 2017, Nov-27, Volume: 23

    BACKGROUND Migration of leukocytes into airways is the hallmark of allergic asthma. The aim of this study was to target the pathological process using pantethine, a pleiotropic natural compound which has been recently shown to down-regulate chemokine-driven T cell migration. MATERIAL AND METHODS Mice were sensitized to the Leishmania LACK antigen, then treated or not treated with pantethine and exposed to LACK or saline aerosol. After sacrifice of the animals, cells in the bronchoalveolar lavage were analyzed and inflammatory parameters were determined to evaluate inflammation seriousness. RESULTS As compared to untreated animals, pantethine-treated animals displayed a moderated response to the allergen, as documented by decreased infiltration of inflammatory cells (all types), in addition to reduced levels of lung Th2 cytokines and circulating LACK-specific IgE. CONCLUSIONS These data reveal the potential therapeutic importance of pantethine to moderate allergic asthma pathology. The compound has been previously shown to exert a broad range of protective activity in animals and in humans, with few or no adverse effects.
