DPP-4 inhibitors and type 2 diabetes mellitus in Parkinson's disease: a mutual relationship.
    Pharmacological reports : PR, 2023, Volume: 75, Issue:4

    Parkinson's disease (PD) usually occurs due to the degeneration of dopaminergic neurons in the substantia nigra (SN). Management of PD is restricted to symptomatic improvement. Consequently, a novel treatment for managing motor and non-motor symptoms in PD is necessary. Abundant findings support the protection of dipeptidyl peptidase 4 (DPP-4) inhibitors in PD. Consequently, this study aims to reveal the mechanism of DPP-4 inhibitors in managing PD. DPP-4 inhibitors are oral anti-diabetic agents approved for managing type 2 diabetes mellitus (T2DM). T2DM is linked with an increased chance of the occurrence of PD. Extended usage of DPP-4 inhibitors in T2DM patients may attenuate the development of PD by inhibiting inflammatory and apoptotic pathways. Thus, DPP-4 inhibitors like sitagliptin could be a promising treatment against PD neuropathology via anti-inflammatory, antioxidant, and anti-apoptotic impacts. DPP-4 inhibitors, by increasing endogenous GLP-1, can also reduce memory impairment in PD. In conclusion, the direct effects of DPP-4 inhibitors or indirect effects through increasing circulating GLP-1 levels could be an effective therapeutic strategy in treating PD patients through modulation of neuroinflammation, oxidative stress, mitochondrial dysfunction, and neurogenesis.

Sitagliptin and liraglutide reversed nigrostriatal degeneration of rodent brain in rotenone-induced Parkinson's disease.
    Inflammopharmacology, 2017, Volume: 25, Issue:3

    The present study investigated the possible relationship between pro-inflammatory cytokines and programmed nigral neuronal death in rotenone model of Parkinson's disease (PD). Sitagliptin and liraglutide efficacy to inhibit the inflammatory-apoptotic degenerative process were investigated, too. The experimental PD were induced in male albino rats by ten subcutaneously injections of rotenone (3 mg/kg/day, s.c). All treatment drugs were administered for 16 days after induction of Parkinson rat's model. Sitagliptin and liraglutide were administered in three different dose levels (10-20-30 mg/kg, p.o), (25-50-100 μg/kg, s.c), respectively. Cylindrical and catalepsy tests were used to detect the optimum dose response of each drug. Sitagliptin (30 mg/kg/day, p.o) and liraglutide (50 μg/kg, s.c.) showed statistically significant (p ≤ 0.05) effect on behavioral activity. Where both doses improved the motor performance significantly in comparison with other doses in both cylindrical and catalepsy tests. Furthermore, they reversed rotenone-induced nigral neuronal loss, associated with marked decrease of pro-inflammatory cytokines: interleukin (IL)-1β, IL-6, transforming growth factor (TGF)-β1, together with a significant increase of striatal dopamine, nigral glial cell line-derived neurotrophic factor (GDNF), and tyrosine hydroxylase positive (TH+) cells. Moreover, the pro-apoptotic environment in nigrostriatal tissues was abrogated significantly, as the pro-apoptotic protein Bax decreased along with the anti-apoptotic protein Bcl-2 increased. In conclusion, sitagliptin and liraglutide represent a promising strategy to mitigate the progression of PD by their anti-inflammatory, anti-apoptotic neurotrophic and neurogenic mechanistic activities.
