RESUMO
Neuropsychiatric and neurological disorders pose a significant global health burden, highlighting the need for innovative therapeutic approaches. Fingolimod (FTY720), a common drug to treat multiple sclerosis, has shown promising efficacy against various neuropsychiatric and neurological disorders. Fingolimod exerts its neuroprotective effects by targeting multiple cellular and molecular processes, such as apoptosis, oxidative stress, neuroinflammation, and autophagy. By modulating Sphingosine-1-Phosphate Receptor activity, a key regulator of immune cell trafficking and neuronal function, it also affects synaptic activity and strengthens memory formation. In the hippocampus, fingolimod decreases glutamate levels and increases GABA levels, suggesting a potential role in modulating synaptic transmission and neuronal excitability. Taken together, fingolimod has emerged as a promising neuroprotective agent for neuropsychiatric and neurological disorders. Its broad spectrum of cellular and molecular effects, including the modulation of apoptosis, oxidative stress, neuroinflammation, autophagy, and synaptic plasticity, provides a comprehensive therapeutic approach for these debilitating conditions. Further research is warranted to fully elucidate the mechanisms of action of fingolimod and optimize its use in the treatment of neuropsychiatric and neurological disorders.
RESUMO
BACKGROUND: Oxidative stress is strongly associated with development of diabetes mellitus. F. vulgaris, contains antioxidant ingredients. This study was designed in order to evaluate the effect of F. vulgaris on the damaged liver in diabetic rats. METHODS: In this study, hydroalcoholic extract of F. vulgaris was prepared. Sixty four male rats were divided into 8 groups (n = 8), including saline (normal control), streptozotocin (STZ) (diabetic control) (60 mg/kg), F. vulgaris (50, 100, 150 mg/kg), and STZ plus F. vulgaris (50, 100, 150 mg/kg) were administered through oral gavage on treated group once a day for 28 consecutive days. Serum nitrite oxide (NO) level, Ferric reducing/antioxidant power (FRAP), Malondialdehyde (MDA), liver weight, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), diameter of hepatocytes and central hepatic vein have been examined. Statistical analysis was performed using one-way analysis of variance and the post hoc test. RESULT: The outcomes showed that administrating streptozotocin enhanced liver MDA, nitrite oxide, the mean diameter of central hepatic vein and hepatocyte, liver enzymes significantly and reduced liver weight compared to saline group (P < 0.05). Though, administrating F. vulgaris and F. vulgaris plus STZ enhanced liver weight and tissue FRAP level significantly and reduced liver enzymes, NO levels, liver MDA, the mean diameter of hepatocyte and central hepatic vein in entire doses were equal to STZ group (P < 0.05). CONCLUSION: It seems that, were equal F. vulgaris might recover liver injuries in diabetic rats.
