Abstract

Multiple sclerosis (MS) is the most abundant central nervous system (CNS) inflammatory disease, which is due to the reaction of auto reactive T cells with own myelin proteins, leading to physical disorder and paralysis among people suffering the disease. Hesperidin, a flavanone glycoside found abundantly in citrus fruits possesses a wide range of pharmacological properties including potential anti-inflammatory and anti-cancer effects. This study was designed to reveal the molecular and cellular mechanisms underlying the effect of hesperidin on MS alleviation. Female C57BL/6 mice were immunized with MOG35-55. Clinical scores and other parameters were monitored daily for the 21days. At the end of the period, brain/spinal cord histology was performed to measure lymphocyte infiltration; T-cell profiles were determined through ELISA, flow cytometry, and real-time PCR. Transcription factor expression levels in the CNS were assessed using real-time PCR; T cell differentiation was evaluated via flow cytometry. The results demonstrated that hesperidin inhibited development of EAE. Histological studies revealed limited leukocyte infiltration into the CNS. Hesperidin increased Treg cells production of interleukin IL-10 and transforming growth factor (TGF)-β, but concurrently resulted in a significant reduction in production of IL-17 and IL-6. Flow cytometry revealed there were also significant decreases in the percentages of Th17 cells, as well as significant increase in percentages of Treg cells in the spleen and lymph nodes. Real-time PCR results indicated hesperidin treatment reduced ROR-γt factor expression, but enhanced Foxp3 expression. Collectively, these results demonstrated that hesperidin could reduce the incidence and severity of disease.
