RESUMEN

Aim To explore the protective effects of ganoderma lucidum polysaccharides (GLPS) on experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS) and the underlying mechanism.

RESUMEN

Objective:To explore the neuroprotective effect and mechanism of Buyang Huanwu Tang (BYHWT) on experimental autoimmune encephalomyelitis (EAE) at different stages. Method:The 36 female C57BL/6 mice were immunized subcutaneously with myelin oligodendrocyte glycoprotein peptides (MOG35-55),then randomly divided into 9, 17, 28 d EAE control group. Each BYHWT group was orally given drugs on the 3rd day after immunization (50 g·kg-1·d-1), and EAE control group was given the same volume of normal saline in the same way once a day for 9, 17 and 28 d after immunization. The effect of BYHWT on EAE mice was observed with internationally accepted clinical score. Brain and spinal cord specimens were collected at 9, 17 and 28 d after immunization. The neuroprotective effect of BYHWT was observed by hematoxylin-eosin(HE)staining and solid blue staining (LFB). The expressions of BDNF and GAP-43 in spinal cord and brain were detected by Western blot. Result:After treatment, BYHWT can significantly inhibit myelitis cell infiltration and alleviate myelin loss. Compared with EAE group, the expression of Nogo-A in the spinal cord of each BYHWT group was significantly down-regulated (PPPPConclusion:BYHWT can improve the local nerve growth microenvironment and promote the expression of NTFs, reduce the expressions of neuroinhibitory factors, and play a role in neuroprotection.
