Abstract:
Objective To investigate the effects of atorvastatin on the experimental autoimmune encephalomyelitis(EAE)and the underlying mechanism of immunoregulation.Method The Wistar rats were used to establish EAE model.After oral administration of 2, 8 mg? kg~(1)?d~(1)of atorvastatin, the rats were examined for the development of neurological signs, changes of histopathology and the expression of IL-4 and MMP-9.Result Though high dose treatment with atorvastatin, the frequency of EAE attacks degreased from 76.67% to 33.33%(P=0.008);the extent of inflammation degreased from 3.2?1.1 to 1.3?0.4(P=0.01);and the number of MMP-9 positive cells degreased from 37?7 to 26?5(P= 0.001), the expression of IL-4 could be increased from(0.35?0.12)ng/ml to(0.68?0.23)ng/ml (P=0.05).Conclusion Atorvastatin can reduce the inflammation and produce the recover of the neurological harm because of the changes of MMP-9 and IL-4.
