Abstract
ObjectivesTo observe the intervention influence and effect of simvastatin on the expression of interleukin 17 (LI17), high mobility group protein 1 (HMGB1) and TLR4 path in Lupus nephritis (LN) rats. MethodsA total of 28 BSXSB male mice with LN (16 weeks) were randomly divided into observation group and the comparison group, observation group was given 6 mg•kg−1•d−1 simvastatin in 0.1% PBS lavage for 4 weeks, the comparison group was not given any treatment. Blood urea nitrogen (BUN) level and urine trace albumin (Scr) level of two groups were determined. The expression of IL17, HMGB1 and TLR4 protein was detected using immune histochemical method, and the kidney histological damage was observed. ResultsBNU, LI17, HMGB1, TLR4 protein and HMGB1 mRNA in observation group was significantly lower than that in control group (P<0.05); There was no statistical difference of Scr level between two groups (P>0.05). Histological observation showed glomerular lesions integral of observation group was obviously lower than that of control group. ConclusionsSimvastatin can reduce the expression of IL17, HMGB1 and TLR4 protein in LN mice, thereby can inhibit the autoimmune response as a potential treatment function of LN.
