We also detected the expression of interleukin-1 receptor-associated protein kinases-1 (IRAK1) and tumor necrosis factor receptor-associated factor 6 (TRAF6) and nuclear factor-kappaB (NF-κB) p65 using Western blotting and immunohistochemistry, which indicated the expression of IRAK1, TRAF6 and NF-κB p-p65/p65 increased in the brain of SE rats, and overexpression of miR-146a-5p could downregulate the expression of IRAK1, TRAF6, NF-κB p-p65/p65 and P-gp.
