CPD-4645 rescued neuronal cell loss and cognitive deficit and reduced interleukin (IL)-1β and cyclooxygenase 2 (COX-2) brain expression resulting from SE.
FTY720 alleviated the overexpression of hippocampal P-gp in SE rats and reduced NF-κB activity and TNF-α and COX-2 expression, and W146 blocked the effects of FTY720.
Our qRT-PCR exerted that there was a continuous elevation of iNOS and COX-2 genes expression over 6 and 24h after pilocarpine administration in SE and L-arginine+Zolpidem groups while in AG/L-NAME+Zolpidem and zolpidem groups this upregulation was prevented.
Rifampicin pretreatment attenuated SE-induced neuroinflammation and decreased the hippocampal expression of interleukin-1β, tumor necrosis factor-α, nuclear factor kappa-B, and cyclooxygenase-2.
Triple immunohistochemistry demonstrated no overlap of COX2 labeling with Ox42, in addition to a decrease in COX2/GFAP-co-immunoreactivity in the group treated with 60 mg/kg HE, suggesting that the reduction of COX2 by HE promotes neuroprotection after SE.
