Neuroprotective effects of selective estrogen receptor modulators in cerebral ischemia / 国际脑血管病杂志

Selective estrogen receptor modulators tamoxifen,raloxifene,and bazedoxifene reduce neuronal death through the mechanisms of anti-inflammation,antioxidant stress,and inhibition of glutamate excitotoxicity.They play a neuroprotective role in cerebral ischemia and may become a new neuroprotective agent for the treatment of ischemic stroke.

Roles of microglia in cerebral ischemia / 国际脑血管病杂志

Microglia play a crucial role in inflammation after cerebral ischemia.A large number of studies have shown that microglia are highly plastic cells that can assume different phenotypes and functions in response to specific microenvironmental signals.Microglia can be polarized into the classically activated proinflammatory M1 phenotype or the alternatively activated anti-inflammatory M2 phenotype,and play different roles in ischemic injury.Irnhibiting M1 while stimulating M2 may be a new approach for the treatment of ischemic stroke.

Roles of CD200 and CD200R in cerebral ischemia / 国际脑血管病杂志

Inflammation plays an important role in the pathophysiological mechanism of acute ischemic stroke.CD200 expressed in neurons interacts with CD200 receptor (CD200R) on microglia cells.It can inhibit microglia activation and alleviate the inflammation after cerebral ischemic injury.This article reviews the roles of CD200 and CD200R in the activation of microglia after cerebral ischemia.
