Abstract： The mechanism of ischemic stroke development has not been fully elucidated, but inflammatory damage has been recognized to play an important role. Activation of Toll-like receptor 4 (TLR4)-related signaling pathways can promote the expressions of pro-inflammatory cytokines and anti-inflammatory cytokines associated with ischemic stroke, thereby affecting the progression and prognosis of ischemic stroke. The author reviews the research progress of TLR4-related signaling pathways in inflammatory injury of ischemic stroke, in order to provide some ideas and references for the discovery of targeted TLR4 anti-inflammatory drugs that can be used for ischemic stroke treatment.
