Astragaloside IV might exert anti-inflammatory effects by inhibiting toll-like receptor 4 (TLR4) signaling pathway and nucleotide binding oligomerization domain-like receptors P3 (NLRP3) inflammasome overactivation in order to prevent transient cerebral ischemia and reperfusion injury [19]. The gene discussed is NLRP3; the disease is transient ischemic attack.
