Pyroptosis plays an important role in hemorrhagic stroke.Excessive endoplasmic reticulum stress can cause endoplasmic reticulum dysfunction and cellular pyroptosis by regulating the nucleotide-binding oligomerization ...Pyroptosis plays an important role in hemorrhagic stroke.Excessive endoplasmic reticulum stress can cause endoplasmic reticulum dysfunction and cellular pyroptosis by regulating the nucleotide-binding oligomerization domain and leucine-rich repeat pyrin domain-containing protein 3(NLRP3)pathway.However,the relationship between pyroptosis and endoplasmic reticulum stress after intraventricular hemorrhage is unclear.In this study,we established a mouse model of intraventricular hemorrhage and found pyroptosis and endoplasmic reticulum stress in brain tissue.Intraperitoneal injection of the selective GPR120 agonist TUG-891 inhibited endoplasmic reticulum stress,pyroptosis,and inflammation and protected neurons.The neuroprotective effect of TUG-891 appears related to inhibition of endoplasmic reticulum stress and pyroptosis activation.展开更多
