Abstract
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.
