Abstract

Inflammatory microglia and P2X7R are involved in the development of stress-induced depression. Endoplasmic reticulum (ER) stress and mitochondrial damage play an important role in depression and microglial activation. Bullatine A (BLA) has anti-inflammatory and anti-rheumatic effects, and can be used as a P2X7R antagonist. We found that Bullatine A can effectively inhibit the calcium overload of mitochondria and the increase of ER and mitochondrial colocalization caused by eATP (extracellular ATP) in BV2-cells. Bullatine A can also inhibit the activation of PERK-elF-2α unfolded protein response (UPR), lysosome production and the increase of NLRP3 inflammasome protein expression in BV2-cells Both intragastric administration and intra-hippocampal microinjection of Bullatine A can significantly improve the despair behavior but not anhedonia of Chronic chronic social defeat stress (CSDS) mice. Bullatine A may have a beneficial therapeutic effect in treating diseases related to stress stimulation, such as depression.
