Inflammasome is composed of apoptosis-associated speckle-like protein(ASC),caspase-1 and pattern recognition receptors(PRR).Inflammasome plays an important role in the process of tumorigenesis,including the regulation of tumor biological behavior,pyroptosis and immunity.Targeting inflammasome may provide new ideas for tumor treatment and prognosis improvement.Gliomas are highly malignant brain tumors with poor prognosis in the central nervous system.This article reviews the composition,activation mechanism and the role of inflammasome in gliomas.
