abstract：:Inflammasomes are large multimolecular complexes present in the cytosol of stimulated immune cells; they mediate the activation of caspase-1, leading to cellular pyroptosis. So far, a variety of studies on inflammasomes have emerged, and the best-studied is the NLRP3 inflammasome that is involved in many inflammatory ...
