Dear Editor,A rapid immune response to signals released from pathogens and injuries is critical for maintaining tissue integrity and restoring *** response is largely mediated by the concerted action of pattern recognition receptors(PRRs).Such cooperativity has been described for Toll-like receptors(TLRs)and NACHT,LRR,and pyrin domain-containing protein 3(NLRP3),but the underlying molecular mechanisms remain incompletely *** are multi-protein complexes defined by a cytosolic innate immune sensor,usually a PRR,which recruits the adaptor molecule apoptosis-associated speck-like protein containing a caspase-recruitment domain(ASC)to activate the effector caspase-1 leading to the release of matured IL-1βand *** caspase-1 further cleaves gasdermin D(GSDMD)allowing the N-terminal domain of GSDMD(GSDMD-N)to form pores in the plasma membrane,thus facilitating the release of matured IL-1βand ***-forming GSDMD-N further induces pyroptosis,an inflammatory form of cell death.
