WebConcluding remarks and remaining questions. In summary, the NAIP/NLRC4 inflammasome senses bacterial components in the host cell cytosol and induces a cascade of inflammatory events to mediate host defense against bacterial pathogens. Recent studies have revealed species-specific NAIP/NLRC4 inflammasome responses. WebPRRs comprise an array of sensors present in the plasma, plasma membranes, and host cytosol. The existence of multiple PRRs capable of recognizing a single microorganism ensures the induction of immune responses even when a sensor or its signaling pathway is targeted by the pathogen.
