The NLRP3 inflammasome is an intracellular sensor that detects damage-associated molecular patterns (DAMPs) and pathogen-associated molecular patterns (PAMPs) and represents a crucial component of innate immune responses in the airways [7, 8]. It was found that caspase-1 and ASC knockout mice had less recruitment of microglia and. Pyroptosis is a proinflammatory programmed cell de. The most important player in IP activation is the NLRP3 (NOD [Nuclear oligomerization domain]-, LRR [Leucine rich repeat]- and pyrin domain-containing protein 3) which functions as an intracellular sensor of D/M/L-AMPs resulting in activation of caspase-1, promotion of apoptosis, pyroptosis and generation of inflammatory cytokines. The inflammasome activation is linked with stress, infection, and/or other immunological signals involved in inflammation. The NLRP3 inflammasome appears to be activated by changes in intracellular potassium caused by potassium efflux from mechanosensitive ion channels located in the cell membrane. | Find, read and cite all the research you need . Danger signals are a hallmark of various inflammatory diseases, where these signals activate NLRP3. Dysregulated Inflammasome Activation and Its Regulation. The NLRP3 inflammasome has been recognised as a key component of the innate immune response In AD. NLRP3 broadly senses infectious patterns and sterile danger signals, resulting in the tightly coordinated and regulated assembly of the NLRP3 inflammasome, but the precise mechanisms are. In contrast to the anticipated minimal, or perhaps absent, role of Nlrp3 in the pathogenesis of pulmonary tularemia, we find that Nlrp3 is a host susceptibility factor.
