Inflammasomes formed by some NLRs activate

Cytosolic NOD-like receptors detect microbial products or danger signals and can assemble multiprotein inflammasomes that activate caspase-1. Caspase-1 processes the pro-inflammatory cytokines IL-1β and IL-18 and also cleaves gasdermin D to induce pyroptosis. Inflammasome activation therefore links intracellular sensing to both cytokine release and inflammatory cell death. Careful

Cathelicidin (LL-37) becomes active after

Antimicrobial peptides such as defensins and cathelicidins are cationic molecules that disrupt microbial membranes by forming pores or micelles. α-Defensins are stored in neutrophil granules and Paneth cells, while β-defensins are produced by epithelial cells. Their broad-spectrum activity constitutes an important chemical barrier of innate immunity at mucosal and epithelial surfaces.
