General Information

General Information Comment Organism
physiological function lysosome exocytosis is a conserved caspase-1-dependent feature of pyroptosis. Caspase-1 activation leads to increased membrane permeability and an influx of calcium, which results in fusion of lysosomes with the cell surface and release of lysosomal contents. Secretion of processed IL-1beta and IL-18 in macrophages undergoing pyroptosis occurs independently of lysosome exocytosis. Multiple stimuli, acting through a diverse set of NLR proteins, lead to two conserved caspase-1-dependent secretion events: the release of processed inflammatory cytokines and lysosome-mediated release of antimicrobial host factors and degraded microbial products Mus musculus
