Web14 hours ago · Lysosomes containing acid hydrolases can degrade macromolecules from autophagic membrane trafficking pathways, which is indispensable for maintenance of autophagy (Luzio et al. 2007). It has been demonstrated that CTSB from lysosomes in necrotic or damaged cells contributes to the activation of the NLRP3 inflammasome … WebMay 1, 2024 · CTSB is a proteolytic enzyme that is primarily localized to the lysosomes [10]. To further examine whether CTSB released from lysosomes is involved in the activation of NLRP3 inflammasomes, we investigated the expression of activated CTSB, NLRP3, ASC, and caspase-1p20 in the control group, AP group, and CTSB inhibitor group.
