“…91 Additionally, the anthracycline doxorubicin induces systemic inflammation associated with IL-1b release, mediated by NLRP3 inflammasome activation, which is controlled by co-treatment with ROS inhibitors or by cultivation of cells with high levels of extracellular K 1 . 92 Lysosomal destabilization and activation of the NLRP3 inflammasome In addition to ROS and K 1 efflux, disruption of the lysosomal membrane, caused by phagocytosis of particulate matter or live pathogens or by sterile lysosomal damage (without crystals), results in NLRP3 activation. 55,57 In agreement with this, proton pump inhibitors (used for neutralization of lysosomal pH) or blockade of cathepsin(s) significantly inhibits NLRP3 inflammasome activation.…”
