If damage is limited, cells can repair lysosomes by means of the endosomal sorting complex required for transport (ESCRT) machinery. Presumably, if repair fails, … glitched text fontWebLysosomal membrane permeabilization (LMP) is one mechanism inducing cell death and the most studied form of lysosome-dependent cell death. When LMP occurs, lysosomal contents, including many acid proteases, leak into the cytoplasm, destroying critical proteins and resulting in cell death. We therefore tested whether DSF triggered LMP in GBM cells. glitched terraria seeds
