Lysosome membrane lipid composition
WebThe lysosome is a membrane-bound vesicle containing hydrolase enzymes that break down old organelles and proteins into small molecules, such as amino acids. Lysosome’s membrane is similar to the cell membrane or endoplasmic reticulum (ER) since lysosomes are budded from the ER-Golgi system. WebIn the past decade, lysosomal membrane permeabilization (LMP) has emerged as a significant component of cell death signaling. The mechanisms by which lysosomal stability is regulated are not yet fully understood, but changes in the lysosomal membrane lipid composition have been suggested to be involved.
