Figure Lengend Snippet: Graphical summary. Extracellular particles containing LAMP3 are released by LAMP3-overexpressing cells and taken up by a neighboring LAMP3-naïve cell. This results in LAMP3 protein transfer to the cytoplasm of the naïve cell. Here, LAMP3 induces lysosomal membrane permeabilization (LMP), leading to apoptotic cell death.
