lysosomeMembrane-enclosed structure, or organelle, inside a cell, principally found in animal cells. Lysosomes contain enzymes that can break down proteins and other biological substances.

Hemocytic lysosome response in the snail Helix aspersa after exposure to the fungicide copper oxychloride. The researchers posit that nerve cells hungry for choline compounds raid their own cell membranes for phosphatidylcholine; this leaves holes on the underside of the membrane and possibly exposes portions of APP to marauding lysosomes. Given that during synthesis of the C/Fe particulates, the material is subjected to extreme acidification procedures, the acidification reached in a lysosome would not be sufficient to decompose the particle. |
