He observed that the lysosomes described by de Duve contained fragments of the labeled proteins, and concluded that proteins were degraded in the lysosome (Straus 1954).

Those are proteins that break stuff down. Our cells use lysosomes to help destroy germs or recycle old or messed up cell parts. Lysosomes are basically the cell’s trash and recycling centers.

The duplication and division of cells is critical to keeping all multicellular organisms alive. But the opposite process is equally important: cell death. Controlled death of cells, or programmed ...

LSDs are a group of over 50 rare genetic disorders caused by problems in the lysosome's recycling process. Diseases like Gaucher disease, Tay-Sachs disease, Niemann-Pick disease, and Pompe disease ...
