Question

What do lysosomes do in the immune system?

Answer 1

Lysosomes:

1. Lysosomes are said to be the membrane-bound organelles responsible to invade and destroy pathogens entering inside the cells.
2. Autophagy and phagocytosis are seen in both adaptive and innate immunity.
3. They are the chief catabolic subcellular structures that recycle and are responsible for the degradation of intracellular as well as extracellular content.
4. A macrophage invades a potential pathogen bacteria and engulfs it by fusing with a lysosome in a cell to destroy the pathogen.
5. It destroys harmful particles through apoptosis which is programmed cell death.
6. Lysosomes contain hydrolytic enzymes which include nucleases, proteases, phosphatases, glycosidases, lipases, phospholipases, and sulfatases.
