lysosome
- n an organelle found in the cytoplasm of most cells (especially in leukocytes and liver and kidney cells)
- The lysosome's job is to defend the cell from hostile viruses, bacteria and other materials by engulfing the invaders and dissolving them with its enzymes.
- How they work on some cells at some times seems clear: the cortisone group of hormones strengthens the lysosome membrane, making it less likely to spill out its enzymes.
