extrinsic apoptosis pathway
The extrinsic apoptosis pathway is a process by which cells can be directed to self-destruct when damaged or abnormal. It begins when external signals, often from immune cells or specific molecules, bind to receptors on the cell surface. This triggers a cascade that activates enzymes called caspases, which systematically dismantle the cell's components. This pathway helps the body eliminate infected, damaged, or cancerous cells, maintaining overall health and tissue balance. It’s a vital part of the immune system’s ability to control cell growth and prevent disease.
