apoptosis signaling pathway
The apoptosis signaling pathway is a process that cells use to safely self-destruct when they are damaged, old, or no longer needed. It involves a series of molecular signals that activate specific proteins called caspases, which systematically break down the cell's components. This controlled destruction prevents harmful substances from leaking out and triggers cleanup by the immune system. Apoptosis helps maintain healthy tissue function and prevents conditions like cancer. It can be initiated by internal signals from within the cell or external cues from other cells, ensuring that the body maintains balance and health.
