Final answer:
Apoptotic cells are cleared through recognition of abnormal cells by T-cells and binding of cellular receptors to the extracellular matrix. This helps maintain overall health and prevent uncontrolled cell proliferation.
Step-by-step explanation:
Apoptotic cells are cleared through various signals and mechanisms. One of the signals that clears apoptotic cells is the recognition of abnormal cells by immune cells called T-cells. If a T-cell receptor binds to self proteins, indicating an abnormal cell, it initiates apoptosis to eliminate the potentially dangerous cell.
Another signal for apoptotic cell clearance is the binding of cellular receptors to the extracellular matrix, which triggers a signaling cascade within the cell. If the cell moves away from the extracellular matrix, the signaling ceases and the cell undergoes apoptosis. These mechanisms of apoptotic cell clearance help maintain overall health and prevent uncontrolled cell proliferation.
