Ligands that promote cell death are typically produced on the surface of cells of the immune system that recognize abnormal cells and target them for destruction.

Question

Quizplus · Accepted Answer

Ligands that promote cell death, such as Fas ligand (FasL), are indeed produced on the surface of immune cells, including T cells and natural killer (NK) cells. These ligands bind to their respective receptors on target cells, leading to apoptosis (programmed cell death) of the abnormal cells, which is a mechanism used by the immune system to eliminate infected, transformed, or otherwise diseased cells.
