Final answer:

The Fas ligand and Fas protein receptor promote the aggregation of procaspase-8, leading to cell apoptosis. This process is important for eliminating infected cells and pathogens.

Step-by-step explanation:

The Fas ligand and Fas protein receptor play a role in promoting the aggregation of procaspase-8, which then becomes activated and leads to apoptosis, or cell death. Fas ligand is a molecule expressed on cytotoxic T cells and NK cells, and it binds to the Fas molecule on target cells, inducing apoptosis. This process is important for eliminating infected cells and pathogens.



During apoptosis, active caspases, such as caspases X, Y, and Z, are released. Caspases are proteolytic enzymes that digest cellular proteins.



In the context of the immune system, NK cells respond to chemical signals and express Fas ligand. When Fas ligand binds to Fas on the surface of an infected cell, it sends apoptotic signals, resulting in the killing of the cell and the pathogen within it.
