Question

The major function of CD8 T cells is to kill cells that have been infected by pathogens, such as bacteria and viruses. CD8 T cells are frequently referred to as T killer or cytotoxic T lymphocytes (CTL). The cell killed by a CTL is known as a target. An important pathway of target cell killing occurs via the interaction of the molecule Fas ligand on the activated CTL with Fas on the target cell. Fas is a ligand associated with what receptor family?

CEA
AFP
TNF
MAGE
Ras

Answer 1

The Fas ligand on activated cytotoxic T cells interacts with the Fas receptor on target cells, which belongs to the death receptor family.

Step-by-step explanation:

The molecule Fas ligand on activated cytotoxic T cells interacts with the Fas receptor on target cells. Fas is associated with the apoptotic signaling pathway and belongs to the death receptor family. When Fas ligand binds to Fas, it triggers a signaling cascade that leads to the death of the target cell through apoptosis.
