Final answer:

CD8 T cells produce cytotoxins such as d) perforin, granzymes, and granulysin to induce apoptosis in pathogen-infected cells, differentiating them from helper T cells that release cytokines.

Step-by-step explanation:

The cytotoxins produced by CD8 T cells are perforin, granzymes, and granulysin. These molecules are crucial for the cytotoxic function of CD8 T cells as they induce apoptosis in pathogen-infected cells.

When a CD8 T cell, also known as a cytotoxic T cell, interacts with an MHC I-epitope complex on the surface of an infected cell, it releases these cytotoxic molecules to kill the infected cell and prevent the spread of infection.

CD8 T cells are distinct from helper T cells (CD4 T cells), which release cytokines to stimulate other immune cells. The relationship between cytotoxic T cells and other parts of the immune system.

Like natural killer cells and antibodies, is complex and coordinated to ensure efficient immune responses against pathogens.
