________ Confer Cell-Mediated Immunity on the Body Tissues They Defend

Question

________ confer cell-mediated immunity on the body tissues they defend.
A) Helper T cells
B) NK cells
C) Regulatory T cells
D) B cells
E) Cytotoxic T cells

Accepted Answer

Cytotoxic T cells are a type of white blood cell that specialize in attacking and destroying cells that have become infected by viruses or other intracellular pathogens, as well as cancer cells. They confer cell-mediated immunity by recognizing and binding to specific antigenic peptides presented on the surface of infected or cancerous cells, and then releasing cytotoxic compounds such as perforin and granzyme to induce cell death. This process helps to limit the spread of pathogens and prevent the development of malignant tumors in the body's tissues.
