What Cells Directly Terminate Antigens

Question

What cells directly terminate antigens?
A) suppressor T cells
B) helper T cells
C) cytotoxic T cells
D) cytotoxic B cells

Accepted Answer

Cytotoxic T cells directly terminate antigens by recognizing and binding to antigen-presenting cells that are displaying the antigen. The cytotoxic T cell then releases enzymes that destroy the infected cell, thus eliminating the source of the pathogen. Suppressor T cells regulate the immune response, helper T cells assist in activating other immune cells, and there is no known cell called a cytotoxic B cell.
