The cell-mediated immunity that destroys virally infected cells involves
A) cytotoxic T cells.
B) natural killer cells.
C) helper T cells.
D) macrophages.
E) B cells.

Question

Quizplus · Accepted Answer

Cytotoxic T cells are responsible for identifying and destroying virally infected cells in cell-mediated immunity.

Answer: B 
 Natural killer cells also play a role in cell-mediated immunity by attacking virally infected cells and tumors.

Answer: C 
 Helper T cells assist in the activation and proliferation of cytotoxic T cells, making them essential for cell-mediated immunity against viral infections.

Answer: D 
 Macrophages play a role in immune response by engulfing and digesting foreign material, including virally infected cells. However, they primarily function in the early stages of immune response and are not directly involved in cell-mediated immunity against viruses.

Answer: E 
 B cells are responsible for antibody-mediated immunity and are not directly involved in cell-mediated immunity against viruses.
