Immunological Surveillance is the Function of Activated Macrophages and Which

Question

Immunological surveillance is the function of activated macrophages and which of the following?
A) cytotoxic T cells
B) regulatory T cells
C) plasmocytes
D) NK cells
E) helper T cells

Accepted Answer

Immunological surveillance is the function of activated macrophages and natural killer (NK) cells, which can recognize and destroy abnormal cells such as virus-infected or cancerous cells. Cytotoxic T cells and helper T cells are involved in specific immune responses, while regulatory T cells suppress immune responses. Plasmocytes produce antibodies, but they do not directly participate in immunological surveillance.
