Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cell-mediated immunity is a type of acquired immunity. This is the immunity one develops throughout life. Which of the following types of cells are mostly involved in cell-mediated immunity?
A
T cells
B
B cells
C
erythrocytes
D
neutrophils
Explanation: 

Detailed explanation-1: -Cell-mediated immunity is directed primarily at microbes that survive in phagocytes as well as those that infect non-phagocytic cells.

Detailed explanation-2: -Acquired immunity includes both humoral immunity, as well as cell-mediated immunity.

Detailed explanation-3: -Cell-mediated immunity is largely based on the function of T-helper (Th) lymphocytes. These lymphocytes (CD4+; T-helper cells) mediate proliferation and differentiation of various immune-competent cells via their release of various cytokines (e.g., IL-2, IL-4, IL-5, IL-6).

Detailed explanation-4: -The correct answer is a) Plasma cells. All of the following are components of cell-mediated immunity except plasma cells.

Detailed explanation-5: -There are two types of adaptive responses: the cell-mediated immune response, which is carried out by T cells, and the humoral immune response, which is controlled by activated B cells and antibodies.
