Explanation:
Detailed explanation-1: -IL-2 can influence these effector activities in CD8+ T cells by inducing the expression of IFN- (49, 50), TNF-, and lymphotoxin (51), by stimulating expression of the cytolytic effector molecules granzyme B (34, 44, 52) and perforin (34, 52), and by promoting effective target cell killing (34, 44).
Detailed explanation-2: -Or (D) the B cell releases interleukin 2. This figure is showing us a B cell. The B cell receptor, shown in green, has bound to an antigen on the surface of the bacterium. This signals to the B cell to engulf the pathogen and break it down.
