Helper $T$-cells stimulate proliferation of other $T$-cells in immune response.

Vedclass · Answer

(A) The correct statement is that Helper $T$-cells stimulate the proliferation of other $T$-cells and $B$-cells in the immune response. $A$ is correct because Helper $T$-cells ($CD4^+$ cells) release cytokines that activate and stimulate the proliferation of cytotoxic $T$-cells and $B$-cells. $B$ is incorrect because opsonisation refers to the process of coating pathogens with antibodies to make them more susceptible to phagocytosis,not clumping (which is agglutination). $C$ is incorrect because Helper $T$-cells are activated,not deactivated,by antigen-presenting cells. $D$ is incorrect because Natural Killer $(NK)$ cells are part of the innate immune system,which provides non-specific defense,not specific defense.

Select the $CORRECT$ statement.
