What is the Effector Function of CD4⁺ Cells

Question

What is the effector function of CD4⁺ cells?
A)production of interleukin-2
B)response to MHC I-peptide complexes
C)The cytotoxic killing of infected cells.
D)response to MHC II-peptide complexes
E)Stimulation of dendritic cells.

Accepted Answer

CD4⁺ cells produce and secrete cytokines, including interleukin-2, that help orchestrate and stimulate the immune response by activating other immune cells. They primarily respond to peptide antigens presented by MHC II complexes on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and do not have cytotoxic killing capabilities like CD8⁺ cells.
