Which of the following statements correctly describes the function of a CD4 T-cell? (Level of difficulty: moderate) O CD4 T-cells are activated after interacting with any body cell, presenting antigen using a MHCI molecule. Once activated the CD4 cell releases cytokines to direct the required immune response. O CD4 T-cells are activated after interacting with a macrophage or dendritic cell, presenting antigen using a MHCII molecule. Once activated the CD4 cell will proliferate, interact with a B-cell and direct the immune response to the pathogen.
