Figure 3. B-cell, T-cell and APC Responses.

Figure 3

Recognition of infecting agent by antigen presenting cells (APC) and subsequent interaction with T-cells. Activation of B-cells result in antibody production and long-lived memory B-cells. Activation of CD4+ T-cells via MHCII pathway produces Th1, Th2 or Th17 depending on the cytokine stimulation. Recognition of infecting agent via the MHCI pathway activates cytotoxic CD8+ T-cells that directly attack the infecting cell.
