General Information
Biological Significance
IL21 is a pleiotropic cytokine produced by CD4+ T cells in response to antigenic stimulation. Its action generally enhances antigen-specific responses of immune cells. The biological effects of IL21 include induction of differentiation of T-cells-stimulated-B-cells into plasma cells and memory B-cells, stimulation (in conjunction) with IL4 of IgG production, and induction of apoptotic effects in naïve B-cells and stimulated B-cells in the absence of T-cell signaling.
