Class switching (or isotype switching) is a genetic rearrangement in activated B cells that changes the constant region (Fc) of the antibody heavy chain from one isotype (e.g., IgM) to another (e.g., IgG, IgA, or IgE). This changes the antibody's effector functions without altering its antigen-binding specificity.
