B cells, type 2 helper T cells, antibodies, mast cells, and eosinophils are involved in the humoral immune response. Type 1 helper T cells and cytoxic T-cells are involved in cell-mediated immune response. WebIgMs are the major class of antibodies that are secreted by B cells in response to the first exposure to an antigen—the primary antibody response. When an antigen binds to an IgM molecule, it activates the complement system and neutralizes pathogens. The functions of IgD antibodies are not well understood but seem to resemble those of IgM.
