Clinical Significance:
IgD, together with IgM, are the major immunoglobulins expressed on the surface of B cells where it seems they may operate as mutually interacting antigen receptors for the control of lymphocyte activation and suppression. IgD is expressed in normal and neoplastic mantle cells and in CLL/SLL. It may be useful in the evaluation of marginal zone lymphocyte proliferations in extranodal tissue.
