Supplementary information

IgD also known as Immunoglobulin D serves as a distinct antibody isotype expressed primarily on the surface of B cells. It is involved in the initiation of immune responses. IgD has a molecular weight of approximately 180 kDa. The full form of IgD is Immunoglobulin D. It is expressed mainly in the respiratory system the tonsils and lymphoid tissues playing a pivotal role in the early stages of immunity. Researchers often perform IgD tests to study its mechanical aspects and influence on immune cell functionality.

Biological function summary

IgD contributes to the activation and differentiation of B lymphocytes and may influence antibody affinity maturation. This immunoglobulin is not known to form part of a larger complex but acts in conjunction with other immunoglobulins like IgM to regulate immune responses. The presence of IgD on B cells suggests its involvement in signaling processes which help B cells transition from immature to fully functional states impacting how the immune system responds to pathogens.

Pathways

IgD plays roles in immune system signaling and pathogen recognition. It appears in pathways such as B cell receptor signaling and participates in complex interactions with other proteins such as IgM and CD79 which are essential for transmitting activation signals. These pathways are important enabling the immune system to identify and respond to antigens effectively offering a first line of defense against infections.

IgD has associations with recurrent respiratory infections and IgD myeloma a rare form of plasma cell neoplasm. The malfunction or dysregulation of IgD can impact B cell development and lead to immune system disorders. In such cases IgD levels often measured through IgD tests may serve as important indicators for monitoring disease progression. Moreover elevated levels of IgD can coexist with proteins such as IgE particularly in allergy-related responses and play roles in certain immunodeficiency conditions.

Target data

Constant region of immunoglobulin heavy chains. Immunoglobulins, also known as antibodies, are membrane-bound or secreted glycoproteins produced by B lymphocytes. In the recognition phase of humoral immunity, the membrane-bound immunoglobulins serve as receptors which, upon binding of a specific antigen, trigger the clonal expansion and differentiation of B lymphocytes into immunoglobulins-secreting plasma cells. Secreted immunoglobulins mediate the effector phase of humoral immunity, which results in the elimination of bound antigens (PubMed : 20176268, PubMed : 22158414). The antigen binding site is formed by the variable domain of one heavy chain, together with that of its associated light chain. Thus, each immunoglobulin has two antigen binding sites with remarkable affinity for a particular antigen. The variable domains are assembled by a process called V-(D)-J rearrangement and can then be subjected to somatic hypermutations which, after exposure to antigen and selection, allow affinity maturation for a particular antigen (PubMed : 17576170, PubMed : 20176268). IgD is the major antigen receptor isotype on the surface of most peripheral B-cells, where it is coexpressed with IgM. The membrane-bound IgD (mIgD) induces the phosphorylation of CD79A and CD79B by the Src family of protein tyrosine kinases. Soluble IgD (sIgD) concentration in serum below those of IgG, IgA, and IgM but much higher than that of IgE. IgM and IgD molecules present on B cells have identical V regions and antigen-binding sites. After the antigen binds to the B-cell receptor, the secreted form sIgD is shut off. IgD is a potent inducer of TNF, IL1B, and IL1RN. IgD also induces release of IL6, IL10, and LIF from peripheral blood mononuclear cells. Monocytes seem to be the main producers of cytokines in vitro in the presence of IgD (PubMed : 10702483, PubMed : 11282392, PubMed : 8774350).
