Activity summary

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.

Associated diseases and disorders

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.
