IgD

IgD (/aɪˈdʒiːˈdiː/), or Immunoglobulin D, is one of the five classes of immunoglobulins known in mammals.

Etymology

The term "IgD" is derived from the word "Immunoglobulin", which is a type of protein that plays a crucial role in the immune response, and "D" which represents its classification in the series of immunoglobulins identified.

Function

IgD is primarily found on the surface of B cells, where it acts as a receptor for antigens. It plays a significant role in the induction of primary immune responses. However, the exact function of IgD is not fully understood and is a subject of ongoing research.
