CD38 is a multifunctional ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose in addition to synthesis of NAADP from NADP+.[5] These reaction products are essential for the regulation of intracellular Ca2+.[6]
The loss of CD38 function is associated with impaired immune responses, metabolic disturbances, and behavioral modifications including social amnesia possibly related to autism.[6][7]
The CD38 protein is a marker of cell activation. It has been connected to HIV infection, leukemias, myelomas, solid tumors, type II diabetes mellitus and bone metabolism, as well as some genetically determined conditions.
CD38 produces an enzyme which regulates the release of oxytocin within the central nervous system.[7]
Increased expression of CD 38 is an unfavourable diagnostic marker in chronic lymphocytic leukemia and is associated with increased disease progression.[10]
CD38 has been used as a prognostic marker in leukemia.[11] CD38 is also used as a target for daratumumab (Darzalex), a medicine that has been approved for the treatment of multiple myeloma.
The use of Daratumumab can interfere with pre-Blood transfusion tests, as CD38 is weakly expressed on the surface of erythrocytes. Thus, a screening assay for irregular antibodies against red blood cell antigens or a direct immunoglobulin test can produce false-positive results.[12] This can be sidelined by either pretreatment of the erythrocytes with dithiothreitol (DTT) or by using an anti-CD38 antibody neutralizing agent, e.g. DaraEx.
A gradual increase in CD38 has been implicated in the decline of NAD+ with age.[13][14] Treatment of old mice with a specific CD38 inhibitor, 78c, prevents age-related NAD+ decline.[15]
