CD38 (cluster of differentiation 38), previously known as T10, is a 46 kDa type II transmembrane glycoprotein (1). CD38 is expressed in both lymphoid and non-lymphoid tissue including in thymocytes, T and B lymphocytes, myeloid cells, natural killer cells, plasma cells, erythrocytes, and additionally in cells of the brain, pancreas, muscle, and bone (1,2). Structurally, CD38 is an "L"-shape which is formed by two separate domains connected by a three peptide-chain hinge region (2). The N-terminal domain is composed of five alpha-helices and two beta strands, while the C-terminal domain contains a four-stranded parallel beta-sheet and two long and two short alpha-helices (2). The CD38 molecule is located on chromosome 4 and is 300 amino acids (aa) in length with a theoretical molecular weight of 34 kDa that functions as both a receptor and an enzyme (1-6). As a receptor, CD38 interacts with its ligand CD31, which is largely expressed in endothelial cells (2-6). As an ectoenzyme, CD38 has a role in calcium signaling and is responsible for the conversion of nicotinamide adenine dinucleotide (NAD) into adenosine diphosphate-ribose (ADPR) or cyclic ADPR and the conversion of phosphorylated NAD (NADP) into nicotinic acid adenine dinucleotide phosphate (NAADP) (2-6).

As described above, CD38 is highly expressed in plasma cells and, as a result, is a target for treating multiple myeloma (MM), the cancer of white blood cells (4,6). The anti-CD38 monoclonal antibody daratumumab is one specific treatment for MM (4,6). Daratumumab has been shown to target MM cells through antibody-dependent cellular cytotoxicity and antibody dependent cellular phagocytosis (4). Additionally, CD38 has a potential role in neurodegenerative disorders and neuroinflammation as elucidated CD38's high expression in neurons, astrocytes, and microglia along with its enzymatic role in NAD degradation (3). Reduced NAD levels is a consequence of aging and occurs during neurodegeneration (3). Furthermore, murine studies have found that CD38 deletion inhibits neuroinflammation and neurodegeneration and therefore might be a potential therapeutic target (3). Similarly, CD38 inhibitors, like quercetin and luteolin, are used to treat age-related diseases and metabolic disorders (7).
