| Immunopharmacology Comments |
| CD37 is included in GtoImmuPdb as it is an immuno-oncology target that is being expoited for the development of novel therapeutics for the treatment of B cell malignancies, including non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukemia (CLL) [5,9,12,15]. |

| General Comments |
| The CD37 protein has 4 hydrophobic transmembrane domains, and it belongs to the tetraspanin (TSPAN) protein family (HGNC family ID 768) [2,13]. It is expressed solely by cells of the immune system, and is involved in the regulation of immune responses [7], cell-cell interactions, cell development, activation, growth and motility [2,13]. CD37 is found on normal and malignant B cells. It has been identified as a tumour suppressor that protects against B cell lymphomagenesis, an effect that is mediated by inhibiting the IL-6 pathway [4], and in support of this mechanism is the observation that in human lymphomas CD37 deficiency is a marker of poor prognosis [16]. |
