Immunopharmacology Comments
CS1 is a member of the signalling lymphocyte activation molecule (SLAM) receptor family. CS1 is a membrane glycoprotein primarily expressed on plasma cells. Homophilic interaction (i.e. interaction with itself) of CS1 induces B cell proliferation and autocrine cytokine secretion, thus playing a role in various immune functions.

CS1 is a validated molecular target for the development of novel immunotherapeutics with the potential to treat MM, a malignant disease of plasma cells which remains incurable despite advances in treatment (such as bortezomib, lenalidomide and immunotherapies in clinical trial). Indeed, a combination therapy containing the anti-CS1 mAb elotuzumab (elotuzumab + lenalidomide + dexamethasone), was FDA approved for MM in 2015. CS1 expression is also elevated in patients with systemic lupus erythematosus (SLE) [1], suggesting that this condition may also benefit from clinical CS1-targeted inhibition.
