Background: CRTH-2

GPR44, or G-protein coupled receptor 44, is also designated as CRTH2 and CD294. GPR44 is expressed specifically on CD4+ Th2 cells and type 2 cytotoxic effector cells (1). GPR44 is a prostaglandin D2 receptor PGD2 and has some similar functions to other chemokines exerting chemotaxis of Th2 cells as well as eosinophils and basophils (2). Interestingly inhibition of hair growth by PGD2 is through GPR44 so the thought is that inhibition of GPR44 may also eliminate hair-loss or balding effects of PGD2 . This implies that inhibitors to GPR44 could be the new Rogaine(?) (3, 4). GPR44 is thought to be important in allergic diseases, including asthma, and several companies are already testing drugs that block GPR44 in clinical trials to treat these diseases (4).
