Hair growth in mice that lack the receptor wasn't inhibited by prostaglandin D2, suggesting that drugs that block GPR44 might help treat baldness, the researchers say.
The PGD2-related inhibition occurred through a receptor called GPR44, which is a promising therapeutic target for androgenetic alopecia in both men and women with hair loss and thinning.
Future studies, potentially testing topical treatments that may target GPR44, can determine whether targeting prostaglandins will benefit woman with AGA as well.
