Immunopharmacology Comments
Sphingomyelin synthase 2 (SMS2) is a promising therapeutic target for chronic inflammation-associated diseases, such as atherosclerosis, fatty liver and insulin resistance. Since downregulation of SMS2 activity results in protective effects against obesity, atherosclerosis and diabetes, selective SMS2 inhibitors are being explored as novel alternatives for the treatment of such metabolic diseases [1].
