Antagonizing S1P<sub>3</sub> Receptor with Cell-Penetrating Pepducins in Skeletal Muscle Fibrosis
S1P is the final product of sphingolipid metabolism, which interacts with five widely expressed GPCRs (S1P<sub>1-5</sub>). Increasing numbers of studies have indicated the importance of S1P<sub>3</sub> in various pathophysiological processes. Recently, we have identified a pe...
