WebHigh density lipoprotein (HDL) is a major carrier of S1P, and studies of hearts in which selected S1P receptors have been inhibited implicate the S1P cargo of HDL in cardioprotection. Inhibition of S1P lyase, an endogenous enzyme that degrades S1P, also leads to cardioprotection. These observations have considerable relevance for future ... WebFeb 6, 2024 · Studies have demonstrated that S1P bound to albumin or HDL does not impact its ability to activate S1PRs, but rather creates a reservoir of S1P, keeping the S1P within circulation (reviewed by ). As total S1P is detected at higher concentrations in blood [ 33 ] and at lower concentrations within the bone [ 34 ], a concentration gradient is ...
