Abstract

The potent lipid mediator sphingosine-1-phosphate (S1P) is produced inside cells by two closely related kinases, sphingosine kinase 1 (SPHK1) and SPHK2, and has emerged as a crucial regulator of immunity. Many of the actions of S1P in innate and adaptive immunity are mediated by its binding to five G protein-coupled receptors, designated S1PR1-5, but recent findings have also identified important roles for S1P as a second messenger during inflammation. In this Review, we discuss recent advances in our understanding of the roles of S1P receptors and describe the newly identified intracellular targets of S1P that are crucial for immune responses. Finally, we discuss the therapeutic potential of new drugs that target S1P signalling and functions.

  • S1P mainly functions as an extracellular ligand for G protein-coupled receptors and as a transcriptional regulator in the nucleus.

    “S1P, a product of SphK2, mainly functions as an extracellular ligand for G protein-coupled receptors and as a transcriptional regulator in the nucleus (49).”

    From Nuclear SphK2/S1P signaling is a key regulator of ApoE production and Aβ uptake in astrocytes (2024) · cites this paper as [49]

    The Abstract describes S1P as an agonist of G protein-coupled S1P receptors, and “Regulation of histone deacetylases by S1P” describes nuclear S1P produced by SPHK2 influencing transcription through HDAC1 and HDAC2. The paper also describes other intracellular actions, including regulation of TNFR signalling, so it does not establish that the two functions named are S1P’s main functions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
