INTRODUCTION: Fingolimod was the first oral therapy approved for the treatment of relapsing-remitting multiple sclerosis (RRMS). Due to its action on cardiac sphingosine 1-phosphate receptors, fingolimod is leading to a transient decrease in heart rate (HR) and the occurrence...

BACKGROUND: Bone marrow adipocyte (BMA), closely associated with bone degeneration, shares common progenitors with osteoblastic lineage. However, the intrinsic mechanism of cells fate commitment between BMA and osteogenic lineage remains unclear.METHODS: Gene Expression Omnibus (GEO) dataset GSE107789 publicly available...

Blood-thirsty: S1PR5 and TRM.

The Journal of experimental medicine

Hallisey VM, Schwab SR.
PMID: 34714328
J Exp Med. 2022 Jan 03;219(1). doi: 10.1084/jem.20211971. Epub 2021 Oct 29.

In this elegant study, Evrard et al. (2021. J. Exp. Med.https://doi.org/10.1084/jem.20210116) find that sphingosine 1-phosphate receptor 5 (S1PR5) powerfully impairs tissue-resident memory T cell (TRM) formation, and that tissue-derived TGF-β limits S1pr5 expression by infiltrating T cells.

There is substantial evidence for a role in cancer of the bioactive lipid sphingosine 1-phosphate (S1P), the enzyme sphingosine kinase 1 (that catalyses S1P formation) and S1P-specific G protein-coupled receptors. This perspective highlights recent findings demonstrating that sphingosine kinase...
