WebIn conclusion, SPHK activity and S1PR signaling emerge as important regulators of macrophage polarization, although the impact of some components of this machinery such as SPHK2, S1PR4, and S1PR5 needs to be tested in the future. Since macrophages are implicated in the development of inflammatory diseases, altered functional macrophage ... WebMay 18, 2024 · SphK is a conserved enzyme, bearing resemblance to other mammalian, eukaryotic, and prokaryotic lipid kinases ( 2 ). In humans, two SphK enzymes exist: sphingosine kinase 1 (SphK1) and sphingosine kinase 2 (SphK2). The phosphorylation of sphingosine to S-1P is done mostly through the activity of SphK1 ( 24 ).

No enzymatic activity could be detected in serum-containing media, even when it was concentrated. Instead, it was possible to detect a low SphK activity in 40-fold-concentrated serum-free medium that had been conditioned by maintaining cells in culture for 24 h.
