Data by Arne Hansen et a l has introduced a sensitive method for detecting GPCR mRNAs in human immune cells The study reports that human white blood cells express an average of 160 GPCR mRNAs, ranging from 123 , suggesting a potential role in regulating red blood cell production and offering a novel avenue for Additionally, the study identified unique expression patterns of GPCRs in different immune cell types , including B cells, CD4+ T cells, CD8+ T cells, natural killer (NK) cells, and dendritic cells.

August 2022 "Oxysterols induce the migration of B-lymphocytes and dendritic cells to interfollicular oxysterol binding site and the Gαi interface attenuate G protein signaling and abolish oxysterol-mediated cell

The immune system depends on chemokines to direct cell migration during immune surveillance and inflammation Scavenging allows cells to continuously migrate by remaining responsive to chemokines, it dampens the Interestingly, in monocytes and dendritic cells exposed to treatments mimicking inflammation, CCR1, CCR2 , and CCR5 switch purely to scavenging (D'Amico G. et al. 2000), becoming incapable of promoting cell migration, a phenomenon which is likely to be mediated by changes in the cell motility machinery with

formation in human intestinal dendritic cells Published date October 29, 2024 Abstract "The intestinal lumen is rich in gut microbial metabolites that serve as signaling molecules for gut immune cells. cells (cDC1s) in the lamina propria of the human intestine. Using human induced pluripotent stem cell-derived cDC1s and a monolayer human gut organoid coculture dendrites (TED).

Lastly, we provide evidence that complete GRK deficiency impairs dendritic cell homeostasis, which unexpectedly results from defective dendritic cell differentiation and maturation in vitro and in vivo . ; GRK; T cells; dendritic cells; immune cell trafficking; leukocytes; neutrophils.
