GPR21 couples to the Gq family of G proteins and is expressed in macrophages. Studies of GPR21 knock-out mice indicated that GPR21 may be involved in promoting macrophage migration The aim of this study was to evaluate the role of GPR21 in human macrophages, analyzing (i) its involvement THP-1 cells were activated and differentiated into either M1 or M2 macrophages. Cell migration was detected by the Boyden chamber migration assay, performed on macrophages derived from

September 2022 Dynamics of tumor-associated macrophages in a quantitative systems pharmacology model As tumor-associated macrophages (TAMs) serve as major contributors to the immuno-suppressive tumor microenvironment We show that through proper calibration, the model captures the macrophage heterogeneity in the tumor

September 2022 Sweet taste receptor agonists attenuate macrophage IL‐1β expression and eosinophilic inflammation Autophagy deficiency in myeloid cells plays a causal role in eosinophilic CRS (ECRS) via macrophage IL autophagy‐enhancing agent, trehalose, or related sugar compounds, and the underlying mechanism focusing on macrophage Methods We investigated the therapeutic effects of trehalose and saccharin on macrophage IL‐1β production

expression has been directly challenged by a publication purporting ACKR1 expression in mouse BM by macrophages , but not erythroblasts and ECs, suggesting that macrophage ACKR1 engages its non-cognate ligand CD82 The reported ACKR1 expression by macrophages in Hur et al. relied on using commercial anti-ACKR1 antibody prompted us to investigate the specificity of FAB6695 and scrutinize the apparent ACKR1 expression in BM macrophages

GPR84 signaling promotes intestinal mucosal inflammation via enhancing NLRP3 inflammasome activation in macrophages expressed in myeloid cells that constitute the innate immune system, including neutrophils, monocytes, and macrophages Infiltrating GPR84+ macrophages are significantly increased in the colonic mucosa of both the UC patients activation, while the loss of GPR84 prevents the M1 polarization and properties of proinflammatory macrophages discovered by us, suppresses colitis by reducing the polarization and function of pro-inflammatory macrophages

/SST5 dimerization in rat GH3 as well as in human melanoma cells either expressing (A7) or lacking (M2 First, we observed the formation of endogenous SST5 homo-dimers in GH3, A7, and M2 cells. the PLA approach combined with epitope tagging, we detected homo-dimers of human SST2 in GH3, A7, and M2 A7), and octreotide but not pasireotide promoted hetero-dimerization in both A7 and M2 (+20.0 ± 11.8% and +44.1 ± 16.3% increase of PLA events in A7 and M2, respectively, P < 0.05 vs . basal).

Genome-scale CRISPR screening reveals that C3aR signaling is critical for rapid capture of fungi by macrophages "The fungal pathogen Histoplasma capsulatum (Hc) invades, replicates within, and destroys macrophages We demonstrated that whereas C3aR is dispensable for macrophage phagocytosis of bacteria and latex beads , it is critical for optimal macrophage capture of pathogenic fungi, including Hc, the ubiquitous fungal and uncover a novel and specific role for C3aR in macrophage recognition of fungi."
