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

Here, using colorectal cancer (CRC) as a model, we explored the gene expression of a panel of GPCRs in tumor live-imaging modalities, and displayed high efficiency when used to label complex 3D cellular systems such as tumor A2BAR as a potential pharmacological tool in CRC, using selective antagonists, finding a reduction in 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

PAR4 emerges as a potent oncogene, capable of inducing tumor generation. In addition to PH-Akt/PKB association, other PH-containing signal proteins such as Gab1 and Sos1 also associate with PAR4. in vitro and tumor development in vivo. treating EGFR/erbB-expressing tumors in cases of resistance to traditional therapies.

with various cancers, with some members of the RGS family being associated with liver cancer as well Gene Expression Omnibus (GEO) data, our analysis revealed that (a) RGS20 was strongly upregulated in tumor tissue compared with adjacent normal tissue of HCC patients; (b) RGS20 was strongly associated with some important clinical parameters such as alpha-fetoprotein and tumor grade in the HCC patients; (c) with some tumor-related signaling pathways and long intergenic non-coding RNAs (lincRNAs: LINC00511,

(CCR9), an organ-specific chemokine receptor, interacts with its exclusive ligand CCL25 to promote tumor Immunohistochemistry staining and RT–qPCR analyses were performed to detect the correlation of CCR9 expression and tumor progression-associated markers in SACC. The effect of CCL25 on the development of SACC in vivo was examined by a xenograft tumor model in nude

Both PAR4 and PAR2 are able to drive the association of methyltransferase EZH2 with β-catenin, culminating Indeed, EZH2 is found to be directly correlated with high PAR4-driven tumors, and is abundantly expressed in large tumors, whereas very little to almost none is expressed in small tumors.

high-impact mutations at cognate structural positions in class A G protein-coupled receptors expressed in tumors than effectors, mutations in different receptors could perturb signaling similarly so as to favor a tumor We hypothesized that somatic mutations in tumor samples may not be enriched within a single gene but that recurrent impactful oncogenic mutations perturb different GPCRs to subvert signaling and promote tumor

with transcriptomic analysis revealing that while the majority of cancer cells express multiple ORs, tumor cells associated with the nervous system express a single OR gene type (Kalra S. et. al 2020). directed towards an OR could either drive receptor inactivation or activation of the receptor to destroy tumor The chimeric antigen receptor T cell therapy could also be a way to target tumor cells expressing ectopic

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."

For instance, the expression of specific chemokine receptors in monocytes and macrophages indicates their previous studies, notably the work by Groot-Kormelink et al., which reported 165 GPCR mRNAs in alveolar macrophages contributions.Moreover, the study's findings on the unique expression of chemokine receptors in monocytes and macrophages
