< GPCR News < GPCRs in Oncology and Immunology Expanding role of CXCR2 and therapeutic potential of CXCR2 Upregulation of CXCR2 is closely associated with the migration of neutrophils and monocytes. To date, many small-molecule CXCR2 antagonists have entered clinical trials, showing favorable safety According to the latest development and recent clinical progress of CXCR2 small molecule antagonists, we speculated that CXCR2 can be used as a biomarker and a new target for diabetes and that CXCR2 antagonists

< GPCR News < GPCRs in Oncology and Immunology Chemokine Cxcl1-Cxcl2 heterodimer is a potent neutrophil Here, we characterized the role for heterodimer and show that the Cxcl1-Cxcl2 heterodimer is a potent Chemokine-mediated neutrophil recruitment is determined by Cxcr2 receptor signaling, Cxcr2 endocytosis We have now determined heterodimer's Cxcr2 activity using cellular assays and Cxcr2 density in blood that the heterodimer binds glycosaminoglycans with higher affinity and more efficiently than Cxcl1 or Cxcl2

The team’s projects are devoted to the activation/function of CXCR4-ACKR3 (CXCR7) receptors of the CXCL12 of chemokines and their receptors, for which she made important breakthroughs regarding the CXCL12/CXCR4 In particular, FB contributed to the discovery that CXCL12 is the ligand for the CXCR4 receptor and can as a modulator of CXCL12/CXCR4 functions. ), and a smaller subgroup of atypical chemokine receptors (including the CXCR7/ACKR3). " Dr.

< GPCR News < GPCRs in Oncology and Immunology LPA1-mediated inhibition of CXCR4 attenuates CXCL12-induced CXC chemokine receptor 4 (CXCR4) and its ligand CXCL12, both of which are overexpressed in many cancers In our preliminary study, we identified LPA1 as a prospective CXCR4 interactor. , and β-arrestin recruitment, while CXCL12 binding to CXCR4 remained unaffected. In contrast, CXCR4 had no impact on LPA1-mediated signaling.

signaling and cancer cell migration Published date February 1, 2023 Abstract "C-X-C chemokine receptor 4 (CXCR4 Simultaneous activation of CXCR4 and HRH1 synergistically increases calcium flux in MDA-MB-231 cells that endogenously express CXCR4 and HRH1 but not in cells deficient in CXCR4 or HRH1. Costimulation of CXCR4 and HRH1 also significantly enhances CXCL12-induced MDA-MB-231 cell migration, of the CXCR4-HRH1 heteromer as a potential therapeutic target for anticancer therapy."

< GPCR News < GPCRs in Oncology and Immunology Distinct Activation Mechanisms of CXCR4 and ACKR3 Revealed their Conformational Landscapes Published date June 20, 2024 Abstract "The canonical chemokine receptor CXCR4 While CXCR4 couples to G proteins and directly promotes cell migration, ACKR3 is G protein-independent CXCR4 only responds to wild-type CXCL12 and is sensitive to mutation of the chemokine. To investigate the role of conformational dynamics in the distinct pharmacological behaviors of CXCR4

GPCRs in Oncology and Immunology The GPCR adaptor protein Norbin controls the trafficking of C5aR1 and CXCR4 Here, we identify C5aR1 and CXCR4 as direct Norbin interactors and used mice with myeloid-Norbin deficiency to investigate the role of Norbin in the trafficking of endogenous C5aR1 and CXCR4 in primary neutrophils internalisation of CXCR4. Our study demonstrates how Norbin suppresses C5aR1 and CXCR4 function in neutrophils and increases our
