The immune system depends on chemokines to direct cell migration during immune surveillance and inflammation However, an imbalance in the chemokine system can also contribute to various diseases, such as inflammatory In all these situations, chemokines interact with seven-transmembrane chemokine-type G protein-coupled In humans there are approximately 45 chemokines, 19 chemotactic or G-protein coupled chemokine receptors Indeed, ACKRs behave as scavenging “decoys” in order to either limit chemokines spatial availability

The chemokine system exhibits great versatility, with more than 50 chemokines interacting with over 20 receptor-chemokine complexes and revealing the diverse and multifaceted nature of the chemokine receptor Chemokine Binding Mode – from CRS1 to CRS3 Chemokines possess a conserved tertiary structure known as This structural variation may explain why chemokine receptors typically recognize chemokines from only with deep binding, CC/CXC chemokines with shallow binding near TM5, and CX3C chemokines with shallow

The chemokine receptor system is implicated in a wide range of inflammatory, autoimmune and infectious The involvement of chemokines and their receptors in several aspects of cancer biology, represents a Therefore, an alternative approach is to make use of chemokine receptors redundancy and the fact that different chemokine receptors are overexpressed and promote cancer progression, and use promiscuous In the chemokine-receptor system, different chemokines are able to activate different pathways, which

< GPCR News < GPCRs in Oncology and Immunology Chemokine Physiology in Cancer Published date November 1, 2022 Abstract Chemokines are chemotactic cytokines whose canonical functions govern movement of receptor Chemokines are a physiologic system that is finely tuned by ligand and receptor expression, ligand or In this article we review current literature on the diversity of chemokine ligands and their cellular Facets of chemokine physiology across discrete cancer immune phenotypes are contrasted to existing chemokine-centered

< GPCR News < GPCRs in Oncology and Immunology Chemokine N-terminal-derived peptides differentially regulate signaling by the receptors CCR1 and CCR5 Published date November 23, 2023 Abstract "Inflammatory chemokines are often elevated in disease settings, where the largest group of CC-chemokines are the macrophage MIP chemokines, such as CCL3 and CCL5 are processed at the N-terminus, which influences signaling in In conclusion, chemokine N-termini can be mimicked to produce small CCR1-selective agonists, as well

cytarabine, G-CSF, and mitoxantrone in untreated AML Published date September 12, 2023 Abstract "CC chemokine However, it was unclear how chemokine ligands, activators and antagonists recognize hCCR3, and quantitative The study results indicate chemokines interact with hCCR3 at low concentrations, and reversible hCCR3 Moreover, a quantitative evaluation of hCCR3 chemokine activators and their antagonists was carried out This offers a novel approach to quantitatively evaluate chemokine-receptor activation and antagonism
