2024年12月24日 · CXCR1 (C-X-C Motif Chemokine Receptor 1) is a Protein Coding gene. Diseases associated with CXCR1 include Human Immunodeficiency Virus Type 1 and Acute Pyelonephritis. Among its related pathways are Class A/1 (Rhodopsin-like receptors) and GPCR downstream signalling.

CXCR1 and CXCR2 are closely related receptors that recognize CXC chemokines that possess an E-L-R amino acid motif immediately adjacent to their CXC motif. CXCL8 (otherwise known as interleukin-8) and CXCL6 can both bind CXCR1 in humans, while all other ELR-positive chemokines, such as CXCL1 to CXCL7 bind only CXCR2.

CXCR1 correlates to poor outcomes of EGFR-TKI against advanced non-small cell lung cancer by activating chemokine and JAK/STAT pathway. Conformational plasticity and dynamic interactions of the N-terminal domain of the chemokine receptor CXCR1.

2023年7月11日 · Here, we solve the structure of CXCR1 complexed with CXCL8 and cognate G-proteins using cryo-EM, showing the detailed interactions between the receptor, the chemokine and Gαi protein. Unlike the...

2020年5月19日 · In our hands, CXCR1 and CXCR2 agonists proved to be the major mediators of cancer-promoted NETosis. NETs wrap and coat tumor cells and shield them from cytotoxicity, as mediated by CD8 + T cells and natural killer (NK) cells, by obstructing contact between immune cells and the surrounding target cells.

2015年10月30日 · Both CXCR1 and CXCR2 play a pivotal role in innate immune responses by regulating the recruitment in particular of neutrophils, but also of monocytes, dendritic cells, natural killer cells, and mast cells to sites of infected and damaged and/or inflamed tissue.

Interleukin 8 receptor, alpha is a chemokine receptor. This name and the corresponding gene symbol IL8RA have been replaced by the HGNC approved name C-X-C motif chemokine receptor 1 and the approved symbol CXCR1. It has also been designated as CD181 (cluster of differentiation 181).

2023年2月16日 · CXCR1 is becoming more well known for its role as a cancer stem cell identifier and therapeutic target. This review elucidates the role of the CXCR1 axis as a CSC marker in several solid tumors and discusses the utility of CXCR1 as a therapeutic target.

CXCL8 (interleukin-8) interacts with two receptors, CXCR1 and CXCR2, to activate leukocytes. Upon activation, CXCR2 internalizes very rapidly relative to CXCR1 (∼90% versus ∼10% after 5 min).

2023年9月14日 · Here we reported that compared with healthy controls, the level of CXCR1 was aberrantly increased in multiple sclerosis (MS) patients. Knockout of CXCR1 not only ameliorated disease severity in...
