A leukocyte homologue of the IL-8 receptor CXCR-2 mediates the accumulation of macrophages in atherosclerotic lesions of LDL receptor-deficient mice. [PDF]
Chronic macrophage-mediated inflammation is central to atherosclerosis. A role of the monocyte chemotactic and activating C-C chemokine JE/monocyte chemotactic protein-1 has been proposed. However, the human C-X-C chemokines growth-regulated oncogene (GROalpha) and IL-8, and their shared receptor, CXCR-2, also can be expressed at sites of chronic ...

Expression and functional activity of CXCR-4 and CCR-5 chemokine receptors in human thymocytes
SummaryIn this paper we addressed the expression of the HIV co-receptors CXCR-4 and CCR-5 in human thymocytes by phenotypic, molecular and functional approaches. Cytofluorimetric analysis disclosed that CXCR-4 was constitutively expressed by freshly isolated thymocytes (~10 000 molecules/cell in about 30% of thymocytes); the receptor was endowed with ...

The CXC-Chemokine Neutrophil-Activating Peptide-2 Induces Two Distinct Optima of Neutrophil Chemotaxis by Differential Interaction With Interleukin-8 Receptors CXCR-1 and CXCR-2 [PDF]
AbstractThe CXC-chemokines interleukin-8 (IL-8), neutrophil-activating peptide-2 (NAP-2), and melanoma growth-stimulatory activity (MGSA) are chemoattractants with high selectivity for neutrophils. Although IL-8 has been shown to act as an extremely potent mediator, reports on NAP-2 and MGSA are still contradictory. Here we show for the first time that

Preferential Loss of CXCR-2 Receptor Expression and Function in Patients Who Have Undergone Trauma [PDF]
In response to traumatic injury or infection, human neutrophils are directed to the site of injury or infection by CXC chemokines that signal via 2 receptors, CXCR-1 and CXCR-2. In vitro studies have shown preferential loss of CXCR-2 expression and function after exposure to interleukin 8, N-formyl-methionyl-leucyl-phenylalanine (fMLP), C5a, and tumor ...

CXC Chemokines in the Pathogenesis of Pulmonary Disease and Pharmacological Relevance
Chemokines and their receptors play important roles in the pathophysiology of many diseases by regulating the cellular migration of major inflammatory and immune players.

Chemokine Receptors CXCR-1/2 Activate Mitogen-activated Protein Kinase via the Epidermal Growth Factor Receptor in Ovarian Cancer Cells [PDF]
Ovarian cancer typically disseminates widely in the abdomen, a characteristic that limits curative therapy. The mechanisms that promote ovarian cancer cell migration are incompletely understood. We studied model SK-OV-3 ovarian cancer cells and observed robust expression of the alpha chemokine receptors CXCR-1 and CXCR-2. Interleukin-8 (IL-8) treatment

Spatio-temporal regulation of concurrent developmental processes by generic signaling downstream of chemokine receptors [PDF]
Chemokines are secreted proteins that regulate a range of processes in eukaryotic organisms. Interestingly, different chemokine receptors control distinct biological processes, and the same receptor can direct different cellular responses, but the basis ...

Use of Murine CXCR-4 as a Second Receptor by Some T-Cell-Tropic Human Immunodeficiency Viruses [PDF]
ABSTRACTThe human CXCR-4 molecule serves as a second receptor for primary, T-cell-tropic, and laboratory-adapted human immunodeficiency virus type 1 (HIV-1) isolates. Here we show that murine CXCR-4 can support the entry of some of these HIV-1 isolates.
