Chemokines are a family of small proteins involved in cellular migration and intercellular communication. Although the chemokines and their receptors are located throughout the brain, they are not distributed uniformly. Among the chemokines and their receptors that are arrayed disproportionately in glia and neurons are monocyte chemotactic protein-1/CC chemokine ligand 2 (CCL2), stromal cell-de...
PURPOSE Ascitic disease is a common occurrence in human ovarian cancer, but it is unclear how the cellular composition of ascitic fluid is determined. Because chemokines can determine host cell infiltration in solid ovarian cancer, we assessed CC chemokine protein and CC chemokine receptor expression in ovarian cancer ascites. EXPERIMENTAL DESIGN We used reverse transcription-PCR and RNase pr...
Cytokine and chemokine gradients are central to the directed movement of cells in both homeostatic and pathological processes. Most cancers have a complex chemokine network which can influence immune responses to the tumor, direct the extent and cellular composition of the leukocyte infiltrate and also play a role in angiogenesis. Tumor cells can also hijack the chemokine system and gain expres...
Viruses encode proteins that disrupt chemokine responses. The murine gammaherpesvirus 68 gene M3 encodes a chemokine binding protein (vCKBP-3) which has no sequence similarity to chemokine receptors but inhibits chemokine receptor binding and activity. We have used a panel of CXCL8 analogs to identify the structural requirements for CXCL8 to bind to vCKBP-3 in a scintillation proximity assay. O...
Chemokine receptors comprise a large family of seven transmembrane domain G protein-coupled receptors differentially expressed in diverse cell types. Biological activities have been most clearly defined in leukocytes, where chemokines coordinate development, differentiation, anatomic distribution, trafficking, and effector functions and thereby regulate innate and adaptive immune responses. Pha...
Leucocyte migration is essential for robust immune and inflammatory responses, and plays a critical role in many human diseases. Chemokines, a family of small secreted protein chemoattractants, are of fundamental importance in this process, directing leucocyte trafficking by signalling through heptahelical G-protein-coupled receptors expressed by the migrating cells. However, several mammalian ...
Acute myeloid leukemia (AML) is an aggressive and heterogeneous bone marrow malignancy, the only curative treatment being intensive chemotherapy eventually in combination with allogeneic stem cell transplantation. Both the AML and their neighboring stromal cells show constitutive chemokine release, but chemokines seem to function as regulators of AML cell proliferation only for a subset of pati...
