Chemokine/chemokine receptor interactions play diverse roles in cell migration and homeostasis. Emerging evidence suggests that cancer cells co-opt chemokine networks for survival, proliferation, immune evasion, and metastasis. Most of the chemokine receptors are reported to be involved in tumor progression. Given their extensive implication in cancer progression, several chemokine receptor/lig...

understanding the molecular mechanisms in regeneration could help the stem cell therapists to improve the clinical practices and could be considered a major milestone in the translation of stem cell research to clinics. chemokines have been described as one of the most significant singling networks in stem cells homing and regeneration of damaged organs. cxcr4/cxcl12 has been known as a key pla...

objective(s):the limited homing potential of bone-marrow-derived mesenchymal stem cells (bm-msc) is the key obstacle in msc-based therapy. it is believed that chemokines and chemokine receptor interactions play key roles in cellular processes associated with migration. meanwhile, mscs express a low level of distinct chemokine receptors and they even lose these receptors on their surface after a...

The atypical chemokine receptor ACKR3 contributes to chemotaxis by binding, internalizing, and degrading the chemokines CXCL11 and CXCL12 to shape and terminate chemotactic gradients during development and immune responses. Although unable to trigger G protein activation, both ligands activate G protein-independent ACKR3 responses and prompt arrestin recruitment. This offers a model to specific...

Chemokine receptors are seven transmembrane-domain receptors belonging to class A of G-protein-coupled receptors (GPCRs). The receptors together with their chemokine ligands constitute the chemokine system, which is essential for directing cell migration and plays a crucial role in a variety of physiologic and pathologic processes. Given the importance of orchestrating cell migration, it is vit...

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...

Neuropeptides play an important role in the active communication between the nervous and immune systems. Substance P (SP) is a prominent neuropeptide involved in neurogenic inflammation and has been reported to exert various proinflammatory actions on inflammatory leukocytes including neutrophils. The present study further investigated the modulatory effect of SP (1 muM) on chemokine production...
