Expression and regulation of chemokine receptors in human natural killer cells.
Using flow cytometric and RNase protection assays, this study examined the expression of chemokine receptors in nonactivated natural killer (NK) cells and compared this expression with NK cells activated with interleukin (IL)-2, which either adhered to plastic flasks (AD) or did not adhere (NA). None of the NK cell subsets expressed CXCR2, CXCR5, or CCR5. The major differences between these cel...
متن کاملChemokine receptor expression and function in CD4+ T lymphocytes with regulatory activity.
We have investigated the chemokine receptor expression and migratory behavior of a new subset of nickel-specific skin-homing regulatory CD4(+) T cells (Th(IL-10)) releasing high levels of IL-10, low IFN-gamma, and undetectable IL-4. These cells inhibit in a IL-10-dependent manner the capacity of dendritic cells to activate nickel-specific Tc1 and Th1 lymphocytes. RNase protection assay and FACS...
متن کاملComparative Analysis of Expression of Chemokoine Receptors CXCR4, CXCR6, CCR1 and CX3CR in Human Adipose-Drived Mesenchymal Stem Cell with Valproic Acid
Introduction: Chemokine receptors are found on the surface of stem cells. There have been 19 distinct chemokine receptors described in mammals. Chemokines are major players in migration and homing. Therefore, changes in their levels or function can help us to increase the migratory potential of these cells. Valproic acid differs in structure from other drugs in common use. The way in which Va...
متن کاملChemically primed bone-marrow derived mesenchymal stem cells show enhanced expression of chemokine receptors contributed to their migration capability
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...
متن کاملUnique Chemotactic Response Profile and Specific Expression of Chemokine Receptors Ccr4 and Ccr8 by Cd4+Cd25+ Regulatory T Cells
Chemokines dictate regional trafficking of functionally distinct T cell subsets. In rodents and humans, a unique subset of CD4(+)CD25(+) cytotoxic T lymphocyte antigen (CTLA)-4(+) regulatory T cells (Treg) has been proposed to control peripheral tolerance. However, the molecular basis of immune suppression and the trafficking properties of Treg cells are still unknown. Here, we determined the c...
