The chemokine receptor CXCR3 is a G protein-coupled receptor found predominantly on T cells that is activated by three ligands as follows: CXCL9 (Mig), CXCL10 (IP-10), and CXCL11 (I-TAC). Previously, we have found that of the three ligands, CXCL11 is the most potent inducer of CXCR3 internalization and is the physiologic inducer of CXCR3 internalization after T cell contact with activated endot...

Transendothelial migration is a pivotal step before the dissemination of tumor cells into the blood circulation. Related researches about the crosstalk between tumor cells and endothelial cells could contribute to understanding the mechanism of transendothelial migration. Cumulative studies showed that CD133 was an important marker for cancer stem cells. In our research, a co-culture system was...

Chemokines and their receptors play key roles in leukocyte trafficking and are also implicated in cancer metastasis to specific organs. Here we show that mouse B16F10 melanoma cells constitutively express chemokine receptor CXCR3, and that its ligands CXCL9/Mig, CXCL10/IP-10, and CXCL11/I-TAC induce cellular responses in vitro, such as actin polymerization, migration, invasion, and cell surviva...

OBJECTIVE To compare multiple serum markers for their ability to detect active disease in patients with GCA and in those with PMR. METHODS Twenty-six markers related to immune cells that may be involved in GCA and PMR were determined by ELISA and multiplex assay in the serum of 24 newly diagnosed, untreated GCA/PMR patients, 14 corticosteroid (CS)-treated GCA/PMR patients in remission and 13 ...

PURPOSE To investigate the effects of T-cell-derived cytokines on gene and protein expression of chemokines in a human RPE cell line (ARPE-19). METHODS We used an in vitro coculture system in which the RPE and CD3/CD28-activated T-cells were separated by a membrane. RPE cell expression of chemokine genes was quantified using three different types of microarrays. Protein expression was determi...

OBJECTIVE To assess whether serum levels of CC and CXC chemokines correlate with disease activity in patients with rheumatoid arthritis (RA), and to determine whether these effects predict clinical response. METHODS Serum levels of the chemokines CC (CCL2, CCL5) and CXC (CXCL8, CXCL9, CXCL10) were quantified at baseline and after 12 weeks of treatment with disease-modifying antirheumatic drug...

Adult neural precursor cells (NPCs) respond to injury or disease of the CNS by migrating to the site of damage or differentiating locally to replace lost cells. Factors that mediate this injury induced NPC response include chemokines and pro-inflammatory cytokines, such as tumor necrosis factor-α (TNFα) and interferon-γ (IFNγ), which we have shown previously promotes neuronal differentiation. R...

According to the current paradigm, allergic airway inflammation is mediated by Th2 cytokines and pro-inflammatory chemokines. Since allergic inflammation is self-limited, we hypothesized that allergen challenge simultaneously induces anti-inflammatory genes to counter-balance the effects of Th2 cytokines and chemokines. To identify these putative anti-inflammatory genes, we compared the gene ex...

Abstract Background Immune checkpoint blockade (ICB)-based cancer immunotherapy presents promising efficacy in treatment. However, only a small portion of patients show responsiveness to the treatment, which is partially caused by limited tumor infiltration T cells. Chemokines CXCL9, CXCL10 and CXCL11 bind their receptor CXCR3 regulate cell invasion. Methods We delivered plasmids encoding cells...
