Products for Chemokine Research RnDSy-lu-2945 Products for Chemokine Research The Chemokine Superfamily Chemokines are small cell surface-localized or secreted chemotactic cytokines that bind to and activate specific G protein-coupled chemokine receptors. Most chemokines have at least four conserved N-terminal cysteine residues that form two intramolecular disulfide bonds. Four chemokine subfamilies (CXC, CC, C and CX3C) have been defined based upon the placement of the first two cysteine residues. The CXC chemokine subfamily is characterized by two cysteine residues separated by one amino acid. Within this subfamily, two CXC classes are further defined by the presence or absence of an ELR motif sequence. ELR– CXC chemokines act as chemoattractants for lymphocytes, while ELR+ CXC chemokines are chemoattractants for neutrophils. Additionally, CXC chemokines can mediate angiogenesis.1 The CC chemokine subfamily is defined by two adjacent cysteine CCR1 H: CCL3-5, 7, 8, 13-16, 23, CCL3L1, CCL3L3, CCL4L1, CCL4L2 M: CCL3-7, 9/10 residues. CC chemokines induce inflammatory H: XCL1, 2 XCR1 responses via regulation of monocyte, M: XCL1 macrophage, mast cell, and T cell migration.2 H: CCL2, 7, 8, 13, 16 CCR2 (A or B) M: CCL2, 7, 12 C chemokines are characterized by a single H: CCL26 CX3CR1 cysteine residue and are constitutively expressed H: CX3CL1 in the thymus where they regulate T cell H: CCL5, 7, 8, 11, 13, 14, 15, 24, 26, 28, CCL3L1, CCL3L3 M: CX3CL1 CCR3 M: CCL5, 7, 9/10, 11, 24 differentiation.3 The CX3C chemokine subfamily is defined by two cysteine residues separated by H: CXCL6-8 CXCR1 three amino acids. Cell surface-localized CX3CL1/ H: CCL2, 3, 5, 17, 22 M: CXCL7, LIX CCR4 Fractalkine mediates leukocyte adhesion while M: CCL2, 3, 5, 17, 22 soluble CX3CL1/Fractalkine is chemotactic for H: CXCL1-3, 5-8 leukocytes.4 CX3CL1/Fractalkine is also a critical H: CCL3-5, 8, 11, 13, 14, 16, CCL3L1, M: CXCL1-3, 7, LIX CXCR2 CCR5 CCL3L3, CCL4L1, CCL4L2 regulator of microglia-neuron communication M: CCL3-5 during neural development.5 H: CXCL4, 9-11, 13, CXCL4L1 While chemokine receptors generally bind only CCR6 H: CCL20 M: CXCL4, 9-11 CXCR3 M: CCL20 one subfamily of chemokines, within those subfamilies, most chemokines display promiscuous receptor binding patterns. The CCR7 H: CCL19, 21 M: CCL19, 21 H: CXCL4, 9-11, CXCL4L1 CXCR3B redundancy of chemokine ligand-receptor binding may ensure robust signaling. In addition, promiscuous binding and non-signaling CCR8 H: CCL1, 4, 16, 17 M: CCL1, 8 H: CXCL12 CXCR4 chemokine receptors offer mechanisms by which M: CXCL12 chemokine signaling can be regulated by either subtle differences in receptor signaling or H: CCL25 CCR9 M: CCL25 differences in ligand-receptor expression H: CXCL13 M: CXCL13 CXCR5 patterns.6 Select chemokine ligands and receptors are implicated in HIV infection and H: CCL27, 28 CCR10 M: CCL27, 28 persistence, while aberrant chemokine H: CXCL16 expression and signaling is associated with M: CXCL16 CXCR6 pathological conditions including inflammatory CCR11 H: CCL2, 8, 13, 19, 21, 25 diseases and cancer.7-9 M: CCL19, 21, 25 References H: CXCL11, 12 CXCR7 1.

  • CCL19-Igg Prevents Allograft Rejection by Impairment of Immune Cell Trafficking
    CCL19-IgG Prevents Allograft Rejection by Impairment of Immune Cell Trafficking Ekkehard Ziegler,* Faikah Gueler,† Song Rong,† Michael Mengel,‡ Oliver Witzke,§ Andreas Kribben,§ Hermann Haller,† Ulrich Kunzendorf,* and Stefan Krautwald* *Department of Nephrology and Hypertension, University of Kiel, Kiel, †Department of Internal Medicine and ‡Institute for Pathology, Hannover Medical School, Hannover, and §Department of Nephrology, School of Medicine, University of Duisburg-Essen, Essen, Germany An adaptive immune response is initiated in the T cell area of secondary lymphoid organs, where antigen-presenting dendritic cells may induce proliferation and differentiation in co-localized T cells after T cell receptor engagement. The chemokines CCL19 and CCL21 and their receptor CCR7 are essential in establishing dendritic cell and T cell recruitment and co- localization within this unique microenvironment. It is shown that systemic application of a fusion protein that consists of CCL19 fused to the Fc part of human IgG1 induces effects similar to the phenotype of CCR7؊/؊ animals, like disturbed accumulation of T cells and dendritic cells in secondary lymphoid organs. CCL19-IgG further inhibited their co-localization, which resulted in a marked inhibition of antigen-specific T cell proliferation. The immunosuppressive potency of CCL19-IgG was tested in vivo using murine models for TH1-mediated immune responses (delayed-type hypersensitivity) and for transplantation of different solid organs. In allogeneic kidney transplantation as well as heterotopic allogeneic heart transplantation in different strain combinations, allograft rejection was reduced and organ survival was significantly prolonged by treatment with CCL19-IgG compared with controls. This shows that in contrast to only limited prolongation of graft survival in CCR7 knockout models, the therapeutic application of a CCR7 ligand in a wild-type environment provides a benefit in terms of immunosuppression.

  • Complementary DNA Microarray Analysis of Chemokines and Their Receptors in Allergic Rhinitis RX Zhang,1 SQ Yu,2 JZ Jiang,3 GJ Liu3
    RX Zhang, et al ORIGINAL ARTICLE Complementary DNA Microarray Analysis of Chemokines and Their Receptors in Allergic Rhinitis RX Zhang,1 SQ Yu,2 JZ Jiang,3 GJ Liu3 1 Department of Otolaryngology, Huadong Hospital, Fudan University, Shanghai, China 2 Department of Otolaryngology , Jinan General Hospital of PLA, Shandong, China 3 Department of Otolaryngology, Changhai Hospital, Second Military Medical University, Shanghai, China ■ Abstract Objective: To analyze the roles of chemokines and their receptors in the pathogenesis of allergic rhinitis by observing the complementary DNA (cDNA) expression of the chemokines and their receptors in the nasal mucosa of patients with and without allergic rhinitis, using gene chips. Methods: The total RNAs were isolated from the nasal mucosa of 20 allergic rhinitis patients and purifi ed to messenger RNAs, and then reversely transcribed to cDNAs and incorporated with samples of fl uorescence-labeled with Cy5-dUPT (rhinitis patient samples) or Cy3- dUTP (control samples of nonallergic nasal mucosa). Thirty-nine cDNAs of chemokines and their receptors were latticed into expression profi le chips, which were hybridized with probes and then scanned with the computer to study gene expression according to the different fl uorescence intensities. Results: The cDNAs of the following chemokines were upregulated: CCL1, CCL2, CCL5, CCL7, CCL8, CCL11, CCL13, CCL14, CCL17, CCL18, CCL19, CCL24, and CX3CL1 in most of the allergic rhinitis sample chips. CCR2, CCR3, CCR4, CCR5, CCR8 and CX3CR1 were the highly expressed receptor genes. Low expression of CXCL4 was found in these tissues. Conclusion: The T helper cell (TH) immune system is not well regulated in allergic rhinitis.

  • Ccl9 Induced by Tgf-Β Signaling in Myeloid Cells Enhances Tumor Cell Survival in the Premetastatic Lung
    CCL9 INDUCED BY TGF-β SIGNALING IN MYELOID CELLS ENHANCES TUMOR CELL SURVIVAL IN THE PREMETASTATIC LUNG by Hangyi Yan A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland March, 2015 ABSTRACT The majority of cancer patients die from metastasis. To achieve metastasis, tumor cells must first survive and then proliferate to form colonies. Compelling data have shown the indispensable participation of host microenvironment for metastasis. Bone marrow derived myeloid cells sculpt a tumor-promoting microenvironment in the premetastatic organs prior to tumor cell arrival. However, the molecular mechanisms for this “seed and soil” hypothesis are unclear. Here we report that CCL9 was significantly produced and secreted by Gr-1+CD11b+ cells when co-cultured with tumor cells, and in the premetastatic lung. CCL9 knockdown (KD) in myeloid cells decreased metastasis, and this process signaled through its sole receptor CCR1. Overexpression of CCR1 lost the metastasis-promoting function in the context of CCL9 KD. CCL9 enhanced tumor cell survival in the premetastatic organs. The underlying molecular mechanisms included activation of cell survival factors phosphorylated AKT and BCL-2, as well as inhibition of Poly (ADP-ribose) polymerase (PARP)-dependent apoptosis pathway. Additionally, CCL9/CCR1 had autocrine effects, which enhanced CCL9 secretion and the survival of Gr-1+CD11b+ cells. We found that CCL9 was a key effector of myeloid transforming growth factor β (TGF-β) pathway that promotes metastasis. Decreased metastasis in mice with myeloid specific TGF-β receptor II deletion (Tgfbr2MyeKO) correlated with lower CCL9 expression in TGF-β deficient myeloid cells.

Previ- INTRODUCTION ously, we showed that ovalbumin (OVA)-triggered neutrophil migration in immunized mice depends on the sequential release of tumor necrosis factor Neutrophil migration is a complex process, which results ␣ ␣ mainly from the release of neutrophil chemotactic factors by (TNF- ) and leukotriene B4 (LTB4). Herein, we show increased mRNA expression for MIP- resident cells, inducing rolling and adhesion of neutrophils on 1␣[CCL3], MIP-1␤[CCL4], RANTES[CCL5], and endothelial cells, followed by their transmigration to the ex- travascular space [1, 2]. Apart from its importance in host CCR1 in peritoneal cells harvested from OVA-chal- defense, the migration of neutrophils to the inflammatory site lenged, immunized mice, as well as MIP-1␣[CCL3] is, at least in part, responsible for tissue damage observed in and RANTES[CCL5] but not MIP-1␤[CCL4] proteins several inflammatory diseases such as rheumatoid arthritis, in the peritoneal exudates.

The tumor microenvironment usually prevents effective lymphocyte activation and infiltration, and suppresses infiltrating effector cells, leading to a failure of the host toreject the tumor. CC chemokines play a significant role in inflammation and infection. Methods: In our study, we analyzed the expression and survival data of CC chemokines in patients with BC using several bioinformatics analyses tools. Results: The mRNA expression of CCL2/3/4/5/7/8/11/17/19/20/22 was remark- ably increased while CCL14/21/23/28 was significantly down-regulated in BC tis- sues compared with normal tissues. Methylation could down-regulate expression of CCL2/5/15/17/19/20/22/23/24/25/26/27 in BC. Low expression of CCL3/4/23 was found to be associated with drug resistance in BC.
