The Journal of Immunology Dendritic Cells Support Sequential Reprogramming of Chemoattractant Receptor Profiles During Naive to Effector T Cell Differentiation1 Chang H. Kim,2* Kinya Nagata,† and Eugene C. Butcher‡ T cells undergo chemokine receptor switches during activation and differentiation in secondary lymphoid tissues. Here we present evidence that dendritic cells can induce changes in T cell expression of chemokine receptors in two continuous steps. In the first switch over a 4–5 day period, dendritic cells up-regulate T cell expression of CXCR3 and CXCR5. Additional stimulation leads to the second switch: down-regulation of lymphoid tissue homing related CCR7 and CXCR5, and up-regulation of Th1/2 effector tissue-targeting chemoattractant receptors such as CCR4, CCR5, CXCR6, and CRTH2. We show that IL-4 and IL-12 can determine the fate of the secondary chemokine receptor switch. IL-4 enhances the generation of CCR4؉ and CRTH2؉ T cells, and Downloaded from .suppresses the generation of CXCR3؉ T cells and CCR7؊ T cells, while IL-12 suppresses the level of CCR4 in responding T cells Furthermore, IL-4 has positive effects on generation of CXCR5؉ and CCR7؉ T cells during the second switch. Our study suggests that the sequential switches in chemokine receptor expression occur during naive T cell interaction with dendritic cells. The first switch of T cell chemokine receptor expression is consistent with the fact that activated T cells migrate within lymphoid tissues for interaction with B and dendritic cells, while the second switch predicts the trafficking behavior of effector T cells away from lymphoid tissues to effector tissue sites.

Donnelly, Airway Disease, National Heart and Lung Institute, Dovehouse Street, London, SW3 6LY, UK. E-mail: [email protected] ABSTRACT Chronic obstructive pulmonary disease (COPD) patients exhibit chronic inflammation, both in the lung parenchyma and the airways, which is characterised by an increased infiltration of macrophages and T-lymphocytes, particularly CD8+ cells. Both cell types can express chemokine (C-X-C motif) receptor (CXCR)3 and C-C chemokine receptor 5 and the relevant chemokines for these receptors are elevated in COPD. The aim of this study was to compare chemotactic responses of lymphocytes and monocytes of nonsmokers, smokers and COPD patients towards CXCR3 ligands and chemokine (C-C motif) ligand (CCL)5. Migration of peripheral blood mononuclear cells, monocytes and lymphocytes from nonsmokers, smokers and COPD patients toward CXCR3 chemokines and CCL5 was analysed using chemotaxis assays. There was increased migration of peripheral blood mononuclear cells from COPD patients towards all chemokines studied when compared with nonsmokers and smokers. Both lymphocytes and monocytes contributed to this enhanced response, which was not explained by increased receptor expression.

  • Cytokines (CCL25)
    Mouse Recombinant TECK Cytokines (CCL25) Thymus-expressed chemokine Catalog # 78180 5 μg 78180.1 25 μg Product Description Thymus-expressed chemokine (TECK), or CCL25, is a member of the CC family of chemokines that regulates the movement of lymphocytes in the thymus and in the small intestine. TECK induces chemoattraction by binding the chemokine receptor CCR9, which is expressed on immature pre-T cells and thymocytes (Youn et al.; Uehara et al.). In the thymus, TECK is produced by stromal cells, whereas in the small intestine TECK is primarily produced by epithelial cells (Vicari et al.; Bowman et al.; Kunkel et al.). CCR9 is a G protein-coupled receptor and is expressed on most thymocytes, but not on natural killer cells, monocytes, eosinophils, basophils, and neutrophils (Wu et al). In Jurkat cells, binding of TECK to CCL9 has been shown to increase levels of intracellular calcium (Cheng-Rong et al). TECK/CCR9 signaling has also been linked to many cancers, as these molecules have been shown to mediate anti-apoptotic processes by activating the PI3K/AKT signaling pathway, weakening the effect of cytotoxic T cells by regulating STAT signaling. Additionally, TECK induces metastasis by increasing the expression of MMP2 and MMP9 (Tu et al.).

Madan Babu1 G-protein-coupled receptors (GPCRs) are physiologically important membrane proteins that sense signalling molecules such as hormones and neurotransmitters, and are the targets of several prescribed drugs. Recent exciting developments are providing unprecedented insights into the structure and function of several medically important GPCRs. Here, through a systematic analysis of high-resolution GPCR structures, we uncover a conserved network of non-covalent contacts that defines the GPCR fold. Furthermore, our comparative analysis reveals characteristic features of ligand binding and conformational changes during receptor activation.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

  • Neutrophil Chemoattractant Receptors in Health and Disease: Double-Edged Swords
    Cellular & Molecular Immunology www.nature.com/cmi REVIEW ARTICLE Neutrophil chemoattractant receptors in health and disease: double-edged swords Mieke Metzemaekers1, Mieke Gouwy1 and Paul Proost 1 Neutrophils are frontline cells of the innate immune system. These effector leukocytes are equipped with intriguing antimicrobial machinery and consequently display high cytotoxic potential. Accurate neutrophil recruitment is essential to combat microbes and to restore homeostasis, for inflammation modulation and resolution, wound healing and tissue repair. After fulfilling the appropriate effector functions, however, dampening neutrophil activation and infiltration is crucial to prevent damage to the host. In humans, chemoattractant molecules can be categorized into four biochemical families, i.e., chemotactic lipids, formyl peptides, complement anaphylatoxins and chemokines. They are critically involved in the tight regulation of neutrophil bone marrow storage and egress and in spatial and temporal neutrophil trafficking between organs. Chemoattractants function by activating dedicated heptahelical G protein-coupled receptors (GPCRs). In addition, emerging evidence suggests an important role for atypical chemoattractant receptors (ACKRs) that do not couple to G proteins in fine-tuning neutrophil migratory and functional responses. The expression levels of chemoattractant receptors are dependent on the level of neutrophil maturation and state of activation, with a pivotal modulatory role for the (inflammatory) environment. Here, we provide an overview

Received January 8, 2016; Accepted March 22, 2016; Epub July 1, 2016; Published July 15, 2016 Abstract: The increased expression of chemokine receptor CXCR5 in cancers has been demonstrated. In order to characterize the expression pattern of CXCR5 in cell lines and tissues of gastric cancer and to assess clinical implications, the expression of CXCR5 mRNA in gastric cancer tissues and adjacent tissues was evaluated by real- time RT-PCR. Meanwhile, the expression of CXCR5 in cell lines of human gastric cancer was also analyzed by flow cytometry. Tissue microarray and immunohistochemistry were used to detect the protein expression of CXCR5 in human gastric cancer tissues and adjacent normal tissues. Flow cytometry results revealed the positive expression of CXCR5 in human gastric cancer cell lines such as BGC-823, SGC-7901 and HGC-27 cells. The immunohistochem- istry results showed higher expression of CXCR5 in 52.87% of gastric cancer tissues. The expression of CXCR5 in patients with tumor size less than 2.8 cm subgroup was significantly lower than that in patients with tumor size larger than 2.8 cm subgroup (P = 0.0456). There was no significant correlation between the expression of CXCR5 and other clinical parameters in gastric cancer.
