Molecular Signatures of G-Protein-Coupled Receptors A
REVIEW doi:10.1038/nature11896 Molecular signatures of G-protein-coupled receptors A. J. Venkatakrishnan1, Xavier Deupi2, Guillaume Lebon1,3,4,5, Christopher G. Tate1, Gebhard F. Schertler2,6 & M. 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. A holistic understanding that integrates molecular and systems biology of GPCRs holds promise for new therapeutics and personalized medicine. ignal transduction is a fundamental biological process that is comprehensively, and in the process expand the current frontiers of required to maintain cellular homeostasis and to ensure coordi- GPCR biology.

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 -
Original Article Expression of Chemokine Receptor CXCR5 in Gastric Cancer and Its Clinical Significance

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. -
Defining Natural Antibodies
PERSPECTIVE published: 26 July 2017 doi: 10.3389/fimmu.2017.00872 Defining Natural Antibodies Nichol E. Holodick1*, Nely Rodríguez-Zhurbenko2 and Ana María Hernández2* 1 Department of Biomedical Sciences, Center for Immunobiology, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo, MI, United States, 2 Natural Antibodies Group, Tumor Immunology Division, Center of Molecular Immunology, Havana, Cuba The traditional definition of natural antibodies (NAbs) states that these antibodies are present prior to the body encountering cognate antigen, providing a first line of defense against infection thereby, allowing time for a specific antibody response to be mounted. The literature has a seemingly common definition of NAbs; however, as our knowledge of antibodies and B cells is refined, re-evaluation of the common definition of NAbs may be required. Defining NAbs becomes important as the function of NAb production is used to define B cell subsets (1) and as these important molecules are shown to play numerous roles in the immune system (Figure 1). Herein, we aim to briefly summarize our current knowledge of NAbs in the context of initiating a discussion within the field of how such an important and multifaceted group of molecules should be defined. Edited by: Keywords: natural antibody, antibodies, natural antibody repertoire, B-1 cells, B cell subsets, B cells Harry W. Schroeder, University of Alabama at Birmingham, United States NATURAL ANTIBODY (NAb) PRODUCING CELLS Reviewed by: Andre M. Vale, Both murine and human NAbs have been discussed in detail since the late 1960s (2, 3); however, Federal University of Rio cells producing NAbs were not identified until 1983 in the murine system (4, 5). -

CXCR6 Within T-Helper (Th) and T-Cytotoxic
European Journal of Endocrinology (2005) 152 635–643 ISSN 0804-4643 EXPERIMENTAL STUDY CXCR6 within T-helper (Th) and T-cytotoxic (Tc) type 1 lymphocytes in Graves’ disease (GD) G Aust, M Kamprad1, P Lamesch2 and E Schmu¨cking Institute of Anatomy, 1Department of Clinical Immunology and Transfusion Medicine and 2Department of Surgery, University of Leipzig, Phillipp-Rosenthal-Str. 55, Leipzig, 04103, Germany (Correspondence should be addressed to G Aust; Email: [email protected]) Abstract Objective: In Graves’ disease (GD), stimulating anti-TSH receptor antibodies are responsible for hyperthyroidism. T-helper 2 (Th2) cells were expected to be involved in the underlying immune mech- anism, although this is still controversial. The aim of this study was to examine the expression of CXCR6, a chemokine receptor that marks functionally specialized T-cells within the Th1 and T-cyto- toxic 1 (Tc1) cell pool, to gain new insights into the running immune processes. Methods: CXCR6 expression was examined on peripheral blood lymphocytes (PBLs) and thyroid- derived lymphocytes (TLs) of GD patients in flow cytometry. CXCR6 cDNA was quantified in thyroid tissues affected by GD (n ¼ 16), Hashimoto’s thyroiditis (HT; n ¼ 2) and thyroid autonomy (TA; n ¼ 11) using real-time reverse transcriptase PCR. Results: The percentages of peripheral CXCR6þ PBLs did not differ between GD and normal subjects. CXCR6 was expressed by small subsets of circulating T-cells and natural killer (NK) cells. CXCR6þ cells were enriched in thyroid-derived T-cells compared with peripheral CD4þ and CD8þ T-cells in GD. The increase was evident within the Th1 (CD4þ interferon-gþ (IFN-gþ)) and Tc1 (CD8þIFN- gþ) subpopulation and CD8þ granzyme Aþ T-cells (cytotoxic effector type). -
