    The PD-1/PD-L1 Inhibitory Pathway is Altered in Primary Glomerulonephritides.
    Arch Immunol Ther Exp (Warsz) 2017 Aug 2. Epub 2017 Aug 2.
    Department of Nephrology, Cardinal Stefan Wyszynski Provincial Hospital in Lublin, Lublin, Poland.
    The pathogenesis of primary proliferative and non-proliferative glomerulonephritides (PGN and NPGN) is still not fully understood, however, current evidence suggests that most cases of PGN and NPGN are the results of immunologic response to different etiologic agents that activates various biological processes leading to glomerular inflammation and injury. Programmed cell death protein 1 (PD-1) is the major inhibitory receptor regulating T cell exhaustion. The aim of this study was to evaluate the frequencies of PD-1-positive and PD-ligand 1 (PD-L1)-positive T and B lymphocytes in patients with NPGN and PGN in relation to clinical parameters for the first time.

    Laboratory of Experimental Medicine, Centre of New Technologies, University of Warsaw, Banacha 2c, 02-097, Warsaw, Poland.
    Stimulator of interferon genes (STING) is an adaptor protein that plays an important role in the activation of type I interferons in response to cytosolic nucleic acid ligands. Recent evidence indicates involvement of the STING pathway in the induction of antitumor immune response. Therefore, STING agonists are now being extensively developed as a new class of cancer therapeutics. Read More

    Role of TGF-β in Self-Peptide Regulation of Autoimmunity.
    Arch Immunol Ther Exp (Warsz) 2017 Jul 21. Epub 2017 Jul 21.
    Department of Microbiology & Immunology, Centre for Human Immunology, University of Western Ontario, London, ON, N6A 5C1, Canada.
    Transforming growth factor (TGF)-β has been implicated in regulation of the immune system, including autoimmunity. We have found that TGF-β is readily produced by T cells following immunization with self-peptide epitopes that downregulate autoimmune responses in type 1 diabetes (T1D) prone nonobese diabetic (NOD) mice. These include multiple peptide epitopes derived from the islet β-cell antigens GAD65 (GAD65 p202-221, GAD65 p217-236), GAD67 (GAD67 p210-229, GAD67 p225-244), IGRP (IGRP p123-145, IGRP p195-214) and insulin B-chain (Ins.

    Department of Virology and Immunology, Institute of Microbiology and Biotechnology, Maria Curie-Skłodowska University, Akademicka 19, 20-033, Lublin, Poland.
    It is well known that the microenvironment of solid tumors is rich in inflammatory cells that influence tumor growth and development. Macrophages, called tumor-associated macrophages (TAMs), are the most abundant immune cell population present in tumor tissue. Several studies have demonstrated that the density of TAMs is associated with a poor prognosis and positively correlates with tumor growth. Read More

    Anti-GITR Antibody Treatment Increases TCR Repertoire Diversity of Regulatory but not Effector T Cells Engaged in the Immune Response Against B16 Melanoma.
    Arch Immunol Ther Exp (Warsz) 2017 Jun 21. Epub 2017 Jun 21.
    Department of Tumor Immunology, Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, R. Weigla 12, 53-114, Wrocław, Poland.
    Crosslinking of glucocorticoid-induced TNF family-related receptor (GITR) with agonist antibodies restores cancer immunity by enhancing effector T cell (Teff) responses while interfering with intra-tumor regulatory T cell (Treg) stability and/or accumulation. However, how anti-GITR antibody infusion changes T cell receptor (TCR) repertoire of Teffs and Tregs engaged in anti-tumor immune response is unclear. Here, we used a transgenic mouse model (TCRmini) where T cells express naturally generated but limited TCR repertoire to trace the fate of individual T cells recognizing B16 melanoma in tumor-bearing mice, treated or non-treated with an anti-GITR monoclonal antibody DTA-1.

    The Immune Response in Periodontal Tissues.
    Arch Immunol Ther Exp (Warsz) 2017 Jun 6. Epub 2017 Jun 6.
    Department of Periodontology and Oral Diseases, Medical University of Warsaw, Miodowa 18, Warsaw, 00-246, Poland.
    The uniqueness of periodontal diseases is caused by several factors. This group of diseases is caused by numerous bacterial species formed in the dental biofilm, and one cannot distinguish the specific pathogen that is responsible for the disease initiation or progress (though Gram-negative anaerobic rods are associated with the advanced form of the disease). The disease is both infectious and inflammatory in its nature, and in the state of health there is always a subclinical level of inflammatory response, caused by the so-called harmless bacteria.

    The Potential Role of Krüppel-Like Zinc-Finger Protein Glis3 in Genetic Diseases and Cancers.
    Arch Immunol Ther Exp (Warsz) 2017 May 18. Epub 2017 May 18.
    Department of Biotechnology, Kaohsiung Medical University, Kaohsiung, 807, Taiwan.
    Gli-similar 3 (Glis3) belongs to a Glis subfamily of Krüppel-like zinc-finger transcription factors characterized to regulate a set of downstream targets essential for cellular functions, including pancreatic development, β-cell maturation and maintenance, and insulin production. Examination of the DNA-binding domain of Glis3 reveals that this domain contains a repeated cysteine 2/histidine 2 (Cys2/His2) zinc-finger motif in the central region where the recognized DNA sequence binds. The loss of the production of pancreatic hormones, such as insulin 1 and 2, is linked to the down-regulation of β cells-related genes and promotes the apoptotic death of β cells found in mutant Glis3.

    CD1: A Singed Cat of the Three Antigen Presentation Systems.
    Arch Immunol Ther Exp (Warsz) 2017 Jun 6;65(3):201-214. Epub 2017 Apr 6.
    Laboratory of Glycoconjugate Immunochemistry, Hirszfeld Institute of Immunology and Experimental Therapy, Polish Academy of Sciences, Wrocław, Poland.
    Contrary to general view that the MHC Class I and II are the kapellmeisters of recognition and response to antigens, there is another big player in that part of immunity, represented by CD1 glycoproteins. In contrast to MHC Class I or II, which present peptides, CD1 molecules present lipids. Humans express five CD1 proteins (CD1a-e), four of which (CD1a-d) are trafficked to the cell surface, where they may display lipid antigens to T-cell receptors. Read More

    Evaluation of Endothelial Function by Flow-Mediated Dilation: a Comprehensive Review in Rheumatic Disease.
    Arch Immunol Ther Exp (Warsz) 2017 Mar 30. Epub 2017 Mar 30.
    University of Milan, Milan, Italy.
    Flow-mediated dilation (FMD) represents a non-invasive marker of endothelial function to evaluate vascular homeostasis, which reflects the effects of several mechanisms, including vessel tone regulation, cell proliferation, and inflammatory responses. Beyond classical atherosclerotic risk factors such as arterial hypertension, diabetes mellitus, smoking, obesity, and dyslipidemia, chronic inflammation contributes to the endothelial dysfunction causing plaque formation and there is growing evidence of a significantly higher cardiovascular morbidity associated with autoimmune diseases. The endothelium reacts to several endogenous and exogenous stimuli, through surface receptors and intracellular signalling, and releases numerous vasoactive substances, including endothelins, prostacyclins, and nitric oxide (NO).

    The transplantation of mesenchymal stem cells derived from unconventional sources: an innovative approach to multiple sclerosis therapy.
    Arch Immunol Ther Exp (Warsz) 2017 Mar 25. Epub 2017 Mar 25.
    Department of Experimental Neurology Laboratory, IRCCS Centro Neurolesi "Bonino-Pulejo", Via Provinciale Palermo, Contrada Casazza, 98124, Messina, Italy.
    In recent years, in the effort to find a potential innovative therapy for multiple sclerosis (MS), researchers focused on transplantation of mesenchymal stem cells (MSCs) due to their well-recognized ability to suppress inflammatory/autoimmune responses and exert neuroregenerative properties. MSCs are a heterogeneous subset of pluripotent non-hematopoietic stromal cells that can be isolated from many different adult tissues, characterized by the capability to differentiate into various cell lineages, and to translocate into damaged areas, providing immunomodulatory effects. To date, several encouraging results were obtained mainly from the use of MSCs derived from the bone marrow (BM-MSCs) in experimental models of MS as well as in clinical trials. Read More

    Perillyl alcohol, a pleiotropic natural compound suitable for brain tumor therapy, targets free radicals.
    Arch Immunol Ther Exp (Warsz) 2017 Aug 17;65(4):285-297. Epub 2017 Mar 17.
    Department of Cellular and Molecular Biology, Institute of Biology, Fluminense Federal University, Niteroi, RJ, 24020-141, Brazil.
    Monoterpenes such as limonene and perillyl alcohol (POH) are promising natural compounds with pro-oxidant properties partly due to endoplasmic reticulum (ER) stress-induced cytotoxicity, and antioxidant activity owing to their activity as free radical scavengers, inhibition of coenzyme Q synthesis, activation of antioxidant-responsive elements (inducing detoxification enzymes) and induction of apoptosis. Activation of ER-stress responses generates reactive oxygen species (ROS), which are highly reactive free radicals mainly produced during mitochondrial electron transfer for adenosine triphosphate (ATP) synthesis. When cells are subjected to oxidative stress conditions, there is an accumulation of ROS that can lead to irreversible cell injury caused primarily by lipid peroxidation, protein aggregation and/or DNA damage.

    Allogeneic hematopoietic stem cell transplantation (aHSCT) is used as a curative treatment in severe hematological and immunological disorders. Despite clear improvement of the aHSCT outcome, substantial proportion of patients still suffers from severe complications, including graft-versus-host disease (GvHD). The aim of this study was, therefore, to identify inflammation-associated molecules deregulated in the early serum samples of the patients after aHSCT and nominate markers associated with particular aHSCT parameters/complications.

    Psoriatic arthritis (PsA) is a chronic inflammatory disorder that belongs to the group of spondyloarthritis (SpA). It was found that single nucleotide polymorphisms (SNPs) of endoplasmic reticulum aminopeptidase (ERAP1 and ERAP2) genes influence the risk of ankylosing spondylitis, the most common form of SpA and the risk of psoriasis. Our purpose was to investigate the possible association of ERAP1 and ERAP2 gene SNPs with psoriatic arthritis susceptibility in Romanian population. Read More

    Department of Rheumatology and Internal Medicine, Wroclaw Medical University, Borowska 213, 50-556, Wroclaw, Poland.
    MicroRNA-146a (miR-146a) has been shown to play an important role in the regulation of inflammatory innate immune responses, and found to be differentially expressed in rheumatoid arthritis (RA). Through NF-κB pathway, this molecule is able to stimulate the release of pro-inflammatory cytokines such as TNF-α, IL-1β, and IL-17. It has been also suggested that single-nucleotide polymorphisms (SNPs) in miRNA sequences may alter miRNA expression and that miR-146a rs2910164 SNP may contribute to RA development. Read More

    An effective cytotoxic immune response to neoplastic cells requires efficient presentation of antigenic peptides to T lymphocytes by HLA class I (HLA-I) molecules. The HLA-I-bound peptide repertoire depends on antigen-processing machinery molecules. Aminopeptidase residing in endoplasmic reticulum 1 (ERAP1) trims peptides to the optimal length for HLA-I binding. Read More

    The B-cell activating factor (BAFF) cytokine has important functions for the survival and maturation of B lymphocytes, which implies that this cytokine might play a role in the development of antibody-mediated rejection (AMR) after kidney transplantation. In our study, we compared the concentrations of the soluble BAFF cytokine in kidney graft recipients with AMR and patients without rejection with the goal of testing the hypothesis whether BAFF level measurement might be useful as a diagnostic marker of AMR. The study included a cohort of 19 high-risk patients with diagnosed AMR and 17 control patients free of rejection. Read More
