    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.

    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.

    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.

    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.

    Immunosuppressive activity of regulatory T and B cells is critical to limit autoimmunity, excessive inflammation, and pathological immune response to conventional antigens or allergens. Both types of regulatory cells are intensively investigated, however, their development and mechanisms of action are still not completely understood. Both T and B regulatory cells represent highly differentiated populations in terms of phenotypes and origin, however, they use similar mechanisms of action. Read More

    Regulation of immune response was found to play an important role in the course of many diseases such as autoimmune diseases, allergy, malignancy, organ transplantation. The studies on immune regulation focus on the role of regulatory cells (Tregs, Bregs, regulatory myeloid cells) in these disorders. The number and function of Tregs may serve as a marker of disease activity. Read More

    CD1: A Singed Cat of the Three Antigen Presentation Systems.

    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

    Human Gyrovirus-Apoptin Interferes with the Cell Cycle and Induces G2/M Arrest Prior to Apoptosis.

    The human gyrovirus-Apoptin (HGyv-Apoptin) is a protein that gained attention because it is selectively cytotoxic toward cancer cells. In this study, we have investigated the effect of HGyv-Apoptin on cell cycle progression of cancer cells. We also compared HGyv-Apoptin's action to its homologue chicken anemia virus Apoptin (CAV-Apoptin). Read More

    Evaluation of Endothelial Function by Flow-Mediated Dilation: a Comprehensive Review in Rheumatic Disease.
    Arch Immunol Ther Exp (Warsz) 2017 Dec 30;65(6):463-475. 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).

    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
