sarcoidosis is a systemic granulomatous disorder of unidentified etiology, with a heterogeneous clinical presentation. it is characterized by a reduced delayed-type hypersensitivity to tuberculin and common antigens. the balance between th1, th17 and regulatory t(treg) cells controls t-cell proliferation and activation.the th17/treg ratio in the peripheral blood and bronchoalveolar lavage fluid...
Abstract Objective: Interferon-γ (IFN-γ) is a key cytokine regulating the development of atherosclerosis, but little known regarding phenotype and regulation T cells producing IFN-γ in plaques. Methods: To identify characterize IFN-γ-producing we utilized IFN-γ-YFP Nur77-GFP reporter mice crossed onto an atherosclerotic background (Apoe−/−IFN-γ YFP/YFP; Apoe−/−Nur77GFP/wt), adoptive transfer tr...
Objective(s): Multiple sclerosis (MS) is considered as a chronic type of an inflammatory disease characterized by loss of myelin of CNS.Recent evidence indicates that Interleukin 17 (IL-17)-producing T helper cells (Th17 cells) population are increased and regulatory T cells (Treg cells) are decreased in MS. Despite extensive research in understanding the mechanism of Th17 and Treg differentiat...
The first gene profiling study of cancer-specific CD8+ T-cells demonstrates that lymphocyte dysfunction in cancer tissue is due to multiple molecular alterations,(1) similar as in "exhausted" T-cells in chronic infection.(2) The data suggest novel drug targets, and show that T-cell exhaustion is reversible and limited to anatomical sites of disease.
Chronic infections with human viruses, such as HIV and HCV, or mouse viruses, such as LCMV or Friend Virus (FV), result in functional exhaustion of CD8(+) T cells. Two main mechanisms have been described that mediate this exhaustion: expression of inhibitory receptors on CD8(+) T cells and expansion of regulatory T cells (Tregs) that suppress CD8(+) T cell activity. Several studies show that bl...
