Immune tolerance is executed partly by Foxp3(+)regulatory T (Treg) cells, which suppress autoreactive T cells. In autoimmune type 1 diabetes (T1D) impaired tolerance promotes destruction of insulin-producing β-cells. The development of autoantigen-specific vaccination strategies for Foxp3(+)Treg-induction and prevention of islet autoimmunity in patients is still in its infancy. Here, using huma...
Innate immunity and immunological biomarkers are believed to be interrelated with sex hormones and other neuroendocrine factors. Sexual dimorphism mechanisms may be operating in certain rheumatic and inflammatory diseases which occur more frequently in women than men, as rheumatoid arthritis (RA). Less data have been available on altered interrelations of the combined neuroendocrine and immune ...
Mesenchymal stromal cells (MSC) control excessive inflammation and create a microenvironment for tissue repair protecting from chronic inflammation and tissue fibrosis. We examined the molecular mechanisms of MSC immunomodulatory function in mixed cultures of human adipose-derived MSC with lymphocytes. Our data show that MSC promote unstimulated lymphocyte survival potentially by an increase in...
Primary Biliary Cirrhosis (PBC) is considered an autoimmune disease characterized by immune-mediated destruction of the intrahepatic bile ducts and its characteristic serologic marker, the anti-mitochondrial antibody (AMA). Several factors were proposed to clarify the pathological and immunological mechanisms of PBC. Immunological reaction with a bacterial or a viral association was identified ...
Elevated levels of the cytokine TL1A is associated with several autoimmune diseases e.g. rheumatoid arthritis and inflammatory bowel disease. However, the exact role of TL1A remains elusive. In this study, we investigated the function of TL1A in a pro-inflammatory setting. We show that TL1A together with IL-12, IL-15 and IL-18 increases expression of the co-stimulatory molecules CD154 (CD40 lig...
Foxp3(+)CD4(+) regulatory T cells (Treg) have a crucial role in controlling CD4(+) T-cell activation, proliferation, and effector function. However, the molecular mechanisms regulating Treg function remain poorly understood. Here we assessed the role of IL-7, a key cytokine regulating T-cell homeostasis, in suppressor capacity of Treg. Using a skin allograft model in which transplant acceptance...
Background: Interleukin-13 binds two receptors. The first is the IL-13Rα1/IL-4Rα heterodimer which also responds to IL-4 ligand engagement, broadly expressed, and canonically associated with type-2 immune signaling. second, IL-13Rα2, referred as IL-13 decoy receptor, negligibly expressed in normal tissues but overexpressed a range of cancers including pancreatic, colorectal, lung tumors. MDNA13...
Fifty years ago Jacques Miller devised a technique to thymectomize neonatal mice to explore the hypothesis that the thymus played a role in the development of immunity. He found that if thymectomized by day 3 postpartum, the mice would develop normally for the first month, but thereafter they underwent a runting syndrome similar to that observed during Graft vs. Host Disease (GvHD) (Miller, 196...
