Abstract. Over the past decade a population of so–called “regulatory T cells” (Treg cells) has been linked to the prevention of autoimmunity. In this review we discuss the molecular mechanisms of Treg cells development and function including the identification of the unique molecular marker of Treg...

A novel therapeutic approach, inverse vaccination, is being developed to combat autoimmune diseases and other inflammatory conditions. It aims to educate the immune system to recognize self-components as innocuous and stop reacting against them. Inverse vaccination, also referred to as tolerogenic v...

Atherosclerosis is a chronic inflammatory disorder involving innate and adaptive immunity process. Effector T cell (Teff) responses promote atherosclerotic disease, whereas regulatory T cells (Tregs) have been shown to play a protective role against atherosclerosis by down-regulating inflammatory re...

The revue includes the contemporary information about regulatory T cells (Treg), that regulate the inflammatory responses and adaptive immune response in defense against infection. The different populations of Treg are described, their activation mechanisms, and the mechanisms of influencing target...

Autoimmune diseases  and  complications  after  transplantation  operations are  major   public health  problem, as they often  lead to deterioration in the quality  of life, reduce  work capacity  and  disability in the  population. To date, the  induction of antigen-specific tolerance is the  prom...

Abstract. Present work aims to investigate functioning of the regulatory T-cells with suppressor activity in surgical sepsis. It has been shown that the septic patients with decreased T cell proliferation are characterized by enhanced relative contents of СD4+СD25+ lymphocytes, including СD4-CD25hig...

Regulatory T cells (Tregs) is a CD4+ lymphocyte subpopulation that maintains autotolerance by suppressing the activity of autoreactive lymphocytes. There is a hypothesis that functional defects or a smaller number of Tregs underlie the pathogenesis of a number of autoimmune diseases. The paper consi...

Hepatocellular carcinoma (HCC) constitutes more than 90% of the primary tumor of the liver. Metabolic reprogramming is decisive in promoting HCC development. The new metabolic program drives the surrounding immune cells to an immune suppressive commitment, enabling tumor survival. The enhanced metab...

The work analyzed subpopulation structure of peripheral blood T-regulatory cells (T-reg) and production of cytokines with immunosuppressor activity (IL-10, TGF-b) in vitro in patients with disseminated pulmonary tuberculosis, depending on the sensitivity of Mycobacterium tuberculosis to anti-tubercu...

The immune processes associated with the formation of resistance to pathogens in the intestine depend on the microbiome. The maintenance of homeostasis in the intestine is provided by regulatory T-cells. In inflammatory bowel disease (IBD), both a disturbance of the T-regulatory function and changes...

In the article is consider reasons of the second immunodeficiency, attendants flow the infectious diseases of viral kind. It is established, that molecular machinery make conditional viral-induce immunosuppression, in those number role in her forming CD4+ CD25+ T-lymphocytes, witch known as regulato...

Children and teenagers aged 10-17 years old with juvenile arthritis (n=99), with reactive arthritis (n=21), with systemic sclerosis (n=16), with systemic lupus erythematosus (n=14) and conditionally healthy (n=32) are investigated. It’s revealed by the method of flow cytometry that quantity of regul...

The article presents a review of the literature. The article presents the published data on the role of reticular epithelial cells in the formation of specific microenvironment in the cortex and medulla of thymic lobules. Thymic microenvironment plays a key role in T-cell differentiation. Discusses...

Immunotherapy has emerged as a cornerstone strategy for augmenting therapeutic efficacy in acute myeloid leukemia (AML). The immunosuppressive AML microenvironment, characterized by profound immune dysfunction, critically impairs anti-leukemic immune surveillance. This immunologically hostile niche...

In this review we discuss the mechanisms of human immune response modification by helminth in bronchial asthma. Helminth invasion causes increase of level to regulatory T-cells and to suppression of an allergic inflammation in bronchial asthma. Antihelminth therapy leads to decrease of level Treg ce...

Subpopulation structure of regulatory T-cells of peripheral blood in patients with newly diagnosed pulmonary tuberculosis depending on the clinical form of disease and sensitivity of Mycobacterium tuberculosis to anti-tuberculosis drugs have been analyzed in this work. It has been shown that in form...

Objective: to analyze the levels of CD3+, CD3+CD4+, CD3+CD8+, and CD3-CD56+ T lymphocytes, FoxP3+ regulatory T cells (Treg), and CD19+ B lymphocytes in patients with early and advanced rheumatoid arthritis (RA). Subjects and methods. The investigation enrolled 45 patients previously untreated with m...
