[Autoimmune Rheumatic Diseases - Problems of Immunopathology and Personalized Treatment]

By current standards autoimmunity is a complex pathological process based on a violation of tolerance and, consequently, the pathological immune response against its own tissues components (autoantigens) leading to the development of a wide range of autoimmune diseases in humans. In recent years, multiple immune disorders both acquired and/ or congenital (associated with polymorphisms of genes that regulate immune response) have been transcribed. These disorders occur at the cellular and humoral levels: thymus, intestines, peripheral blood immune cells, including T and B lymphocytes, macrophages, dendritic cells, Treg-cells (Treg), components of complement system, cytokines and others. The interaction between the development of autoimmune rheumatic (ARD) and autoinflammatory diseases and syndromes is detected; a classification of immune-inflammatory diseases is designed. The article describes the results of our studies on the treatment of ARD using innovative genetically engineered biological agents and on the research ofpathogenetic mechanisms and diagnostics of ARD based on immunological and molecular biological diagnostic techniques of a wide range of molecular and cellular biomarkers (autoantibodies, inflammatory acute phase proteins, cytokines, chemokines, markers of activation of the vascular endothelium, the components of the complement system, lymphocyte subpopulations, products of metabolism of bone and cartilage tissue, genetic, epigenetic, transcriptomic markers). The approaches to personalized treatment of ARD are presented.
