Abstract Background Autoimmunity is used to cause by impairment of adaptive immunity alone, whereas autoinflammatory was originally defined as a consequence of unregulated innate immunity. So, the pathogenetic mechanisms of autoimmune diseases were well-thought-out to be mediated by B and T lymphocytes. Whereas, autoinflammatory diseases were defined as unprovoked times of inflammation with the absence of a high titre of autoantibodies. Main body of the abstract Autoimmune and autoinflammatory diseases were split into two groups, but considering the similarities, it can be considered as only one group of diseases with a large immune pathological and clinical spectrum which involves at one end pure autoimmune diseases and the other pure autoinflammatory diseases. Conclusions We can safely conclude that there is bridging between autoinflammatory and autoimmune diseases.

Background:: The immune system is designed with great care to distinguish self from non-self, as exhibited by immune responses to different pathogens. Furthermore, the immune system has the capacity to distinguish between self from altered self in case of autoimmune diseases like cancer. Developing tumors bypass the immune system mechanism which restrains selfreactive responses. Immunotherapy is a coherent means since the immune system can eliminate a number of antigens derived from the genetic constitution of B and T lymphocytes. Our understanding of the immune system has developed a great deal. Conclusion:: This review is focused not only on the mechanism by which the immune system protects us but also on the ways in which it can inflict the body and how to modulate it with therapy. Thus, understanding the interaction of a tumor with the immune system provides insights into mechanisms that can be utilized to elicit anti-tumor immune responses. Here, we have recapitulated the function of the tumor microenvironment and immune checkpoints.

To recognize pathogens, B and T lymphocytes are endowed with a wide repertoire of receptors generated stochastically by V(D)J recombination. Measuring and estimating the diversity of these receptors is of great importance for understanding adaptive immunity. In this chapter we review recent modeling approaches for analyzing receptor diversity from high-throughput sequencing data. We first clarify the various existing notions of diversity, with its many competing mathematical indices, and the different biological levels at which it can be evaluated. We then describe inference methods for characterizing the statistical diversity of receptors at different stages of their history: generation, selection and somatic evolution. We discuss the intrinsic difficulty of estimating the diversity of receptors realized in a given individual from incomplete samples. Finally, we emphasize the limitations of diversity defined at the level of receptor sequences, and advocate the more relevant notion of functional diversity relative to the set of recognized antigens.

How does the immune system respond to such diverse threats, including viruses never encountered previously by us as a species? The inherent diversity in the immune system can be explained by examining how the adaptive immune system is built, in particular the receptors on B and T lymphocytes. ‘The adaptive immune system: a voyage of (non-)self-discovery’ describes B and T cells, receptors, and the creation of antibodies. Antibody genes are not created as a single unit but are made up from smaller parts, generating many more possible combinations. The antibodies that are created from the genetic template are further honed, becoming highly specific to their target.

With the continuous development of immunotherapy, researchers have paid more attention to the specific immune regulatory mechanisms of various immune responses in different diseases. As a novel and vital innate immune signal pathway, the cGAS-STING signal pathway activated by nucleic acid substances, interplays with other immune responses, by which it participates in regulating cancer, autoimmune and inflammatory diseases, microbial and parasitic infectious diseases, and other diseases. With the exception of its role in innate immunity, the growing list of researches demonstrated expanding roles of the cGAS-STING signal pathway in bridging the innate immunity (macrophage polarization) with the adaptive immunity (T lymphocytes differentiation). Macrophages and T lymphocytes are the most representative cells of innate immunity and adaptive immunity, respectively. Their polarization or differentiation are involved in the pathogenesis and progression of various diseases. Here we mainly summarized recent advanced discoveries of how the cGAS-STING signal pathway regulated macrophages polarization and T lymphocytes differentiation in various diseases and vaccine applications, providing a promising direction for the development and clinical application of immunotherapeutic strategies for related diseases.

A review article is an aftermath of the 11th International Congress on Autoimmunity and First Academy of Autoimmunity, happened 14th to 20th May, 2018 in Lisbon. The first part of paper discusses the formation, main problems and prospects for the development of Autoimmunology as a new integral branch of fundamental and clinical Medicine engaged in the research, diagnosis, treatment and prevention of autoimmune diseases of various organs and systems, totally circa 90 of them. A summary of all lectures conducted during the Academy of Autoimmunity is given, including a discussion of the newest and controversial aspects of the development of the modern concepts of the immune system, autoimmunity and autoimmune pathology. Article reviews data on the current problems of Immunology associated with the use of large databases of clinical and laboratory findings and extrapolation of animal experimentation data to humans. The newest ideas about congenital immunity, including the populations of innate lymphoid cells, on the role of various groups of receptors of the innate immunity system, on the participation of the mechanisms of innate immunity in pathogenesis of autoimmune disorders are highlighted. Modern concepts of antigen presentation are offered, including classification of dendritic cells, alternative pathways of macrophage activation, as well as on costimulatory and inhibitory interactions of ligands and receptors of lymphocytes and antigen-presenting cells. The latest data about the subpopulations of T lymphocytes and their role, including the functions of Tfh cells and the relationships of these subpopulations with various immune responses are highlighted. Influence of microbiota on T cell subpopulations is discussed. The main regularities of the phenomenon of immunological memory are formulated. The questions of antibody production and B lymphocyte functions are considered taking into account recently discovered mechanisms of intracellular penetration of immunoglobulins and details of affinity maturation of lymphoid clones. The new therapeutic approaches in the treatment of autoimmune diseases associated with influences on B and T lymphocytes are described. Mechanisms of central and peripheral autotolerance have been highlighted, taking into account data on the function of the AIRE gene and T regulators. The role of T regulators in placentation is considered. The role of interleukin-2 and its recombinant analogues in immune interactions is interpreted in a new way, taking into account not only their immunostimulating, but, under certain conditions, immunosuppressive potential also. Considerable attention has been paid to the inhibitory receptors of T lymphocytes and to immuno-biotherapeutic effects on them. The history and current status of Oncoimmunology and the use of blockers of inhibitory T lymphocyte receptors in Oncology, including the side effects of treatment with check-point inhibitors, are briefly discussed. Information was given on the held on 21-23 September 2018 2nd Academy of Autoimmunity in St. Petersburg.
