Mechanisms of Formation and Persistence of Ige Products and Potential Innovative Means of Therapy for Allergic Pathologies

Abstract

The proposed review is devoted to the analysis of the main mechanisms of the formation of IgE-producing cells in the body and a brief review of the main, most striking candidate agents for use in innovative methods of therapy for IgE-dependent pathologies. Data are presented according to which the role of IgE+ plasma cells and various subpopulations of memory B-lymphocytes in the formation and persistence of the state of sensitization to a harmless allergen differs depending on the model system used or the clinical case under study. Therefore, drugs that target signaling pathways involved in the regulation of both plasma cells and memory B-lymphocytes are especially promising in the treatment of allergic diseases. The authors conclude that the components of the cellular response to oxidative stress and related genotoxic stress and ER stress are the most promising as such targets, since (a) all of them directly or indirectly affect the processes that regulate both of these subpopulations; b) are involved in the process of formation and maintenance of local allergic inflammation. The review presents data pointing to the particular promise of using nanoparticles of noble metals and complexes of rare earth metals of lanthanides in this regard, due to their ability to induce long-term effects in small doses due to changes in the properties of innate immunity cells and long-term accumulation in the body.
