Autoimmunity And Immune Tolerance Induction In Dendritic Cells Through Compared to other apcs such as macrophages and b cells, dcs are considered the most efficient apcs capable of efficiently processing and presenting exogenous antigens on both mhcii and mhc i molecules to naïve cd4 and cd8 t cells, respectively, thus initiating the adaptive immune response. In this review, we explore the heterogeneity and tissue specialization of dcs, emphasizing their roles in immune homeostasis. we highlight molecular and metabolic mechanisms that confer tolerogenic properties to dcs, as well as specific dc subsets recently identified as tolerogenic.
Yin Yang Regulation Of Tolerance And Autoimmunity By Dendritic Cells Induced tolerogenic dendritic cells are a powerful immunotherapy for autoimmune disease that have shown promise in laboratory models of disease and early clinical trials. Toldcs can promote tolerance towards different immune cell types involved in autoimmunity via contact dependent interactions and by secreting pleiotropic cytokines and metabolites. Peripherally induced t cell tolerance is necessary to extend the maintenance of immune homeostasis and to block autoimmune responses. dcs are key inducers of peripheral tolerance. the tolerogenic functions of dcs can be directed and enhanced by in vivo targeted delivery of defined t cell antigens. Through costimulatory molecules and other factors, dc are involved in the maintenance of peripheral tolerance through modulation of the immune response. this modulation occurs both.

Through costimulatory molecules and other factors, dc are involved in the maintenance of peripheral tolerance through modulation of the immune response. this modulation occurs both. This review explores the phenotypic and functional heterogeneity of dcs and their specialized roles in regulating the immune response, with a focus on pathways that confer tolerogenic properties to dcs. Dendritic cells (dcs), first identified by ralph steinman in 1973 as the "professional sentinels" of the immune system, serve as the critical bridge between innate and adaptive immunity by orchestrating immune surveillance, antigen presentation, and t cell priming. Immune tolerance is necessary to prevent the immune system from reacting against self, and thus to avoid the development of autoimmune diseases. in this review, we discuss key findings that position dendritic cells (dcs) as critical modulators of both thymic and peripheral immune tolerance. Dendritic cells induce peripheral tolerance or immunity by directing the fate of antigen specific t cells. presentation by steady state dcs of weakly agonistic self peptides maintains tonic ag receptor signaling and responsiveness of both normal and self reactive t cells.
