Role of Dendritic Cells in the Rheumatic Diseases Pathogenesis: Review

Dendritic cells (DCs) are professional antigen presenting cells that can as stimulate immune response as suppress immune inflamma tion. Recently the role of DCs in the pathogenesis of autoimmune diseases and the possibility of their application as diagnostic markers and methods of treatment has been studied more and more. It was shown that subpopulations DCs play different role in pathogenesis various autoimmune diseases. Thus, pathogenesis of rheumatoid arthritis and ankylosing spondylitis is associated with activity of myeloid DCs and their possibility to present arthritogenic peptides to T-cells. While plasmocytoid DCs are more important in pathogenesis systemic lupus erythematosus and systemic sclerosis. The review presents the results of the latest registered clinical trials about applications DCs in different autoimmune diseases as well as current ideas about functional features DCs during autoimmune diseases. The existing data confirm their possible use as well as the safety of DC in treatment.
