Dendritic cell and co-stimulatory molecule targeted therapy for autoimmune diseases: a review of the newly implemented strategies

Dendritic cells (DCs) play an important role in the formation of the immune response, and they are involved in the pathogenesis of autoimmune diseases. Targeting DCs has thus emerged as a new therapeutic modality in the management of inflammatory and autoimmune diseases. DCs can be manipulated ex vivo and then injected back into humans to suppress the immune response. They can also be manipulated in vivo by delivering specific molecules into the DCs. Co-stimulatory molecules that shape DCs interaction with T cells can also be targeted to suppress immunity. This review tackles the latest advances in each of the 3 presented approaches.
