Achieving remission in rheumatoid arthritis (RA) remains elusive despite current biological therapeutics. Consequently, interest has increased in strategies to re-establish immune tolerance to provide long-term disease suppression. Although dendritic cells (DC) are prime candidates in initiating autoreactive T cell responses, and their presence within the synovial environment suggests a role in generation and maintenance of autoreactive, synovial T cell responses, their functional importance remains unclear. We investigated the contribution made by plasmacytoid DCs (pDCs) in the spontaneous breach of tolerance to arthritis-related self proteins, including rheumatoid factor, citrullinated peptide, and type II collagen observed in a novel arthritis model. Selective pDC depletion in vivo enhanced the severity of articular pathology and enhanced T and B cell autoimmune responses against type II collagen. pDC may offer a net anti-inflammatory function in the context of articular breach of tolerance. Such data will be vital in informing DC modulatory/therapeutic approaches.
