Dendritic cells (DCs) play a crucial role in bridging innate and adaptive immune responses. They are widely distributed in various tissues and organs, including the eyes. In the ocular context, permanent DCs are present at the peripheral edge of the retina and the peripapillary area in an immature state. However, during the inflammatory process, DCs become activated and contribute to the development of uveitis. This review focuses on introducing the characteristics and status of DC-induced uveitis, exploring factors that can influence the status of DCs, and discussing feasible methods for treating DCs in both experimental autoimmune uveitis animal models and humans. It emphasizes the importance of further research on molecular pathways and signaling pathways that regulate the function of DCs. For example, investigating molecules such as cytotoxic T-lymphocyte-associated protein 4, which inhibits the B7-CD28 co-stimulatory interaction, can help improve immune homeostasis. The aim is to identify new therapeutic targets and develop targeted strategies for DCs, such as DC vaccine therapy or the use of immune modulators. These approaches can be tailored to the immune characteristics and disease manifestations of individual patients, enabling personalized treatment strategies. This may include the personalized design and precise medication of DC therapy, with the ultimate goal of improving treatment efficacy while minimizing adverse reactions.
