Dendritic cell (antigen-presenting) (DC (full context: antigen-presenting dendritic cell))

Dendritic cells are a heterogeneous group of professional antigen-presenting cells present in tissues throughout the body[1][2][3][4]. They capture, process, and display antigens to T lymphocytes via MHC molecules, serving as sentinels that bridge innate and adaptive immunity. Dendritic cells play an essential role in initiating immune responses, maintaining tolerance to self-antigens, and secreting cytokines/chemokines that coordinate immune responses. Their activity is crucial for effective immunity against pathogens and tumors, but also for regulating inflammation and preventing autoimmunity[1][2][3][4][5].

Drugs that affect dendritic cells usually work by: - Promoting differentiation or expansion of DCs (e.g., cytokines) - Enhancing antigen presentation (e.g., vaccine adjuvants) - Modulating DC activation/maturation state (immunotherapies) - Inducing DC-mediated immune tolerance (investigational approaches)
