Aspirin modified dendritic cells are potent inducers of allo-specific regulatory T-cells.

Salicylic acid (aspirin) is a widely used pharmacological agent with immunodmodulatory properties. Dendritic cells are key regulators of the immune response, and are capable of inducing hyporesponsiveness and regulatory activity in CD4+ T-cells. We have demonstrated that aspirin-treated dendritic cells are effective at antigen processing and presentation, and possess a unique potency for inducing regulatory activity in responder T-cells.
