Control of regulatory T cells is necessary for vaccine-like effects of antiviral immunotherapy by monoclonal antibodies.

Regulatory T cells (Tregs) down-regulate immunity and are associated with chronic viral infections, suggesting that their inhibition might be used to treat life-threatening diseases. Using the FrCasE mouse retroviral model, we have recently shown that short mAb-based immunotherapies can induce life-long protective immunity. This finding has a potentially… (More)
