Title
Interleukin-2 treatment of tumor patients can expand regulatory T cells.
Authors
Beyer, Marc

Interleukin-2 has been widely used in the clinics in anticancer therapy, yet evidence has accumulated that the major drawback, limiting clinical efficacy, is the expansion of regulatory T cells, which aggravates immunosuppression.
