Engineering T cell memory for antitumor immunity

摘要

Cancer therapy with the T cell growth factor interleukin (IL)-2 is limited by low response rates and toxicity. Multiple protein engineering strategies have attempted to improve IL-2 therapy, typically through enhanced IL-2 receptor (IL-2R) binding. Intriguingly, Mo et al. show that an IL-2R partial agonist may dramatically improve IL-2 responses by altering T cell differentiation.
