For immunotherapy to work, T cells must recognize cancerous proteins, known as neoantigens, produced by mutated cells. Research from the Jacks Lab suggests that natural competition between T cells responding to different neoantigens limits the overall ability of T cells to control tumors. The team's findings, published in Cell and discussed on the NIH Director's Blog, demonstrate that therapeutic vaccines targeting neoantigens can alleviate T cell competition and may improve patient response to immunotherapies.
