Immunotherapies have improved outcomes of many patients with cancer, including melanoma. But these therapies work for only a subset of patients. Numerous studies are looking at improving responses, including research focusing on enhancing tumor-infiltrating lymphocytes (TILs). TILs are immune cells in tumors that can recognize and attack the cancer cells but often there aren't enough of them or they're unable to harness a strong enough response to durably suppress tumor growth and spread. Researchers, led by Eric Lau, Ph.D., have identified a relatively natural way to increase the numbers and antitumor activities of TILs. Lau's team demonstrates how L-fucose, a...
