A shortage of one common nutrient could help cancer cells and viruses hide from the immune system. Researchers at Rockefeller University found that a shortage of arginine, an amino acid obtained from food and produced by the body, can interrupt the cellular machinery needed to make MHC-I proteins. These proteins act as a surveillance system, [...]

Triple-negative breast tumors may hijack immune cells to attract nerves that help the cancer grow. Nerves growing through a tumor may help an aggressive breast cancer survive, expand, and resist treatment. University of Oklahoma researchers have identified how triple-negative breast cancer may recruit those nerves by turning the body’s own immune cells into messengers. Networks [...]
