Study Finds Arginine Supplementation May Enhance Immune Response Against Cancer and Viruses
Research from Rockefeller University suggests that the amino acid arginine, commonly found in protein-rich foods and supplements, may significantly enhance the immune system's ability to fight cancer and viral infections. The study found that low levels of arginine can impair the production of MHC-1 proteins, which are crucial for the immune system to detect and respond to cancer cells and viruses. Supplementing with arginine was shown to improve outcomes in mice models of influenza and COVID-19, suggesting potential therapeutic benefits. The research highlights the role of diet in modulating immune responses and suggests that arginine supplementation could be a simple strategy to boost immunity, particularly in older adults or those with low arginine levels.
