00:00Researchers have uncovered a hidden link between nutrition and immunity.
00:04A common amino acid called arginine may play a key role.
00:08Rockefeller University scientists studied how low arginine affects immune defenses.
00:13They found that shortages can disrupt MHCI proteins.
00:16These proteins help T-cells identify cancerous and virus-infected cells.
00:21When arginine levels dropped, this warning system became weaker.
00:25Researchers tested the effect in mice with colon cancer.
00:29Higher arginine diets restored MHCI production and reduced tumor growth.
00:33The team also studied influenza and SARS-CoV-2 infections.
00:37Mice, given more arginine, developed milder symptoms.
00:41Researchers say the findings could eventually support cancer immunotherapy.
00:45They may also help guide future antiviral treatments.
00:49But there is an important limitation.
00:51The research was conducted mainly in cells and mice.
00:55Clinical trials are still needed to know if it works in people.
00:58For now, scientists say, the findings reveal a potentially important role for arginine in immune defense.
