Dietary arginine drives codon-dependent MHC class I translation and improves immunity in colon tumorigenesis and respiratory viral infection.
Cell·July 30, 2026·PMID 42532044
Why it mattersAmino acid availability, particularly arginine, directly influences immune surveillance by modulating MHC class I translation. This reveals a mechanistic link between dietary arginine and anti-tumor or anti-viral immunity, suggesting that arginine status could be a modifiable factor in cancer and infection outcomes.
