🧬 Arginine helped mice fight cancer and flu Restricting arginine, which happens naturally in cancer and infection, blocks a cell's ability to present antigens. Boosting it in mice cut colon tumours and improved flu outcomes. 🔗 www.cell.com/cell/abstrac... #Immunology #Cancer 🧪

Dietary arginine drives codon-dependent MHC class I translation and improves immunity in colon tumorigenesis and respiratory viral infection

Arginine availability regulates arginyl tRNA levels and codon-dependent translation of MHC class I, tuning antigen presentation and shaping anti-viral and anti-tumor immunity.
