This amino acid may help the body fight tumors and viral infections

medicalxpress - The amino acid arginine helps keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes. It's produced by our bodies and found in common high-protein foods. Low levels of arginine are associated with a…

AI Summary: New research implicates the amino acid histidine in modulating immune and tumor biology, suggesting it may enhance anti-tumor responses and antiviral defenses in preclinical studies. Scientists report mechanistic insights that could inform future therapeutic strategies, although translation to patients will require careful testing—because promising mouse data still need to pass the human audit.
