Arginine Could Reinforce Immune Alarm Signals in Cancer and Viral Infections

Arginine deficiency weakens immune surveillance by lowering MHC-1 production, and a modest dietary boost could restore this immune signal. In cell culture and mouse studies of colon cancer and viral infections (influenza and SARS-CoV-2), higher arginine reduced tumors and improved outcomes, hinting that arginine supplementation might complement immunotherapies or help at-risk groups. Since arginine levels decline with age and poor nutrition, this could partly explain increased cancer and infection vulnerability.

Common amino acid arginine slows Alzheimer’s pathology in animals

Japanese researchers found that arginine, a safe and inexpensive amino acid, reduced amyloid-β aggregation, decreased brain inflammation, and improved behavior in fruit flies and mice models of Alzheimer’s disease. The effects appear to come from interfering with protein misfolding rather than lowering production. While promising and eligible for repurposing, the work is preclinical and dosing differs from dietary supplements, so larger preclinical and human studies are needed before clinical use.

Arginine in Saliva May Turn Mouth Biofilms from Detrimental to Protective

A Danish study from Aarhus University suggests that increasing arginine levels in saliva can shift mouth biofilms from acid-producing to protective, reducing tooth decay risk. In a real-world denture-biofilm setup, arginine treatment raised pH after sugar exposure, altered the bacterial and sugar composition, and reduced acid-producing Streptococcus populations, though responses varied among individuals. Arginine appears safe and could be explored as an additive in toothpaste or mouthwash, warranting further clinical research.
