Milk Peptide and Diazepam Comparisons: Similar Mouse Behavior Did Not Mean Identical Neural Patterns
A mouse experiment found anxiolytic-like behavioral effects of a casein-derived peptide alongside brain-marker patterns that differed from diazepam.

A comparator with a different signature
The study tested YLGYL, a fragment associated with alpha-casozepine, in a light-dark box after intraperitoneal administration. It compared behavioral and c-Fos findings with the parent peptide and diazepam. Some behavioral features were similar, but marker modulation differed across several anxiety-related brain regions.
Do not equate behavioral resemblance with replacement
The study did not test ordinary dietary intake, human anxiety treatment, dependence, or long-term safety. Intraperitoneal peptide exposure also differs from eating a food or taking an oral supplement. Similar performance in one behavioral assay does not establish the same mechanism or therapeutic effectiveness. The findings justify investigating how the peptide acts, while leaving clinical efficacy and whether it could replace benzodiazepines unresolved. Different neural patterns are observations, not proof of a safer treatment.
