Protective Effect of Glycomacropeptide on the Atopic Dermatitis-Like Dysfunctional Skin Barrier in Rats

were detected in the feces of GMP-treated animals, and the acetic acid and butyric acid contents increased in animals prophylactically administered GMP. These results suggest that GMP markedly prevents or reverses skin barrier damage in rat AD-like lesions through a bifidogenic effect that induces fecal SCFA production with prolonged treatment. Our findings provide evidence that GMP may represent an optimum strategy for the therapy of the dysfunctional cutaneous barrier in AD.
