... properties of the intestinal epithelial barrier in humans are largely unknown. • We report that the aging gut is characterized by higher levels of the cytokine IL-6 that in part affects intestinal permeability. Furthermore, aging is associated with an impaired intestinal innate immunity to microbial...

... in intestinal permeability with changes in intestinal biopsy at various intervals after commencing a GFD. Intestinal permeability was measured by lactulose/rhamnose absorption from 1 week to 24 months after commencing a GFD. Intestinal morphometry was measured by villus area, crypt length and mitotic count per...
