Intestinal Integrity with the Probiotic Bifidobacteria.

Hsieh found in a recent study that certain strains of Bifidobacteria reduce epithelial barrier disruption in the intestines. It is believed that intestinal barrier dysfunction leads to a number of diseases including inflammatory bowel disease. In this study, the author found that the actions on TNF-a were achieved by the whole Bifido cell. This shows, according to Hsieh, that bacterial metabolites must be produced that act to reduce TNF-a. He also found that different strains of Bifidobacteria achieve intestinal tight junction integrity better than others. This reinforces what I said in a previous post that more research is needed  on the benefits of different strains of probiotics.
