Protective role of short-chain fatty acids on intestinal oxidative stress induced by TNF-α.

Inflammatory bowel diseases (IBDs) are driven by an exaggerated inflammatory response, which leads to a marked increase in oxidative stress. This, in turn, exacerbates the inflammatory process and causes significant cellular and tissue damage. Intestinal dysbiosis, a common observation in IBD patients, alters the production of bacterial metabolites, including short-chain fatty acids (SCFAs), which are key by-products of dietary fiber fermentation.

Buttermilk and Whey as Functional Foods to Ameliorate Clindamycin-Induced Changes in Mouse Intestine: Modulation of Intestinal Motility and Toll-like Receptors Expression.

Antibiotic treatment is one of the main causes of intestinal dysbiosis, leading, in turn, to other intestinal alterations given the multiple relationships of the microbiota with gut health. Whey and buttermilk are two by-products from the dairy industry with numerous bioactive components. This study aimed to assess the potential of two formulas, containing a mixture of lactoferrin, milk fat globule membrane (MFGM), and whey or buttermilk, to reverse the negative effects of clindamycin on gut motility, Toll-like receptors () expression, and oxidative stress in the intestine.

Lactoferrin modulates oxidative stress and inflammatory cytokines in a murine model of dysbiosis induced by clindamycin.

Antibiotics, specifically clindamycin (Clin), cause intestinal dysbiosis, reducing the microbiota with anti-inflammatory properties. Furthermore, Clin can induce alterations in the immune responses and oxidative stress. Lactoferrin, among other activities, participates in the maintenance of intestinal homeostasis and reduces dysbiosis induced by antibiotic treatment.

Whey and Buttermilk-Based Formulas Modulate Gut Microbiota in Mice with Antibiotic-Induced Dysbiosis.

Scope: Diet is one of the main factors that modifies intestinal microbiota composition. The search for foods that can reverse situations of intestinal dysbiosis such as that induced by antibiotics is of great interest. Buttermilk and whey are the main by-products produced by the dairy industry containing bioactive compounds.

The Role of Lactoferrin in Intestinal Health.

The intestine represents one of the first barriers where microorganisms and environmental antigens come into tight contact with the host immune system. A healthy intestine is essential for the well-being of humans and animals. The period after birth is a very important phase of development, as the infant moves from a protected environment in the uterus to one with many of unknown antigens and pathogens.
