Researchers report that mice genetically deficient in a mitochondrial antiviral protein (MAVS) experienced significant alterations in gut microbiota, a condition termed dysbiosis, compared with wild-type mice, leading to increased intestinal permeability and bacterial migration within the body upon inflammatory challenge, as well as increased susceptibility to the murine model of human allergic contact dermatitis; the results suggest a mechanistic link between gut microbiota and allergies.
