Core Tip
Core tip: The effect of the gut microbiota on the immune responses is not limited to the gut. On the other hand, autoimmune diseases, such as inflammatory bowel disease, are associated to different degree of dysbiosis involving different bacterial genera. Using a colitic mouse model, we aimed to evaluate the impact of anti-tumor necrosis factor α (TNFα) therapy on the intestinal immune system and gut microbiota concurrently. Healthy mice treated with anti-TNFα showed similar histological, microbial and immune features of untreated colitic mice, a lymphomononuclear infiltrate both at day 5 and 12 at hematoxylin and eosin staining, an increase of type 1 helper T lymphocytes and type 17 helper T lymphocytes at day 12, and finally increase of Enterococcaceae at day 5, a decrease of Bacteroides and Clostridiaceae at day 12.
