Immunoglobulin A
Food MicrobiologyA Soluble Fiber Diet Increases Bacteroides fragilis Group Abundance and Immunoglobulin A Production in the GutImmunoglobulin A (IgA) is essential for defense of the intestinal mucosa against harmful pathogens. Gut microbiota impact IgA production, but the specific species responsible for IgA production remain largely elusive. Previous studies have shown that IgA and Bacteroidetes, the major phyla of gut microbiota, were increased in soluble high-fiber diet-fed mice. We show here that the levels of IgA in the gut and the expression of...
