The intestine is colonized by an impressive community of commensals, that has profound effects on the immune funtions. The relationship between gut microbiota and the immune system is one of reciprocity: commensals have important contribution in nutrient processing and education of the immune system and conversely, the immune system, particularly gut-associated lymphoid tissues plays a key role in shaping the repertoire of gut microbiota.
