description Intestinal mucosa integrates primary digestive functions with immune functions such as pathogen surveillance, antigen transport and induction of mucosal immunity and tolerance. Intestinal adaptive immunity is elicited in organized mucosa-associated lymphoid tissue (O-MALT) that is composed of antigen-presenting cells and lymphocytes and achieved by effector cells widely distributed in mucosa (diffuse MALT or D-MALT). Interaction between the intestinal epithelium, the O-MALT and the diffuse MALT plays a critical role in establishing an adequate immune response. In regions associated to O-MALT, lympho-epithelial cross-talks lead to acquisition of a specific epithelial phenotype that contributes to O-MALT organization and functionality. Beyond the expression of several innate immune functions, the intestinal epithelium may directly take up and present antigens due to the expression of major histocompatibility complex (MHC) and MHC-related molecules. A complex genetic program that will be outlined in the present review controls the development of immune functions of the intestinal epithelium. The effect of environmental signals on the modulation of this ontogenetic program during development and neonatal life, from bioactive components of amniotic fluid to lactation and bacterial colonization, will be discussed.
