The role of the gut mucosal immunity in the development of tolerance against allergy to food.

Abstract:

PURPOSE OF REVIEW:To provide an overview on the role of gut mucosal immunity in the development of tolerance against allergy to food. RECENT FINDINGS:The gastrointestinal tract, through innate and specific immunologic factors, acts as a defense against ingested antigens. In addition to the mucous membrane integrity and digestion, numerous specific immunologic cells and mediators orchestrate such defensive mechanisms. In case of food antigens, the outcome is usually in favor of tolerance. Defects in that barrier, however, can lead to the development of aberrant immunologic responses, including hypersensitivity reactions. SUMMARY:The prevailing evidence is that healthy mucosal immunity plus appropriate feeding regimen during early infancy are in favor of food tolerance. However, in addition to genetic predisposition, development of allergy is facilitated by defects in the gut barrier (immune or nonimmune) and the food allergen load.

  • The role of indoor allergen exposure in the development of sensitization and asthma.

    abstract::The role of indoor allergen exposure in the development of sensitization and asthma remains a subject of controversy. From a number of cross-sectional and longitudinal studies we can conclude that there is a very close association between allergen exposure and the sensitization of an individual. The dose-response rela...
