Over the last few years food allergies have become a clinical problem of prime importance in children. It is clear that food allergy is most frequent in infants. Food macromolecules are absorbed at every age, but most evidently during the first months of life. Many facts show that the barrier of the gastro-intestinal tract against harmful agents present in the intestinal lumen is not completely developed in infants and especially in newborns. Deficiencies in the secretory system for TgA contribute to greater permeability of the intestine for allergenic macromolecules in early childhood.

UI	MeSH Term	Description	Entries
D007071	Immunoglobulin A, Secretory	The principle immunoglobulin in exocrine secretions such as milk, respiratory and intestinal mucin, saliva and tears. The complete molecule (around 400 kD) is composed of two four-chain units of IMMUNOGLOBULIN A, one SECRETORY COMPONENT and one J chain (IMMUNOGLOBULIN J-CHAINS).

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D008894	Milk Proteins	The major protein constituents of milk are CASEINS and whey proteins such as LACTALBUMIN and LACTOGLOBULINS.
