food allergies verses intolerance, Th1,Th2.allergens vs. toxins

FOOD ALLERGIES-Th1 and Th2 envolved

The concept that a pure Th2 responce underlies the mechanism of food

allergy has been revisited and supplanted by the theory that immune

disregulation is at work and also involves Th1 cells.

Initiating mechanisms of food allergy: Oral tolerance versus allergic

sensitation. 2007

the normal immune responce to dietary protiens is associated with the

induction of oral tolerance, which refers to an antigen by means of

prior exposure to that antigen via the oral route.

FAILURE TO INDUCE ORAL TOLERANCE MAY RESULT IN THE DEVELOPMENT OF

FOOD HYPERSENITIVITY. ORAL TOLERENCE VERSES SENSITIZATION TO FOOD

PROTIENS ARE DISCUSSED.

(EE) Eosinophilic esophagitis is frequently associated with atopic

disease, including dermatitis and asthma.

data is emerging that atopic skin may play a role in early antigen

sensitization.

We show that that exposure to antigen via the epicutaneous route

primes for marked eosinophilic inflamation in the esophagus triggered

by a single airway antigen challance.

(EE) is associated with skin , bone marrow,blood and large increases

in serum antigen-specific immunoglobulin G1 and E using ovalbumin or

aspergillus fumigatus as the epicutaneous antigen.

CONCLUSIONS; EPICUTANEOUS EXPOSURE TO " ALLERGENS " POTENTLY PRIMES FOR

EE VIA A TH2-DEPENDANT MECHANISM.
