Document Summary

Memory cells: subsequent exposure produces reaction. Food can give allergy or intolerance: allergy, immune system reacts to the food, intolerance, substances in food produce adverse reaction. Hygiene hypothesis for allergy: we are too clean, in the developed world, we don"t get sick anymore, so the less disease we get, the more allergies we get. Allergy rewuires prior exposure: involves immune system memory, hypersensitivity on 1st exposure, unknown previous exposure. Mast cel display ige antibodies: allergen contacts te ige molecules, antibody can send a chemical signal to the inside of the amss cell, mast cell degranulation releases histamine, cell is dying, histamine produces the allergy symptoms. Managing allergy: avoidance, antihistamines, decongestants, immune modulators, immunotherapy. Allergy tests look for reactions: inject different amount of immunogenic materials and lay it out on your back and look for an immune reaction, are able to se what your allergic to based on where the reaction occurs.
