- Which of the following statements regarding celiac disease is/are TRUE?A. Celiac disease, also known as a wheat allergy, is an inappropriate immune response that specifically targets only wheat products containing gluten.B. In a celiac patient, both cellular and humoral immune responses result in the loss of the villous epithelium of the small intestine.C. The best treatment for celiac disease is immunosuppressive drugs, such as methotrexate, that inhibit the body’s inappropriate ‘allergic’ response to gluten.D. Even if you don’t have celiac disease, adopting a gluten-free diet has numeroushealth benefits because gluten is toxic to the GI tract.E. Diagnosis of celiac disease can be made by serological testing for the presence of anti-gliadin antibodies.Match the following antibodies with the correct definition. _____ IgD a. Antibody found in secretions _____ IgM b. Most common antibody; crosses the placenta _____ IgG c. Antibody involved in allergies and parasitic _____ IgA infections _____ IgE d.
