In Individuals with a Peanut Allergy, Mild Allergic Responses Are

Multiple Choice

In individuals with a peanut allergy, mild allergic responses are those that involve a single site, typically a skin reaction such as hives. More severe allergic reactions generally involve multiple tissue sites, such as the skin, oral mucosa, airway mucosa and gastrointestinal tract. Given two groups of allergic patients, one with only skin responses, and the other with 3-4 different tissue sites involved, one would expect that:

A) Patients with the severe allergic responses would have higher concentrations of allergen-specific IgE.
B) Patients with mild allergic responses would have fewer mast cells in the majority of their mucosal tissues.
C) Patients with severe allergic responses would also have allergies to several other substances, such as bee venom or pollen.
D) Patients with severe allergic responses would have reduced expression of antioxidant enzymes, such as glutathione-S-transferases.
E) Patients with mild allergic responses would have higher numbers of CD4+ T_reg cells.
