Because inflammatory factors such as interleukin (IL)-4, IL-5, IL-13, IL-15, eotaxin-3 [62, 63], IL-10, tumor necrosis factor (TNF)-α, and interferon (IFN)-γ [64], are found to be elevated in non-IgE-mediated food allergy, it is also our future interest to examine the changes in these inflammatory factors in our mouse model. Here, IL15 is linked to food allergy.
