Wheat allergy is characterized by the activation of T helper type 2 (Th2) cells which are necessary for humoral immunity and play a pivotal role in ทางเข้า ufabet coordinating the immune response. Such activation results in immunoglobulin E and non-immunoglobulin E mediated reactions (the latter representing much less understood pathophysiological mechanism).
