The therapeutic effect of DLE is related to an immune modulatory effect that changes innate signaling pathways, such as Toll Like Receptors, and Nuclear Factor -kappa B; production of cytokines might also be modified with the use of DLE, including Tumor Necrosis Factor a, Interleukin (IL)-6, and induction of Interferon-g secretion, driving immune response to a T-helper Th1 immune-regulatory response, and thus helping to reduce allergy symptoms.
