>Inspiring Target:Interleukin 4 Receptor
Interleukin-4Rα (IL-4Rα), the key receptor of IL-4, has emerged as an ‘inspiring’ target for innovative therapies aimed at treating various inflammatory and oncological diseases. IL-4Rα is a type I transmembrane protein that plays a key role in the molecular pathway that drives a specific immune pattern called type II inflammations.
This pathway is driven by two cytokines: interleukin-4 (IL-4) and interleukin-13 (IL-13). Both cytokines have diverse biological and immunological effects on lymphocytes, dendritic cells and fibroblasts adjustment function. Specifically, these cytokines bind to IL-4Rα to initiate the type II inflammation pathway that includes differentiation of Th2 cells, airway inflammation and mucus production.
IL-4R and cytokines IL-4 and IL-13 are key regulators in humoral and adaptive immunity. This means that an imbalance in either receptor expression or circulating signaling cytokines can be clinically observed. The resultant immune overreaction is initiated by an initial imbalance of TH1 and TH2 differentiation that drives an abnormal secretion of cytokines. Activated Th2 cells release cytokines including IL-4, 13, and 31, which activate downstream B cells to transform and produce immunoglobulin E (IgE) antibodies. In turn, mast cells and basophils are recruited to degranulate and produce inflammatory factors. Simultaneously, the secreted IL-4 and 13 continue to bind to its respective receptors (e. g. IL-4R) that repeatedly promotes TH2 differentiation and subsequent inflammation. This effect is observed through several autoimmune diseases including asthma, eczema, and hay fever, as well as in metastatic tumors.
