IL4

IL4 is a cytokine that plays a central role in regulating the immune system, especially in promoting the differentiation of naïve T-cells into Th2 cells. It is essential for the immune response to allergens and in the regulation of asthma and allergy responses. IL4 promotes the production of IgE antibodies, which are key in allergic reactions. It also modulates the activity of various immune cells, including B-cells and T-cells. IL4 has been implicated in the pathogenesis of several inflammatory diseases, including autoimmune conditions and allergies. It binds to the IL4 receptor to activate intracellular signaling cascades that regulate immune function.
