Interleukin4 (IL4) is a cytokine with several important functions in the immune system. It primarily helps activate B cells and produce antibodies, especially IgE antibodies related to allergies. It also promotes the differentiation of T helper cells into Th2 cells, supporting humoral immune responses. Additionally, IL4 can help suppress inflammation in certain situations, maintaining immune balance. It is mainly secreted by activated T cells, mast cells, and basophils, and serves as a key target for interventions in various diseases, including allergies and asthma. Due to its crucial role in immune regulation, IL4 has been a significant focus in immunology research.

The IL4RA protein, also known as the interleukin-4 receptor alpha chain, is an important cell surface receptor primarily involved in regulating the immune system. When it binds with interleukin-4 (IL-4), it triggers signaling pathways that promote T cell differentiation and B cell proliferation. IL4RA plays a significant role in allergic reactions and asthma, and its gene polymorphisms are associated with susceptibility to various immune-related diseases.
