Interleukin 4 (IL4) Antibody (Biotin)

Background

Interleukin-4 (IL4) is a crucial cytokine in the immune system, primarily involved in the regulation of humoral (antibody-mediated) immune responses and the differentiation of immune cells. It is produced by several immune cells, including activated CD4+ T cells (specifically Th2 cells), mast cells, basophils, eosinophils, and, to a lesser extent, CD8+ T cells. IL-4 is a member of the interleukin family of cytokines and plays a key role in driving the differentiation of naïve helper T cells (Th0) into Th2 cells, which are central to the adaptive immune response. This cytokine is also vital in inducing B cell class switching to immunoglobulin E (IgE), a process essential for allergic reactions. In addition to its immune-regulatory functions, IL-4 is heavily involved in allergic diseases such as asthma, allergic rhinitis, and atopic dermatitis. IL-4 mediates a wide range of biological effects that contribute to inflammation, allergy, and immune system modulation.
