IL-4 Detection (CAT#: STEM-MB-0273-WXH)

Introduction

IL-4 is a cytokine secreted by type 2 T helper cells, mast cells, and basophils. It has an immune function and is an anti-inflammatory factor. Besides, it also plays a central role in regulating antigen-stimulated initial T cell differentiation, causing T cells to produce cytokines such as IL-10, IL-14, and inhibiting CD4+ T cells from secreting IFN-γ. It can only exert its biological activity if it binds to a specific receptor on the membrane of the target cell.




Principle

IL-4 is a dense, hydrophobic, spherical protein consisting of 129 amino acid residues. The biological effects of IL-4 are mediated by binding to its receptors, which are distributed in T cells, B cells, thymocytes, macrophages, bone marrow cells, macrophages and other cells. After binding to its receptor IR-4R, it can play a variety of biological functions, such as participating in the differentiation of primitive helper T cells, clearing parasites in the body, and triggering hypersensitivity. There are two types of IL-4 receptor (IL-4R): type I receptor complex IL-4Rα / IL-2Rγc and type II receptor complex IL-4Rα / IL-13Rα1. Type I receptors are mainly expressed on the surface of hematopoietic cells, and type II is often expressed on the surface of other cells such as non-hematopoietic cells and tumor cells.
