IL4 is expressed by T cells, NK cells, and mast cells, and is an important regulator of humoral and adaptative immunity. It stimulates activated B cells, and induces their differentiation into plasma cells and their class switch to immunoglobulin E, as well as promoting class II MHC expression. In immuno-oncology, IL4 induces the differentiation of naïve T cells into TH2 cells, which in turn produce IL4 and thus create a positive feedback loop. IL4 is also involved in the development of airway inflammation and allergic asthma.
The 4 Parameter Logistic (4PL) curve is commonly recommended for fitting an ELISA standard curve. This regression enables the accurate measurement of an unknown sample across a wider range of concentrations than linear analysis, making it ideally suited to the analysis of biological systems like cytokine releases.
