Cytokines involved in class switching
WebThe antibody class switch is critically dependent on the type of cytokine that is present. Various cytokines, such as IL-4, IL-5, IFN-gamma, and TGF-beta, are known to be responsible for class switching. At a certain stage, the cell will lose its ability to undergo a switch to a class that has been generated before.
