interleukin-4 (il-4) is produced by t-helper cells type 2 (th2) and induces ige synthesis. t-helper cells type 1 (th1) produce interferon-gamma (ifn-gamma) which suppresses th2 and reduces il-4 induced ige production. in this :;tudy , we demonstrated that the levels of specific ige in the serum of atopic children (n=20) were elevated while il-4 production was increased and ifn-gamma secretion w...
