title: The incapability of interleukin-4 to induce AP-1 activity in murine mast cells.
abstract: The results presented in this study shed new light on the molecular mechanism responsible for the control of interleukin (IL)-3- and IL-4 mediated mast cell proliferation. By measurements of AP-1 DNA-binding activity, it was found that IL-3 induced such activity while IL-4 did not. This difference in the pattern of AP-1 DNA-binding activity induced by each lymphokine indicates the differential involvement of AP-1 in the different proliferative responses of mast cells to IL-3 and IL-4.
