To study the effects of cytokines on human IgE antibody forming cells (AFCs), log phase U266 myeloma cells (3 × 10 3 /ml), which secrete immunoglobulin E (IgE), were cultured for 0‐24 h with and without cytokine or with or without antibodies against various cytokines. The numbers of IgE AFCs were determined in ELISPOT assay. We found that interleukin‐6 (IL‐6) suppressed (to 95%) whereas anti‐IL‐6 increased (to 148%) the numbers of IgE AFCs and that both worked in a dose‐ dependent fashion. IL‐4 and interferon‐γ (IFN‐γ) also suppressed IgE AFC responses in a dose‐dependent fashion. However, antibodies to these cytokines had no effect. In contrast, IFN‐α increased (to fourfold) the numbers of IgE AFCs in a dose‐dependent fashion. The data are the first to show a suppressive effect of IL‐6 on human IgE responses and may also suggest a role for IL‐6 in the treatment of atopic disease.
