Interleukin-11 (IL-11), which has been detected as a stromal cell-derived cytokine, regulates multiple steps of early hematopoiesis. Synthesis of IL-11 is induced by IL-1 and transforming growth factor-beta (TGF-beta) in stromal cells and fibroblasts, but the cytokines that inhibit its production remain to be defined. In the present study, we demonstrate that interferon-alpha (INF-alpha) downregulates IL-1-induced IL-11 in human bone marrow stromal cultures. In Northern blot experiments, expression of IL-11 mRNA was reduced in the presence of INF-alpha; this inhibiton was prevented by the addition of cycloheximide. In eight independent experiments, IL-1-stimulated production of IL-11 was significantly inhibited by INF-alpha (p = 0.0117) as measured in stromal cell supernatants by specific enzyme-linked immunosorbent assay (ELISA). Dose titration experiments revealed a dose-dependent inhibition already beginning at a dose level of 10 U/mL IFN. These results are in keeping with our previous observation defining an inhibitory role of INF-alpha in the production of hematopoietic growth factors produced by the bone marrow microenvironment.
