The worldwide incidence, morbidity, and mortality of allergic asthma are increasing. The pathophysiological features of allergic asthma are thought to result from the aberrant expansion of CD4(+) T cells producing the type 2 cytokines interleukin-4 (IL-4) and IL-5, although a necessary role for these cytokines in allergic asthma has not been demonstrable.(More)
Two components of a receptor complex for IL-13, the IL-4R and a low affinity IL-13-binding chain, IL-13R alpha 1, have been cloned in mice and humans. An additional high affinity binding chain for IL-13, IL-13R alpha 2, has been described in humans. We isolated a cDNA from the thymus that encodes the murine orthologue of the human IL-13R alpha 2. The(More)
Schistosoma mansoni egg-induced pulmonary granuloma formation is a cell-mediated inflammatory response associated with dominant Th2-type cytokine expression, tissue eosinophilia, and high levels of serum IgE. In the present study, we show that in vivo blockade of the Th2 cytokine IL-13, using soluble IL-13R alpha2-Fc fusion protein, significantly reduced(More)
The effects of recombinant human interleukin-11 (rhIL-11) on in vivo mouse megakaryocytopoeisis were examined. Normal C57Bl/6 mice and splenectomized C57Bl/6 mice were treated for 7 days with 150 micrograms/kg rhIL-11 administered subcutaneously. In normal mice, peripheral platelet counts were elevated compared with vehicle-treated controls after 3 days of(More)
We have investigated the mechanism of action of the thrombopoietic cytokine, recombinant human interleukin-11 (rhIL-11), on megakaryocytopoiesis in vitro. We have shown that rhIL-11-induced murine and human megakaryocytopoiesis are not mediated by thrombopoietin (Tpo). Murine megakaryocytes (MKs) were produced from bone marrow (BM) mononuclear cells(More)
We have examined the effects of recombinant human interleukin-11 (rhIL-11) on the recovery of peripheral blood cell counts and proliferation of progenitors and hematopoietic stem cells (day 12 colony-forming units-spleen-CFU-S12) in vivo using a mouse bone marrow (BM) and spleen cell transplantation model. Recovery of leukocytes was accelerated in animals(More)
Previous studies have shown that subcutaneous (SC) bolus administration of recombinant human interleukin-11 (rhIL-11) stimulates megakaryocytopoiesis and increases peripheral platelet counts in naive mice. This study was designed to determine whether administration of rhIL-11 by constant SC infusion altered either the magnitude of the nature of the(More)
Behavior in social groups follows unwritten codes, with the social group one is embedded in defining what behavior is acceptable and what is not. Prior research has found strong tendencies toward informational isomorphism in groups in online social networks, as social peers seem to establish a shared understanding of what behavior is acceptable and what(More)
Lethally irradiated mice were transplanted with syngeneic bone marrow cells infected with a recombinant retrovirus vector containing the human interleukin-11 (hIL-11) cDNA under the control of the human cytomegalovirus (CMV) immediate early promoter. The hIL-11 RNA transcript from the vector was detected in the spleen and bone marrow of the recipient mice,(More)
