Interleukin-9 (IL-9) has been implicated in the pathogenesis of allergic disorders. To examine the interaction between IL-9 and eosinophils, we evaluated mature peripheral blood eosinophils for their expression of the specific alpha-subunit of the IL-9 receptor (IL-9R-alpha). The expression of IL-9R-alpha by human eosinophils was detected at the messenger(More)
BACKGROUND IL-9 is a pleiotropic cytokine that exhibits biologic activity on cells of diverse hemopoietic lineage. IL-9 stimulates the proliferation of activated T cells, enhances the production of IgE from B cells, and promotes the proliferation and differentiation of mast cells and hematopoietic progenitors. OBJECTIVE In this study we evaluated the(More)
In murine models of allergic inflammation, IL-12 has been shown to decrease tissue eosinophilia, but the underlying mechanisms are not known. We evaluated the expression of IL-12R and the effect of IL-12 on eosinophil survival. In situ hybridization demonstrated the presence of mRNA and immunoreactivity for IL-12Rbeta1 and -beta2 subunits in human(More)
Interleukin-9 (IL-9) has been implicated in the pathogenesis of allergic disorders. To examine the interaction between IL-9 and eosinophils, we evaluated mature peripheral blood eosinophils for their expression of the specific ␣-subunit of the IL-9 receptor (IL-9R–␣). The expression of IL-9R–␣ by human eosinophils was detected at the messenger RNA (mRNA)(More)
Percutaneous thoracic interventions are among the most common procedures in today's medical practice. From the simple placement of a pleural drain to the ablation of lung tumors, the advent of image guidance has revolutionized minimally invasive procedures and has allowed for the introduction of new techniques and widened the range of indications. It is(More)
