Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a pleiotropic cytokine whose expression is increased in numerous respiratory diseases, particularly in asthma. However, the role of GM-CSF in the pathogenesis of these conditions in vivo remains unclear. Here, we report the functional activities of GM-CSF highly expressed in rat lung after(More)
Selective accumulation of eosinophils and activated CD4+ cells is now considered a central event in the pathogenesis of asthma, and this process is thought to be mediated by a number of cytokines including tumor necrosis factor-alpha (TNF-alpha), granulocyte-macrophage colony-stimulating factor (GM-CSF), and the Type 2 cytokines interleukin-4 (IL-4) and(More)
Interleukin-10 (IL-10) is a potent anti-inflammatory/immune cytokine and has received growing attention for its therapeutic potential. To aid therapeutic studies of IL-10 in vivo, a replication-deficient adenoviral vector expressing mouse IL-10 was constructed and characterized. The transgene protein IL-10 was shown to markedly inhibit endotoxin-induced(More)
In this study, we have investigated CD40 expression in human peripheral blood eosinophils and in human chronically inflamed nasal tissues, i.e., nasal polyps. We show by both reverse transcriptase-PCR and Northern blot analysis that eosinophils from allergic subjects express human CD40 mRNA. We also show that constitutive CD40 mRNA expression in eosinophils(More)
To investigate the role of GM-CSF in asthmatic airways inflammation, we have targeted GM-CSF transgene to the airway cells in a mouse model of ovalbumin (OVA)-induced allergic airways inflammation, a model in which there is marked induction of endogenous IL-5 and IL-4 but not GM-CSF. Following intranasal delivery of a replication-deficient adenoviral gene(More)
Using adenoviral-mediated gene transfer techniques, the murine granulocyte-macrophage colony-stimulating factor (GM-CSF) transgene is efficiently targeted to and highly expressed by the respiratory epithelium of rat lung. This lung tissue-directed expression of GM-CSF induces accumulation of both eosinophils and macrophages at early stages and an(More)
The objective of this study was to investigate the contribution of the interaction between CD40 and its ligand (CD40L) to antigen-induced airways inflammatory responses. To this end, we used a model involving ovalbumin (OVA) sensitization followed by OVA aerosol challenge in CD40L knockout (KO) mice. OVA-specific IgE and IgG1 were detected in the serum of(More)
Headache in late pregnancy is warning of the presence of severe and/or lethal disorders. Here, we present a case of Vogt–Koyanagi–Harada disease (VKH), in which headache was the preceding and predominant symptom. At 37 weeks of pregnancy, a Japanese 1-para woman with an uneventful pregnancy complained of severe headache and then blurred vision. Although we(More)
The purpose of this study was to evaluate the feasibility of non-real-time CT-guided percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC, 37 lesions) untreatable by ultrasonography-guided (US)-PEIT. The HCC lesion was localized on the lipiodol CT image with a graduated grid system. We advanced a 21 G or 22 G needle in a stepwise(More)
