    Abstract:  To identify differentially expressed genes which play causal roles in pathogenesis and maintenance for psoriasis, we used BodyMapping and introduced amplified fragment length polymorphism approaches. From the BodyMap database, we selected 2007 genes which specifically expressed in epithelial tissues. Among 2007 genes, we surveyed genes which differentially expressed in involved or uninvolved psoriatic lesional skin samples compared with atopic dermatitis, mycosis fungoides, and normal skin samples. As a result of surveying 2007 genes, 241 genes were differentially expressed only in involved psoriatic skin but not in the other samples. Hierarchical cluster analysis of gene expression profiles showed that 13 independent psoriatic-involved skin samples clustered tightly together, reflecting highly similar expression profiles. Using the same 2007 gene set, we examined gene expression levels in five serial lesions from distal uninvolved psoriatic skin to involved psoriatic plaque. We identified seven genes such as alpha-1-microglobulin/bikunin precursor, calnexin, claudin 1, leucine zipper down-regulated in cancer 1, tyrosinase-related protein 1, Yes-associated protein 1, and unc-13-like protein (Coleonyx elegans) which show high-expression levels only in uninvolved psoriatic lesions. These seven genes, which were reported to be related to apoptosis or antiproliferation, might have causal roles in pathophysiology in psoriasis.

    We have investigated changes of nasal metachromatic cell number, nasal symptoms and nasal provocation at the third and sixth month during allergen immunotherapy. Twenty-five subjects with perennial allergic rhinitis (house dust (23), Alternaria (2)) were divided into two groups: an immunotherapy-treated group (n= 14) and a control group (n=11). At the first visit nasal symptom scores, nasal provocation reactions and the number of metachromatic cells in nasal mucosal epithelial scrapings were not significantly different between groups. At the third and sixth month after immunotherapy nasal symptom scores, nasal provocation and the metachromatic cells in epithelial scrapings were significantly reduced (P 〈 0.05) compared with the pretreatment values in the immunotherapy group, but unchanged in the control group. These results suggest that the reduction in metachromatic cell number at the nasal mucosal surface may be one of the mechanisms which could explain the improvement of nasal allergic symptoms by immunotherapy.

    Background The nasal mucosa is the initial site in the upper airway of host defence against antigenic challenge in the form of airborne allergens, irritants, toxins and infectious agents, and yet little is known about nasal mucosal cytokine expression and function. We hypothesized that IL-2 might play a role in immunocompetence of the upper airway.Methods IL-2 immunoreactivity was measured by ELISA in nasal secretions and by Western blot. Immunohistochemistry and electron microscopy were performed on turbinated tissue. mRNA for IL-2 was evaluated by RTPCR and Southern hybridization.Results IL-2 immunoreactivity was demonstrated by Western blot and quantitated by an enzyme immunoassay. Immunohistochemical and electron microscopy analysis of turbinate tissue revealed interstitial staining for IL-2. By RTPCR, IL-2 message was evident in 5/5 atopies and 5/5 non-atopics. IL-2 message was expressed in all subjects by Southern hybridization to an internal probe after PCR.Conclusion This study has demonstrated constitutive expression of IL-2 protein and mRNA in the upper airway of heallhy individuals. The further characterization of cytokines in the upper airway could provide useful insights into immune regulation at the mucosal level.

    Previous studies have provided the biological basis for the therapeutic use of enamel matrix derivative (EMD) at sites of periodontal regeneration. A purpose of this study is to determine effects of EMD on cell growth, osteoblastic differentiation and insulin-like growth factor-I (IGF-I) and transforming growth factor-β1 (TGF-β1) production in human periodontal ligament cells (HPLC). We also examined participation of endogenous IGF-I and TGF-β1 with EMD-stimulated cell growth in these cells. HPLCs used in this study were treated with EMD alone or in combination with antihuman IGF-I antibody (anti-hIGF-I) or anti-hTGF-β1, recombinant human bone morphogenetic protein-2 (rhBMP-2), 1,25-dihydroxyvitamin D3[1,25(OH)2D3], rhTGF-β1 or rhIGF-I. After each treatment, cell growth, the production of IGF-I and TGF-β1 and the expression of osteoblastic phenotypes were evaluated. EMD stimulated cell growth in dose-dependent and time-dependent manners. EMD was also stimulated to express IGF-I and TGF-β1 at protein and mRNA levels. The EMD-stimulated cell growth was partially suppressed by cotreatment with anti-hIGF-I or anti-hTGF-β1, and cell growth was also stimulated by treatment with rhIGF-I or rhTGF-β1. rhBMP-2 stimulated alkaline phosphatase (ALPase) activity and ALPase mRNA expression, and 1,25(OH)2D3 stimulated ALPase and osteocalcin mRNA expression. However, EMD showed no effect on the osteoblastic phenotypes expression. These results demonstrated that EMD has no appreciable effect on osteoblastic differentiation, however it stimulates cell growth and IGF-I and TGF-β1 production in HPLC, and that these endogenous growth factors partially relate to the EMD-stimulated cell growth in HPLC.
