Biochemical and Biological Progress in the Studies of Keratinization and Dyskeratosis
Hideoki, Ogawa,Kenji, Takamori,Makoto, Negi,Yoshiike, Takashi 대한피부과학회 1985 大韓皮膚科學會誌 Vol.23 No.4
Recent topics of biochemical and biological progress in keratinization and dyskeratosis were reviewed and discussed. The main topics were as follows: (1) what is keratin (2) Differentiation of keratinocytes (keratinization), (3) Components of horny substances and their derivation, (4) Keratin filament and keratohyaline granule, (5) Synthesis of horny cell membrane (disulfide bonds, e- (T-glutamyl) lysine bonds), (6) Biochernical analysis of dyskeratosis (harlequin fetus, ichthyosis vulgaris, X-linked ichthyosis, lamellar ichthyosis, bullous congenital ichthyosiform erythroderma, psoriasis vulgaris, Dariers disease, M:enke's syndrome, Netherton's disease, Richner-Hanhart syndrome). These findings should lead to a more cornplete understanding of the pathologic events that occur in the process of keratinization and more rational therapy for many disorders in keratinization.

Bee-collected pollen (bee pollen [BP]) has been used as a folk medicine for centuries against various diseases,including allergy. There is no study elucidating how BP exerts such an anti-allergic effect. Since mast cells play a central rolein the pathogenesis of various allergic diseases, we investigated the effect of BP on mast cell activation elicited by the Fc im-munoglobulin E (IgE) receptor (Fc.RI)-mediated pathways. The in vivo effect of orally administered BP on cutaneous mastcell activation was examined by passive cutaneous anaphylaxis reaction. In vitromast cell degranulation and IgE binding tomast cells and the status of protein tyrosine phosphorylation were examined using bone marrow-derived mast cells. Daily oraladministration of BP to mice significantly reduced the cutaneous mast cell activation elicited by IgE and specific antigens.BP also reduced in vitromast cell degranulation and tumor necrosis factor-. production by inhibiting IgE binding to Fc.RIon mast cells. The inhibitory effect of BP on mast cell degranulation by preventing IgE binding was confirmed by the re-duced levels of protein tyrosine phosphorylation, which occurred as downstream events in activated mast cells via Fc.RI.These results first revealed that the anti-allergic action of BP was exerted by inhibiting the Fc.RI-mediated activation of mastcells, which plays important roles, not only in the early phase, but also in the late phase of allergic reactions.

Background: Connective tissue growth factor (CTGF) is a multifunctional cellular protein and playing a role as a central mediator in tissue remodeling and fibrosis. The physiological function of CTGF in psoriasis is unknown. Objective: The purpose of this study was to investigate the function of CTGF in psoriasis using the established imiquimod (IMQ)- induced psoriasis murine model and psoriasis patients. Methods: Anti-CTGF monoclonal antibody was applied to IMQ induced psoriasis mice and those skin were clinically, pathologically and immunologically analyzed. Additionally, CTGF expression was analyzes using skin samples and plasma from psoriasis patients. Results: CTGF expression was observed in the dermis from both IMQ-induced psoriatic mice and psoriasis patients. CTGF inhibition using an anti-CTGF antibody slightly worsened IMQ-induced dermatitis. In addition, the increase of CTGF showed tendency to suppress the psoriatic dermatitis through inhibition of suprabasal cells proliferation and macrophage infiltration in the skin. CTGF was also detected significantly higher in plasma from psoriasis patients comparing with healthy control. Conclusion: Our findings suggest that CTGF could contribute to the healing rather than the worsening of psoriasis skin lesions. (Ann Dermatol 30(1) 47∼53, 2018)
