水通道蛋白-3与皮肤研究进展

Aquaporins (AQPs) are a group of membrane transport proteins involved in the transport ofwater across cell membranes. AQP3, the most abundant aquaporin subset in human skin, is permeable notonly to water but also to small solutes such as glycerol. It has been reported that AQP3-knockout mice havereduced stratum corneum water content, elasticity and impaired wound healing. AQP3 has been revealed to berelated to cell proliferation and migration, and involved in the initiation, progression and metastasis of tumors.In addition, AQP3 expression is associated with the pathogenesis of inflammatory cutaneous diseases such asatopic dermatitis and erythema toxicum neonatorum. AQP3 expression can be modulated by multiple factorssuch as retinoic acid and tumor necrosis factor α, and this modulation may provide a new clue for the therapyof related skin diseases.     

凝血因子与荨麻疹的关系

Urticaria is a common, recurrent and refractory skin disease. The exact pathogenic mechanism of urticaria is complex and unclear. It has been proposed that the development of urticaria is associated with coagulation status. Related studies on thrombinogen fragment F (1+2), D dimmer, factor Ⅶ and factor Ⅻ revealed the activation of extrinsic pathway of coagulation cascade and signs of fibrinolysis in patients with chronic urticaria. Thromhin generation may play a key role in the pathogenesis of urticaria. And anticoagulant drugs have exhibited a good prospect in the medication of urticaria.

小鼠真皮间充质干细胞与成纤维细胞共培养对胶原分泌和TGF-β1表达的影响

Objective To explore the role of mouse dermis-derived mesenchymal stem cells (mdMSC) on skin repair. Methods mdMSC and human dermal fibroblasts were isolated and identified. Human dermal fibroblasts were cultured alone or eoeultured with mdMSC in Transwell chambers with the density ratio of human dermal fibroblasts to mdMSC being 2/5, 1/1, and 2/1. On day 4 and 8 of culture, the expression levels of hydroxyproline and transforming growth factor-beta (TGF-beta) 1 were measured in the supematant of monoculture and coculture by alkaline hydrolysis and ELISA respectively. Results The level of hydro-xyproline was significantly higher in the supematants of coculture system with a density ratio of 2/5 and 1/1 than that in monoculture supematants of human dermal fibroblasts on day 8 (both P < 0.05). Elevated level of TGF-betal was observed in all coculture supematants on day 8 (all P < 0.01) and in the supernatants of coculture system with a density ratio of 1/1 on day 4 (P < 0.05). There was no significant correlation between the expression level of TGF-betal and hydroxyproline in the coculture supernatants (r = 0.108, P ＞ 0.05). Conclusion In vitro coculture with mdMSC can increase the production of hydroxyproline and TGF-betal by fibroblasts, which may be a mechanism underlying the facilitation of skin repair by mdMSC.
