A defective skin epidermal permeability barrier (EPB) is responsible for a high mortality rate in premature infants and is an important risk factor in inflammatory skin diseases such as eczema. We report here fast and accurate methods for measurement of EPB in animal models or in human patients using simple techniques that monitor diffusion of dyes (X-Gal or Lucifer Yellow) through the upper epidermis and measure transepidermal water loss (TEWL) resulting from a defective skin barrier. Accurate diagnosis and early detection of EPB defects in human patients are critical for effective treatment of certain classes of inflammatory skin diseases.
有缺陷的皮肤表皮渗透屏障(EPB)是导致早产儿高死亡率的原因,也是湿疹等炎症性皮肤病的重要风险因素。我们在此报告了在动物模型或人类患者中测量EPB的快速准确方法,这些方法使用简单技术监测染料(X-Gal或荧光素黄)透过表皮上层的扩散,并测量因皮肤屏障缺陷导致的经表皮水分流失(TEWL)。准确诊断和早期发现人类患者的EPB缺陷对于有效治疗某些类型的炎症性皮肤病至关重要。
