Abstract

Human keratinocytes were investigated for the presence of single cilia. Almost all basal keratinocytes were found to carry a single cilium in normal, occluded, and psoriatic skin. The ciliary structure was progressively reduced in keratinocytes approaching the surface. No remnants of the ciliary apparatus were found in the granular layer. In one case of nickel-allergic dermatitis (patch test), the keratinocytes had lost their cilia; the significance of this surprising finding remains to be elucidated.

摘要

对人类角质形成细胞是否存在单纤毛进行了研究。在正常皮肤、闭塞皮肤和银屑病皮肤中，几乎所有基底角质形成细胞都发现有一根单纤毛。接近皮肤表面的角质形成细胞中，纤毛结构逐渐减少。颗粒层未发现纤毛器的残余物。在一例镍过敏性皮炎（斑贴试验）中，角质形成细胞失去了纤毛；这一惊人发现的意义尚待阐明。
