郎格罕氏细胞(LC)是Paul Langerhans首先于1868年在表皮内发现的一种树突状细胞。近年来的研究认为LC具有重要的免疫功能,引起了人们极大的重视。LC主要分布于复层扁平上皮。现在还有不断的报道在更多的组织器官中发现。人们对皮肤中LC进行了大量研究,但对其它器官复层扁平上皮中LC的研究尚少,本文就近年来LC研究中的若干进展综述如下。 Langerhans cells (LC) is a dendritic cell first discovered by Paul Langerhans in the epidermis in 1868. In recent years, studies have shown that LC has important immune function, causing great attention. LC is mainly distributed in stratified squamous epithelium. There are still ongoing reports found in more tissues and organs. A great deal of research has been done on LC in the skin. However, there are few studies on LC in the stratified squamous epithelium of other organs. In this paper, some progresses in LC research in recent years are summarized as follows.
