Studies on Nerve Fibers and Their Relationship with Langerhans Cells in the Lesional Skin of Psori-asis Vulgaris / 中华皮肤科杂志

ABSTRACT

Objectives To observe and quantify the intraepidermal and papillary dermal nerve fibers,and the contact between intraepidermal nerve fibers and Langerhans cells in the lesional skin of pso-riasis vulgaris.Methods The nerve fibers and Langerhans cells were analyzed with immunohistochemical LAB-SA method,double-labelled immunofluorescence and confocal laser scanning microscopy in28biopsies of lesional skin taken from psoriatic patients and17normal controls.Results The length of nerve fibers was significantly longer in psoriatic lesions than that in normal controls(t =4.09,P
