[Analysis of the phenotypic heterogeneity of CD123-positive cells in Kikuchi-Fujimoto disease using a sequential immunoperoxidase labeling and erasing method].

SIMPLE has shown the phenotypic heterogeneity of CD123-positive cells (some of them may be PDCs) and could identify 4 immunophenotypically distinct subpopulations in the affected lymph nodes in patients with KFD. Further investigations are needed to define the role of subpopulations in the pathogenesis of KFD and other diseases.
