Objectives: Impairment of cell-mediated immunity in cervical cancer (CC) and intraepithelial neoplasia (CIN) has been reported. In this study, Langerhans cells (LC) subpopulations were quantitatively evaluated in cervical tissuesamples obtained from Brazilian patients exhibiting progressive grades of CIN, (CIN)I (n=3), CINII (n=3) and CINIII (n=3), in addition to three normal controls.
Methods: The precise number of cervical LC was determined in the entire area of lesioned epithelium from CIN samples, by performing a morphometric analysis of Langerhans cells positive for two distinct markers, S100 and Langerin (Lang) detected either by Immunofluorescence or Immunohistochemistry analysis.
Results: In normal cervix, a higher density of Langerin+ cells was observed whereas S100+ LC were predominant in pre-neop.. View More»
