BACKGROUND: ZEB1, a zinc-finger E homeobox-binding transcription factor most frequently associated with developmental programs linked to epithelial-mesenchymal transition, has been demonstrated to regulate immune cell function. The study aimed to investigate the expression pattern of ZEB1 in Th17 cells and its colocalization with p-STAT3 in human apical periodontitis lesions.
METHODS: Thirty-nine human periapical tissues were collected for ex vivo study, including periapical granulomas (PGs, n = 14), radicular cysts (RCs, n = 12), and healthy control tissues (control group, n = 13). Inflammatory infiltration of the lesions was assessed using hematoxylin-eosin staining. The expression of ZEB1 was detected and analyzed by immunohistochemistry. The localization of ZEB1 in Th17 cells and its colocalization with p-STAT3 were assessed using fluorescence colocalization.
RESULTS: ZEB1 expression was significantly higher in PGs and RCs than in the healthy control group; however no significant difference between the two groups was observed. Immunofluorescence analysis revealed that ZEB1 expression was correlated with IL17 and CD4 double-positive cells in human periapical lesions. ZEB1/ p-STAT3 double-positive cells were predominant in RCs and PGs than in the healthy control group.
CONCLUSIONS: The expression of ZEB1 was significantly elevated in PGs and RCs, and correlated with Th17 cells and p-STAT3 expression. This study revealed that ZEB1 is a potential player correlated with STAT3 activation and Th17 cells in apical periodontitis pathogenesis.
