Pyroptosis of oral keratinocyte contributes to energy metabolic reprogramming of T cells in oral lichen planus via OPA1-mediated mitochondrial fusion.

ABSTRACT: Oral lichen planus (OLP) is a chronic inflammatory disease that is associated with an increased risk of carcinogenesis. The typical pathological features of OLP include submucosal T-cell banding, infiltration, and liquefactive degeneration of basal epithelial cells. However, the histological appearance of basal cell death cannot be explained by apoptosis of keratinocytes alone. The aim of this study was to explore a novel mechanism of epithelial cell death, pyroptosis, and its role in the development of OLP. The immunohistochemical results initially revealed pyroptosis in the epithelial cells of OLP. There was significant upregulation of pyroptosis-related inflammatory cytokines, specifically IL-1β. The expression of IL-1β is closely related to the severity of the patient's condition. In v
