In a recent paper, Yang and colleagues investigated the role of T cell-derived exosomes in OLP pathogenesis, finding higher IL-7, IL-10, IL-12, and IL-17 and lower IL-1β, IL-5, and IFN-γ levels within this patient category compared to healthy controls and the ability to activate keratinocytes apoptosis in vitro [78]. This evidence concerns the gene IL10 and oral lichen planus.
