The new comprehensive investigation of OLP patients’ saliva cytokine expression profile performed by Zhu et al. revealed significantly increased Th1-type pro-inflammatory cytokines related to NF-κB (IL-8, IL-1β, TBF-α, IL-1α, and G-CSF), and decreased IL-13 level, indicating the Th1/Th2 cytokines imbalance and emphasizing the potential NF-κB role in OLP pathogenesis [126]. Here, CSF3 is linked to oral lichen planus.
