DnaK of Parvimonas micra extracellular vesicles interacts with the host fibroblasts BAG3-IKK-γ axis to accelerate TNF-α secretion in oral lichen planus

We initially revealed that P. micra was a crucial pathogen in the development of OLP and demonstrated that P. micra's EVs induce the inhibition of autophagy and enhanced TNF-α secretion in OLP fibroblasts via the DnaK-BAG3-IKK-γ axis. This study offers novel insights into the pathogenic mechanisms underlying OLP. Video Abstract.
