The cGAS-cGAMP-STING pathway is an innate immune pathway that sensing cytosolic double-stranded DNA (dsDNA), but its role in regulating the function of PDLSCs is still unclear.. In this study, we found that mitochondrial DNA (mtDNA) was released into the cytoplasm through the mitochondrial permeability transition pore (mPTP) in PDLSCs upon inflammation, which binds to cGAS and activated the STING pathway by promoting the production of cGAMP, and ultimately impaired the osteogenic differentiation of PDLSCs.
