Lipopolysaccharides and hydrogen peroxide induce contrasting pathological conditions in dental pulpal cells

Lipopolysaccharides and hydrogen peroxide induce contrasting pathological conditions in dental pulpal cells

To determine the effects of lipopolysaccharides (LPS), hydrogen peroxide (H2O2), and both combined on cell proliferation/differentiation, inflammation, mitochondrial dynamics as indicated by mitochondrial fission/fusion, antioxidants as indicated by superoxide dismutase 2 (SOD2), and apoptosis of human dental pulpal cells (HDPCs). These findings suggest that LPS induced inflammation, imbalanced mitochondrial dynamics, and reduced cell differentiation without altering apoptosis and cell proliferation. However, H2O2 decreased cell proliferation and differentiation and increased inflammation and apoptosis without interfering with mitochondrial dynamics. Based on the findings, combining LPS and H2O2 could be potentially used as the inducers in vitro study to mimic the clinical pulpitis.
