Porphyromonas gingivalis lipopolysaccharide regulates ephrin/Eph signalling in human periodontal ligament fibroblasts.

ABSTRACT:

Objective

EphrinA2-EphA2 and ephrinB2-EphB4 critically engage in bidirectional signalling to modulate alveolar bone remodelling. The present study aimed to investigate the effects of lipopolysaccharides (LPS) derived from Porphyromonas gingivalis on ephrin/Eph signalling in periodontal ligament fibroblasts (PDLFs).

Material and methods

The primary cultured PDLFs were incubated in the absence (as a control) or presence of P. gingivalisLPS at 0.001-10 μg/mL for 24 hours. The PDLFs were then stimulated with P. gingivalisLPS at the optimal concentration (0.1 μg/mL) for different periods (6-48 hours). The expression of ephrinA2, ephrinB2, EphA2 and EphB4 was assessed by quantitative reverse-transcription real-time polymerase chain reaction and western blotting. The osteoblastic m
