Induction of Toll‐Like Receptor Expression by <i>Porphyromonas gingivalis</i>

Abstract

This study suggests that P. gingivalis infection induces TLR2 and TLR9 upregulation in patients with CP. P. gingivalis-induced TLR2 expression in HGFs is partially dependent on TNF-α and may lead to sensitization of HGFs to bacterial components encountered in the periodontal microenvironment.
