Activation of <scp>RANKL</scp>‐induced osteoclasts and memory T lymphocytes by <i>Porphyromonas gingivalis</i> is serotype dependant

Abstract

P. gingivalis serotypes K1 and K2, but not others, are associated with an increased production of the osteoclastogenesis-related factor RANKL. This important information suggests that these serotypes could elicit a greater bone resorption in vivo and have a role in the periodontitis pathogenesis.
