Abstract

Porphyromonas gingivalis may accelerate atherosclerosis progression by triggering arterial oxidative stress and inflammatory responses in mice.

  • Atherosclerotic cardiovascular diseases are linked to chronic inflammation processes.
  • Circadian clock disruption is associated with increased atherosclerosis progression.
  • Activation of the TLRs-NF-κB signaling pathway by infection may lead to enhanced oxidative stress.
  • Downregulation of a specific protein (BMAL1) could release another protein (CLOCK), which further stimulates inflammatory responses.
  • Joint administration of melatonin and metronidazole may serve as an effective treatment strategy for atherosclerotic cardiovascular diseases.
