Abstract:

Periodontitis is a chronic inflammatory disease caused by bacterial infection. Epidemiological studies and in vivo/in vitro research have consistently demonstrated a strong association between periodontitis and an increased risk of cardiovascular diseases. Vascular smooth muscle cells (VSMCs) participate in the pathogenesis of atherosclerosis, aortic aneurysms, and vascular calcification via regulated cell death mechanisms (including autophagy, apoptosis, and pyroptosis) and phenotypic switching. Porphyromonas gingivalis, a critical periodontal pathogen, alters VSMC biological beha-vior, not only invading VSMCs to influence their regulated cell death process but also promoting phenotypic switching characterized by proliferation, migration, and calcification. These mechanisms play pivotal roles in cardiovascular disease development. This review aims to synthesize recent research advances and elucidate the connections between periodontitis and VSMC-regulated cell death/phenotypic switching. Novel insights into improved prevention and treatment strategies for periodontitis and cardiovascular diseases are provided.

Key words: Porphyromonas gingivalis, vascular smooth muscle cell, cardiovascular diseases, phenotypic switching, periodontitis
