Carrion et al., using post-mortem analysis of coronary artery samples from patients with coronary artery disease and periodontal disease, showed localization of P. gingivalis-infected DCs in atherosclerotic plaques and co-localization of DCs marker, DC-SIGN, with P. gingivalis minor fimbria protein Mfa-1 (12). This evidence concerns the gene NR4A3 and coronary artery disorder.
