| Popis: | Objectives: to study whether Chlamydia pneumoniae (Cpn) infection affects atherosclerotic plaque morphology in atherogenic (LDLr/ApoE −/− ) mice. Methods: in mice sacrificed 20 or 40 weeks after Cpn infection aortic arch sections were analysed for lesion and fibrous cap area and the presence of matrix metalloproteinases (MMP)-2 and -9. Results: all infected mice seroconverted, demonstrated Cpn DNA in their aortas on PCR and developed atherosclerotic plaques. Infection was not associated with changes in lesion area or type, but was associated with reduced the fibrous cap area and increased MMP-2 and -9 immunoreactivity. Conclusion: these findings suggest that Cpn infection may predispose to plaque instability. Eur J Vasc Endovasc Surg 26 , 88-95 (2003) |
