Abstract
OBJECTIVES Mast cells (MCs) may play an important role in plaque destabilization and atherosclerotic coronary complications. Here, we have studied the presence of MCs in the intima and media of unstable and stable coronary lesions at different time points after myocardial infarction (MI). METHODS Coronary arteries were obtained at autopsy from patients with acute MI (up to 5 days old; n=27) and with chronic MI (5-14 days old; n=18), as well as sections from controls without cardiac disease (n=10). Herein, tryptase-positive MCs were quantified in the intima and media of both unstable and stable atherosclerotic plaques in infarct-related and non-infarct-related coronary arteries. RESULTS In the media of both acute and chronic MI patients, the number of MCs was significantly higher than in controls. This was also found when evaluating unstable and stable plaques separately. In patients with chronic MI, the number of MCs in unstable lesions was significantly higher than in stable lesions. This coincided with a significant increase in the relative number of unstable plaques in patients with chronic MI compared with control and acute MI. No differences in MC density were found between infarct-related and non-infarct-related coronary arteries in patients with MI. CONCLUSION The presence of MCs in the media of both stable and unstable atherosclerotic coronary lesions after MI suggests that MCs may be involved in the onset of MI and, on the other hand, that MI triggers intra-plaque infiltration of MCs especially in unstable plaques, possibly increasing the risk of re-infarction.

Abstract
AIM Increased clusterin mRNA and protein levels have been detected in various tissues undergoing stress, and we previously reported that clusterin is markedly induced in media and neointima following vascular injury. The present study therefore investigated the impact of clusterin on neointimal hyperplasia following vascular injury. METHODS AND RESULTS As compared with wild-type mice, clusterin knockout mice (clusterin-KO) demonstrated a significant decrease of the intima/media ratio 4 weeks after cuff placement. Immunohistochemical analysis of injured femoral arteries in clusterin-KO demonstrated the accumulation of p53 in nuclei of neointimal vascular smooth muscle cells (VSMCs). Moreover, VSMCs from either clusterin-KO or rat VSMCs treated with clusterin-short-interfering (si) RNA subjected to static stretch exhibited significantly increased p53 and p21, and increased G1 cell cycle arrest as indicated by flow cytometry compared with VSMCs from wild-type mice. CONCLUSION Reduced clusterin expression reduced the proliferation of VSMCs and induced G1 arrest via p53 and p21. Clusterin therefore represents a promising molecular target to limit restenosis after coronary intervention.
