immune system
increased macrophage apoptosis ( J:144243 )
• a higher level of intimal cell (macrophage) apoptosis is observed in atherosclerotic lesions relative to controls after receiving a Western diet for 10 weeks

cardiovascular system
cardiovascular system phenotype ( J:144243 )
N
• after 4 weeks on a Western diet, mice have similar lesion areas in proximal aortas and no or very rarely detected macrophage apoptosis in the lesions, very similar to pathology observed in controls
atherosclerotic lesions ( J:144243 )
• 8 week-old mice fed a Western diet for 4 weeks display proximal aorta lesions similar to control animals
• necrotic areas observed in lesions are larger than observed in controls after receiving a Western diet for 10 weeks
