immune system
abnormal macrophage physiology ( J:153833 )
• macrophages treated with excess lipoprotein-cholesterol fail to exhibit an increase in IP3-induced calcium release unlike similarly wild-type
decreased macrophage apoptosis ( J:153833 )
• under cholesterol loading conditions or after treatment with 7-ketocholesterol, macrophages treated exhibit less apoptosis compared with similarly treated wild-type macrophages

cellular
decreased sensitivity to induced cell death ( J:153833 )
• mouse embryonic fibroblasts are protected from apoptosis induced by tunicamycin or azetidine unlike wild-type cells
decreased macrophage apoptosis ( J:153833 )
• under cholesterol loading conditions or after treatment with 7-ketocholesterol, macrophages treated exhibit less apoptosis compared with similarly treated wild-type macrophages
