Inhibiting Bim in all bone marrow-derived cells led to leukocytosis, reductions in plasma cholesterol and triglyceride levels, and decreased plaque apoptosis, necrotic core, and plaque sizes in ApoA1 and Ldlr double-KO mice but not in Ldlr KO mice. This evidence concerns the gene BCL2L11 and Increased total leukocyte count.
