Second, the two cell types found in atherosclerotic lesions that can take up cholesterol, and thus become foam cells (monocytes/macrophages and smooth muscle cells), do not accumulate cholesterol in vitro even in the presence of high concentrations of LDL. 10 Berman et al. Acetylation of LDL, originally performed with the aim of isolating the altered form of LDL that was responsible for the preceding observations, produces a modiﬁed LDL that can promote cholesterol accumulation in macrophages (95).
Atherosclerotic Plaque Development 15 D. Chemokines The recruitment of mononuclear leukocytes to the vessel wall in atherogenesis depends on the presence of both cytokines, which affect adhesion molecule expression on endothelial cells, and chemokines (chemotactic cytokines), which induce complementary integrins on leukocytes (144, 145). Chemokines have been a focus of atherosclerosis research by virtue of their ability to induce directional migration and activation of leukocytes on establishing a chemokine gradient.
Although the effects of native LDL on cultured endothelial cells appear similar to those of oxLDL, increasing evidence has shown that LDL perturbs endothelial cell function by mechanisms that differ from those attributed to oxLDL. At the level of transcription, it appears that oxLDL activates the transcription factor NF-κB, whereas LDL preferentially activates the transcription factor activator protein-1 (AP-1) (120, 121). Mechanisms of endothelial cell activation by native LDL involve calcium mobilization, activation of protein kinases, speciﬁcally JNK/SAPK, and an increase in the transcription factor c-Jun/AP-1 (122).
