Q1. A 60-year-old man died secondary to coronary artery disease. At the
time of autopsy marked atherosclerotic changes were present within his coro-
nary arteries. Sections from these abnormal areas revealed complicated ather-
osclerotic plaques with calcification and hemorrhage. Within these plaques
were cellular zones, composed of smooth-muscle cells and macrophages, and
a central core with foam cells and cholesterol clefts. These foam cells are
smooth-muscle cells or macrophages that have phagocytized lipid. Which
one of the following substances promotes atherosclerosis by stimulating
smooth-muscle cells to proliferate, phagocytize lipid, and excrete extracellular
matrix material?
a. Alpha-interferon
b. Beta-transforming growth factor
c. Interleukin 1
d. Platelet-derived growth factor
e. Tumor necrosis factor
