| Research Abstract |
Cigarette smoking is one of the major risks for atherosclerosis. We have identified several carbonyl compounds responsible for cell injury from cigarette main stream. These chemicals activated PKC and caused cell membrane damages and apoptosis in intracellular Ca2+-dependent manner in rat glioma C6 cells.. Furthermore, these compounds also caused intracellular Ca2+-dependent cell injury in blood vessel cells (epithelial cells and smooth muscle cells) and blood cells, and promoted differentiation of monocytes into macrophages.
