Reactive oxygen species, metalloproteinases, and plaque stability.
Understanding of the factors that lead to atherosclerotic plaque instability causing thrombosis is increasing rapidly. The morphological characteristics of plaques that are unstable, ie, complicated by recent thrombosis, lend insight into the structural and cellular features of presently stable plaques that are vulnerable, ie, at high risk of becoming unstable in the future. The risk of any ind...
متن کاملO 22: Reactive Oxygen Species and Epilepsy
Seizure activity has been proposed to result in the generation of reactive oxygen species (ROS), which then contribute to seizure-induced neuronal damage and eventually cell death. Although the mechanisms of seizure-induced ROS generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. We aim to determine the sources of seizure-induced ROS and ...
متن کاملReactive oxygen species produced by macrophage-derived foam cells regulate the activity of vascular matrix metalloproteinases in vitro. Implications for atherosclerotic plaque stability.
Vulnerable areas of atherosclerotic plaques often contain lipid-laden macrophages and display matrix metalloproteinase activity. We hypothesized that reactive oxygen species released by macrophage-derived foam cells could trigger activation of latent proforms of metalloproteinases in the vascular interstitium. We showed that in vivo generated macrophage foam cells produce superoxide, nitric oxi...

متن کاملI-3: Reactive Oxygen Species: A Dilemma for
Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
