Many neurodegenerative diseases involve oxidative stress and excitotoxic cell death. In an attempt to further elucidate the signal transduction pathways involved in the cell death/cell survival associated with excitotoxicity, we have used an in vivo model of excitotoxicity employing kainic acid (KA)-induced neurotoxicity. Here, we show that extracellular signal-related kinase (ERK) 2, but not ERK...
Oxidative stress is involved in several neurodegenerative diseases including Alzheimer's disease, Parkinson's disease and ischemic reperfusion injury (stroke). We have established clones of the murine hippocampal neuronal cell line HT22, which are resistant to the oxidative stress-causing agents glutamate and hydrogen peroxide, respectively. These cell clones show a mutual cross-resistance to other...
