氧化应激
Increased levels of oxidative stress can be caused in part by neuroinflammation, which is a highly recognized part of cerebral ischemia as well as many neurodegenerative diseases including Parkinson's disease, Alzheimer's disease, and amyotrophic lateral sclerosis. The increased levels of oxidative stress are widely targeted in neuroprotective treatments because of their role in causing neuron apoptosis. Oxidative stress can directly cause neuron cell death or it can trigger a cascade of events that leads to protein misfolding, proteasomal malfunction, mitochondrial dysfunction, or glial cell activation. If one of these events is triggered, further neurodegradation is caused as each of these events causes neuron cell apoptosis. By decreasing oxidative stress through neuroprotective treatments, further neurodegradation can be inhibited.
