Toxicity mechanism of Amyloid oligomer
- The effect on oxidative stress. Aβ can induce oxidative stress, produce a large number of free radicals, and then produce oxidative stress on neurons.
- Cause Ca2+ disorder. Aβ destroys the K+ channel on the cell membrane, causing a large amount of Ca2+ influx.
- Interaction with receptors on the cell membrane surface. Amyloid oligomers can activate excitatory NMDA2RS receptors, causing mitochondrial disorders and neuronal death.
- Amyloid in cells is also an important pathological feature. A large number of oligomers in the cells cause pathology. The production and degradation of Amyloid secreted by normal cells is relatively balanced.
- Break the balance between Bax and Bel-2.
