Toxicity mechanism of Amyloid oligomer

  1. The effect on oxidative stress. Aβ can induce oxidative stress, produce a large number of free radicals, and then produce oxidative stress on neurons.
  2. Cause Ca2+ disorder. Aβ destroys the K+ channel on the cell membrane, causing a large amount of Ca2+ influx.
  3. Interaction with receptors on the cell membrane surface. Amyloid oligomers can activate excitatory NMDA2RS receptors, causing mitochondrial disorders and neuronal death.
  4. 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.
  5. Break the balance between Bax and Bel-2.
