Toxic intraneuronal change
WebExperimentally, injury to central neurons begins only with anoxic depolarization. This potentially reversible, spreading wave typically starts 2-5 min after the onset of severe ischemia, marking the onset of a toxic intraneuronal change that eventually results in irreversible injury. WebOct 1, 2005 · The intraneuronal Aβ hypothesis for AD pathogenesis does not counter the established hypothesis and experimental evidence for a pathogenic role also for extracellular Aβ and/or plaques [78]. Indeed, the molecular mechanism by which extracellular Aβ can be toxic to neurons is unknown.
