The Role of Aβ in the Development of Alzheimer’s Disease and its Mechanisms

Alzheimer’s disease (AD) is chronic neurodegenerative dementia representing the most common cause of dementia in the elderly population. It is a major source of morbidity, mortality, and healthcare expenditure worldwide. Although the molecular and cellular properties related to AD have been demonstrated decades before the onset of clinical symptoms, AD’s pathogenesis is still unknown as a combination of risk factors causes it. Today, pathogenesis theories focused on senile plaques (SP) formed by the extracellular accumulation and deposition of Aβ peptides and neurofibrillary tangles (NFTs), which are composed of the hyperphosphorylated tau protein. Furthermore, growing evidence points out that toxic Aβ plays a primary causal role in the induction and transmission of pathology and neuronal dysfunction and loss. Therefore, Aβ is crucial to the development of AD and is a noteworthy issue in AD research. This review shows the formation of Aβ and the differences of cytotoxicity of its various isoforms and aggregation states. It also summarizes the mechanisms by which Aβ induce AD through its neurotoxicity and state how these mechanisms interact and reinforce each other.
