![]() The major constituents of amyloid plaques are two abnormally folded products of APP metabolism: Aβ 40 and Aβ 42, which show a higher rate of oligomerization and insolubility.Īnother distinctive AD hallmark is represented by the presence of neurofibrillary tangles. Mutations in the amyloid precursor protein (APP) or in its processing enzyme, γ-secretase (subunit-PSEN1 (Presenilin 1) and subunit-PSEN2 (Presenilin 2)) correlates with the familial form of AD, and lead to increased β-site cleavage of APP and production of longer, aggregation-prone variants of Aβ peptides. The etiology of the disease is related to both genetic and environmental factors, making AD a cultifactorial disorder, with a major classification as late-onset AD and early-onset AD.ĪD's clinical manifestations, including memory impairment and altered cognitive functions, are caused by synaptic and neuronal loss together with a prominent inflammatory state in the entorhinal cortex, hippocampus, and neocortex (Livingston et al., 2020).ĭespite the large number of theories that attempt to explain AD-related pathomorphological changes in the brain, evidences coming from in vitro and in vivo AD models have highlighted a cytotoxic effect of amyloid β (Aβ) fragments and hyperphosphorylated TAU on neurotransmission, axonal transport, signaling cascades and immune response, leading to synaptic loss and dysfunction (Rajmohan and Reddy, 2017). According to current estimations, AD is considered the prevalent cause of dementia, accounting for 60% and 80% of cases every year.
