Although direct evidence showing the relationship between Ca2+ transport from mitochondria and lysosomes and the learning ability of patients with AD is unavailable, voltage-dependent anion channel protein 1 (VDAC1) is a hub protein that interacts with phosphorylated tau, Aβ, and γ-secretase, and it contributes to their toxic effects on triggering cell death and potentially leading to the dementia that is a characteristic of AD (Shoshan-Barmatz et al., 2018). Here, VDAC1 is linked to Alzheimer disease.
