We previously reported that decreasing levels of brain‐derived neurotrophic factor (BDNF) promoted beta‐amyloid (Aβ)‐induced neuronal cell death in neuron‐like differentiated SH‐SY5Y (ndSH‐SY5Y) human neuroblastoma cells in an AD mimic cell model. This evidence concerns the gene BDNF and Alzheimer disease.
