In ALS motor neurons, chronic ISR activation via proteostatic stress from TDP-43/FUS aggregates creates a pathological eIF2α~P state that represses axonal protein synthesis below the threshold for synaptic maintenance. In AD, we analogize that tau hyperphosphorylation and Aβ oligomerization similarly induce chronic ISR activation (via PERK/GCN2/PKR), creating eIF2α~P overflow that represses local synaptic protein synthesis required for dendritic spine maintenance and memory-related translation.
