The emergence of humans: the coevolution of intelligence and longevity with intergenerational transfers.

abstract：:The human chaperonin Hsp60 is thought to play a role in the progression of Alzheimer's disease by mitigating against intracellular β-amyloid stress. Here, we show that the bacterial homolog GroEL (51% sequence identity) reduces the neurotoxic effects of amyloid-β(1-42) (Aβ42) on human neural stem cell-derived neuronal...
