Even when you're older you need chaperones


The researchers are the first to find that the quality of protective genes called molecular chaperones declines dramatically in the brains of older humans, both healthy and not, and that the decline is accelerated even more in humans with neurodegenerative disease.
The researchers specifically found the decline in 100 genes, approximately one-third of all human molecular chaperone genes. Then, with additional studies, they winnowed that number down to 28 human genes specifically involved in age-associated neurodegeneration. These critical genes provide a basis for a biomarker, an early indicator of disease and a target for new therapeutics.
The study is published in the journal Cell Reports
