Study Reveals How Collapse of Protein Processes is Driver of Aging and Death

The News in Brief:

• Scientists now have new insight to neurodegenerative diseases of aging, such as Alzheimer’s and Parkinson’s disease, based on a study that shows how the collapse of protein processes drives cell death.
• A paper in PNAS exemplifies a biophysical model of this process.
• The model details how oxidative damage and free radicals cause protein damage, accelerating cell death.

Newswise — STONY BROOK, NY, October 15, 2019 – Cells undergo natural aging and death, processes that impact a multitude of cellular factors. A new Stony Brook University-led study, to be published in PNAS, provides a biophysical model that reveals how damage accumulates in the shapes of cellular…
