New evidence points to a waste-clearing problem in patients’ cells, rather than the accumulation of protein tangles, as the root cause of the neurodegenerative disease.

Damage to the lysosome, the organelle that removes excess proteins, lipids, and other materials, might be at the root of the disease.

The University of Cambridge scholar’s research on folding proteins advanced scientists’ understanding of illnesses, such as Alzheimer’s disease, Parkinson’s disease, and type 2 diabetes.

Researchers teamed up with a woman with a keen sense of smell to identify telling differences between healthy people and those with the neurodegenerative disease.

Scientists may need to seriously reconsider the cast-aside hypothesis that pathogens can play a part in diseases such as Alzheimer’s and Parkinson’s.

Clinical trials that target human endogenous retroviruses to treat multiple sclerosis, ALS, and other ailments are underway, but many questions remain about how these sequences may disrupt our biology.

This is the first time researchers have tested the use of the reprogrammed stem cells in the human brain.
