Prion infection of neurons increases the free cholesterol content in cell membranes

A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

New insight into how iron gets deposited in the brain to cause some forms of Parkinson's and Alzheimer's

Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood stream can, in certain circumstances, collapse into a state which grows long worm-like "fibrils" banded by lines of iron rust.
