UCLA scientists discover new insights that may lead to progress in fighting Alzheimer's disease

More than three decades of research on Alzheimer's disease have not produced any major treatment advances for those with the disorder, according to a UCLA expert who has studied the biochemistry of the brain and Alzheimer's for nearly 30 years.

Molecular mechanism of enterovirus infection uncovered

Researchers from the Nanoscience Center at the University of Jyväskylä in collaboration with those at the University of Helsinki have found that body proteins called albumin and certain ions within the attacked host cells can affect the genetic workings of enteroviruses and enhance their infection.

Strong free-electron lasers can be used to break down amyloid protein aggregates

Amyloid fibrils are a type of self-assembled proteins/peptides that take on a stacked sheet-like formation. Amyloid fibril aggregates are known to be a cause of several diseases--including Alzheimer's--and therefore, it is of immense scientific interest to understand how these aggregates can be broken.

Scientists unravel how cells unfold proteins

A happy cell is a balanced cell, but for every stupendously twisted protein it creates, it must tear the old ones asunder. That means untangling a convoluted pretzel-like mass for recycling. Cdc48 plays a critical role in unraveling the spent proteins.
