Agent Provocateur: C9ORF72 Intron Makes Aggregating Proteins
|
 |
 DPR proteins
in disease |
Ever since scientists identified a repeat expansion in an intron of the C9ORF72 gene as the major genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD), they have puzzled over how that mutation promotes disease. In today’s Science, researchers in Germany report the surprising news that the intron expansions are translated. |
The proteins contain dipeptide repeats. They aggregate into deposits found in neurons of mutation carriers, but not in people with other types of ALS/FTLD. The discovery suggests that these dipeptide repeat proteins are major pathological players in a subset of ALS/FTLD patients. Scientists in the field hailed the findings as a major advance.

Meeting Probes Latest in AD Imaging Research and Diagnosis
|
|
 Aβ and white matter integrity |
In Miami earlier this month, at the 7th Human Amyloid Imaging conference, experts discussed the latest topics in brain imaging, from tau PET tracers to guidelines on the responsible clinical use of amyloid scans. Unexpected relationships began to emerge |
between Aβ deposition and other biomarkers, resurrecting for the moment the question of which comes first—tau or Aβ aggregation? Does cerebrospinal fluid Aβ actually dip before plaque formation? Over the coming days, read Gwyneth Dickey Zakaib's coverage of these topics and more, including the new "centiloid" project, which aims to numerically unify different Aβ tracers.

As winter stretches into its second, gloomy phase, think spring—think Italy. Register for the largest European conference on Alzheimer's and Parkinson's before current fees go up on 21 February and hotels near the conference venue are booked. Nearly 2,000 abstracts have been submitted, and thought leaders from around the world will discuss current science and research priorities with a large contingent of
young investigators, 21 of whom will receive |
awards. An imaging satellite meeting will precede the main conference on 5 March 2013. |
