Webinar: Can Network Analysis Explain Alzheimer’s?
|
 |
 AD-specific molecular networks |
Though common genetic polymorphisms have been linked to Alzheimer's disease, scientists struggle to explain exactly how those variations influence biological function. Can network analysis help? In a complex disease such as AD, genetic and non-genetic factors conspire to disrupt biological pathways and processes. Identifying those disturbances could shed light on how risk genes cause disease. In the April 25 Cell, Valur Emilsson at the Icelandic Heart |
Association, with Eric Schadt at Mount Sinai, New York, report that they have identified molecular networks that associate with AD. Several contain known suspects, such as the microglial receptor TREM2 and the immunoglobulin-like CD33. They finger a new player, TYROBP, as a regulator of those network modules. The AD brain overproduces TYROBP and, intriguingly, it binds TREM2, and lies upstream of CD33. Lo and behold, on the same day in Neuron, researchers led by Rudy Tanzi and Ana Griciuc at Massachusetts General Hospital, Charlestown, report that microglia in the AD brain make more CD33 and that it hampers their ability to clear amyloid-β.
Join us for an Alzforum Webinar on Thursday, 23 May 2013 at 12:00 noon, U.S. Eastern time. Eric Schadt and Ana Griciuc will present their latest data and discuss them with Monica Carson, University of California, Riverside; John Hardy, University College London; and Jeremy Miller, Allen Institute for Brain Science, Seattle, Washington.

Neurodegeneration Workshop Explores New Treatment Strategies

how to move scientific discoveries from the lab bench to the clinic. Multifactorial diseases such as AD likely "cannot be conquered by a single approach or drug," said Lennart Mucke of the Gladstone Institute of Neurological Disease, San Francisco, who co-organized the meeting with Pierluigi Nicotera of the German Center for Neurodegenerative Disease. Over the coming days, read Esther Landhuis' highlights, which cover new functions for BACE, novel therapeutic approaches centered around ubiquitination, acetylation, stress response pathways, and a longevity gene.

Can Aβ in the Lens Help Diagnose Alzheimer's?
|
|
 See an AD diagnostic? |
In 2003, a research study held out the tantalizing prospect of a diagnostic test for Alzheimer's based on Aβ deposits in a type of cataract in the lens of the human eye. In the decade since, no independent replication has been published, but now scientists in Spain report that they were unable to detect Aβ in a sample of human lenses. At the same time, academic clinicians and a |
biotech company are gearing up for separate, clinical trials of Aβ-based diagnostic methods. Read Madolyn Rogers' attempt to clear up the cloudy field of Alzheimer's eye-based diagnostics. Read the full story. Image courtesy of Wikimedia Commons

Criminal Minds: Explaining Lack of Empathy in Psychopathy
|
|
 Eliciting empathy |
Ouch! Some pictures make just about anyone cringe. Not people with psychopathic tendencies, though, who experience little or no empathy for others in dire straits. A new brain imaging study helps explain why. Neurons in parts of the brain responsible for emotion fire poorly when psychopaths see someone in pain, according to the research. |
The findings, based on prisoners with psychopathy, may help scientists understand some neurodegenerative diseases. People with frontotemporal dementia often exhibit lack of empathy, and may have defects in the same brain areas. Read the full story. Image courtesy of Jean Decety, University of Chicago, Illinois
