Salk and Stanford teams join forces to reveal two paths of neurodegeneration

...is was that "the axon degeneration at the heart of neurodegenerative diseases may be a misuse of normal pruning programs, but our studies suggest that two different mechanisms are involved." According to Luo, these findings also suggest strategies to slow neurodegeneration. "Wlds protein protects axons after injury a...

Neurons grown from embryonic stem cells restore function in paralyzed rats

... cells can protect at-risk neurons, but in ongoing neurodegenerative diseases, there is a very small window of time to do so. After that, there is nothing left to protect," says Dr. Kerr. "To overcome the loss of function, we need to actually replace lost neurons." While these results are promising, much work remains ...

The protein that makes you mad

...are proteins without DNA capable of causing rare neurodegenerative diseases, currently without a cure, by means of a novel process different from that of the "classic" virus and bacteria. The prion presents two distinct forms: a "healthy" one present in all animals (PrP c ) and another, pathogenic one (PrP sc ), whi...

...-associated protein tau is associated with several neurodegenerative diseases, and in the case of FTDP-17 (frontotemporal dementia with parkinsonism-linked to chromosome 17), tau mutations are sufficient to produce neurodegeneration. This week, Dickey et al. focused on the role of the cochaperone and ubiquitin ligase ...
