Christian Lobsiger on An α2-Na/K ATPase/α-adducin complex in astrocytes triggers non-cell autonomous neurodegeneration.
COMMENT This study by Gallardo et al. from the Bonni lab is an impressive work that reveals essential new insights into the enigmatic glial-derived non-cell autonomous toxicity of ALS. The paper starts with a classic scientific approach—simple and unspectacular ...
Albrecht Clement on An α2-Na/K ATPase/α-adducin complex in astrocytes triggers non-cell autonomous neurodegeneration.
COMMENT The study by Gallardo and colleagues is certainly a significant and important contribution to the field. The authors provide compelling evidence, by cell culture and genetic studies as well as by a pharmacological treatment, that a new player in the field ...
Richard Bedlack on An α2-Na/K ATPase/α-adducin complex in astrocytes triggers non-cell autonomous neurodegeneration.
COMMENT To my knowledge, this is the first time this particular mechanism has been manipulated in any model of ALS. While this preclinical data is very interesting, it is not clear that it means anything for people with ALS yet. Many other drugs prolong survival ...
Erik Portelius on Cleavage of tau by asparagine endopeptidase mediates the neurofibrillary pathology in Alzheimer's disease.
COMMENT This is a very comprehensive study where the authors have used various techniques and models to show that a specific endopeptidase (AEP) degrades tau. It has been known for some years that tau is degraded and fragments of tau have previously been detected ...
RESEARCH NEWS 2014-10-31 Research News Neurofibrillary tangles, which contain a mixture of hyperphosphorylated tau fragments, are a hallmark of tauopathies such as Alzheimer's and frontotemporal dementia. Scientists debate which of many tau proteases contribute most to ...
