Neurons in mice spit out monomeric tau when electrically stimulated, hinting that neural activity may help drive the spread of pathological forms of tau in the brain.
Superficial siderosis, a leakage of blood matter onto the outer surface of the cerebral cortex, may be linked to AD and other dementias.
A Phase 2 trial suggests that the drug PBT2 is generally safe for Huntington’s patients. The drug's sponsor says it may have improved cognition, though experts remain unconvinced.
Live imaging of the mouse brain offers a rare view of α-synuclein dynamics at presynaptic terminals, and raises questions about which form of the protein triggers synaptic dysfunction.
Proteins that interact with the Parkinson’s risk gene LRRK2 point to protein trafficking and degradation as causes of pathogenesis.
Once considered a nuclear homebody, TDP-43 ventures out to accompany mRNAs down axons to nerve terminals where the transcripts can be turned into protein.
Government, industry, and advocacy together will provide nearly $130 million for the identification of surrogate markers and targets.
It’s not just for tugging APP around the neuron: The SORLA receptor may also bind Aβ and hasten its demise.
Mutant FUS meddles with RNA splicing and DNA damage repair in transgenic mice that succumb to disease.
The antidepressant citalopram reduces agitation in Alzheimer’s patients, but caused abnormal heart rhythms at the tested dose.
Researchers have identified the striatum as a site of neurogenesis in the adult brain, but not in people with Huntington’s disease.
Aggressively treating high blood pressure and cholesterol in older adults with diabetes does not prevent cognitive decline, and results in more brain shrinkage.
A new grant opportunity will fund projects aimed at understanding the similarities and differences between biomarkers of Alzheimer’s and Parkinson’s diseases.
In a cell culture system, astrocytes from people with ALS kill motor neurons. The model could yield more discoveries about the fundamental biology of this disease.
Already linked to Alzheimer’s and other neurodegenerative diseases, a TREM2 variant now shows up on the ALS radar, too.
