$73 million to transform big data into open-access targets and drugs for testing in clinical trials.
Hypometabolism in the frontal cortex and in the anterior default mode network distinguish the behavioral variant of AD from typical AD.
Sedentary mice infused with the plasma of active ones had more newborn neurons in the brain and less neuroinflammation. Exercising upped plasma clusterin in mice and in humans.
The G2019S variant that boosts Parkinson’s risk helps mice survive infection, but raises α-synuclein in the brain and increases neuronal death.
Spewed by stressed microglia, fragments of the organelles provoke mitochondrial fission in other cells, causing astrogliosis and neuronal loss.
In neurons derived from FTD patients, morphological changes at the base of the axon render them hyperexcitable.
In animal models and patient-derived neurons, terazosin elevated ATP and warded off neurodegeneration. Men who take the drug to control prostate hyperplasia are less likely to get PD, or have milder symptoms.
The study halted early when the primary endpoint was met, but an unusual trial design and lack of detailed data leave questions unanswered.
A chemist at the University of Cambridge, Dobson developed equations that described the kinetics of protein aggregation in diseases such as Alzheimer’s.
In induced human microglia, the E4 allele profoundly affected their health and cellular responses, while familial Alzheimer’s mutations had little effect.
Biogen and Eisai announced the discontinuation of the Phase 3 program. Elenbecestat was the only remaining BACE inhibitor being tested for AD.
The Phase 2 study missed its primary endpoint. While fewer developed dementia in the treatment group, the effect was not statistically significant. People on drug had less brain atrophy than those on placebo.
New data strengthen the idea that a healthy locus coeruleus keeps memory sharp into old age.
The organelles express unique sets of proteins depending on their environment. Astrocyte mitochondria process lipids better than those in neurons.
The pattern varied from person to person, depending on the site of injury, in contrast to the stereotyped distribution of tau tangles seen in Alzheimer’s disease.
