RESEARCH NEWS 2019-09-13 Research News The humble locus coeruleus, a minute speck of tissue nestled deep in the brain stem, has received relatively scant attention in studies of cognitive decline. Now, data published September 9 in Nature Human Behavior add to a recent spate of f
RESEARCH NEWS 2019-09-14 Research News New research adds to the evidence that ApoE regulates microglial health and activity. Researchers led by Tarja Malm at the University of Eastern Finland, Kuopio, examined how several Alzheimer’s risk factors affect microglia generated from h
RESEARCH NEWS 2019-09-28 Research News In a small percentage of people with Alzheimer’s disease, behavioral changes early on—such as a disregard for social norms or loss of empathy—can lead physicians to mistakenly diagnose behavioral variant frontotemporal dementia (bvFTD). How
RESEARCH NEWS 2019-10-09 Research News Adenosine receptors may hasten inflammatory responses to tau pathology, according to a paper published this month in Brain. Researchers led by David Blum of the University of Lille, France, reported that in a mouse model of tauopathy, the ad
RESEARCH NEWS 2019-10-17 Research News ApoE4 delivers a blow to neurons in mouse models of tauopathy but, according to a paper published October 10 in the Journal of Experimental Medicine, it only does so if mice have their microglia. Researchers led by David Holtzman at Washingt
RESEARCH NEWS 2019-11-01 Research News Bucking conventional, i.e., left-leaning, wisdom for amyloid fibrils, Aβ fibrils extracted from the brains of three people with Alzheimer’s disease all twisted to the right. This is apparent in the first-ever structure of Aβ fibrils isolated
RESEARCH NEWS 2019-11-01 Research News Does ApoE4 affect aspects of Alzheimer’s disease other than amyloidosis? Animal studies have hinted as much, and now several brain imaging studies seem to agree. In a preprint posted to medRχiv on October 8, researchers led by Mark Bondi at
RESEARCH NEWS 2020-01-14 Research News As if the neurodegenerative brain didn’t have enough troubles, a study published in Nature on January 8 reports that it may be swarming with highly trained cellular henchmen. Researchers led by Tony Wyss-Coray at Stanford University found cy
RESEARCH NEWS 2020-01-23 Research News Aβ oligomers may set off tau phosphorylation by hijacking the adrenergic system, according to a study published January 15 in Science Translational Medicine. Researchers led by Qin Wang at the University of Alabama in Birmingham reported tha
RESEARCH NEWS 2020-01-24 Research News The idea that tau pathology creeps through the brain via neural circuitry may have gained its strongest support yet from a study published January 17 in Nature Communications. Drawing on longitudinal tau PET imaging data from ADNI and BIOFIN
RESEARCH NEWS 2020-02-21 Research News As the body’s most energy- and oxygen-hungry organ, the brain also happens to be the most dynamic, and it's devilishly complex. How does nutrient-rich blood wend its way through the vast labyrinth of cerebral blood vessels to nourish th
RESEARCH NEWS 2020-03-21 Research News In the March 17 Science Signaling, researchers led by Yong-Keun Jung at Seoul National University, South Korea, reported a new modulator of γ-secretase that appears to preferentially affect cleavage of amyloid precursor protein. Stress-assoc
RESEARCH NEWS 2020-04-24 Research News Proponents of LRRK2 inhibitor programs may breathe easier following a paper in the April 22 Science Translational Medicine. A collaboration led by researchers at the Michael J. Fox Foundation found that three different inhibitors of this Par
RESEARCH NEWS 2020-05-15 Research News The particular type of tangle found in Alzheimer’s is unique to this disease, making tau PET a highly specific marker. In the May 11 JAMA Neurology, researchers led by Oskar Hansson at Skåne University Hospital in Malmö, Sweden, reinforce th
RESEARCH NEWS 2020-05-15 Research News When Kevin Eggan of Harvard University decided to raise some C9ORF72-deficient mice down the road at MIT’s Broad Institute, he had little inkling of the can of worms—or microbes—that he was about to open. At Harvard, the C9-deficient mice sp
