RESEARCH NEWS 2020-06-15 Research News The full complexity of the blood-brain barrier, with its different cell types acting together, has been difficult to model in vitro. In the June 8 Nature Medicine, researchers led by Li-Huei Tsai at the Massachusetts Institute of Technology,
RESEARCH NEWS 2020-06-12 Research News Rare variants in TREM2 and PLCG2 influence a person’s odds of developing Alzheimer’s disease, but that is far from all the two genes have in common. According to a study published June 8 in Nature Neuroscience, phospholipase C γ2 acts downst
RESEARCH NEWS 2020-06-12 Research News Just as birds of a feather flock together, genes involved in common biological pathways often soar and fall in unison, at least when it comes to their expression. If that is so, then shouldn’t a genetic variant that affects one of those co-e
RESEARCH NEWS 2020-06-12 Research News Living in an underserved neighborhood has been linked to all manner of health problems and disadvantages, and a new study adds Alzheimer’s disease to the list. In a paper published June 11 in JAMA Network Open, researchers led by Amy Kind at
RESEARCH NEWS 2020-06-06 Research News In seven papers in Nature journals published May 27, the Genome Aggregation Database (gnomAD) consortium unleashed analyses of 125,748 exomes and 15,708 whole genomes, hailing from unrelated people living on six continents across the globe.
RESEARCH NEWS 2020-06-05 Research News BACE inhibitors, with their ability to squelch Aβ production, seemed like a promising preventative therapy for Alzheimer’s disease. Unfortunately, their trials foundered, with some of them worsening cognition in an apparent class effect (Dec
RESEARCH NEWS 2020-06-05 Research News Astrocytes have been implicated in Alzheimer’s and other neurodegenerative diseases, but these beautiful, star-shaped cells are notoriously difficult to study. Animal models are little help, because their astrocytes are quite different from
RESEARCH NEWS 2020-06-02 Research News Scientists have linked loss-of-function mutations in SORL1 to overproduction of Aβ and to early onset Alzheimer’s disease. Now, in the June 2 Cell Reports, researchers led by Jessica Young at the University of Washington, Seattle, report tha
RESEARCH NEWS 2020-06-01 Research News Synapses are central in Alzheimer’s disease, but they are hard to study. The microscopic techniques that offer a glimpse at these tiny structures require expensive equipment and laborious ultra-sectioning of brain tissue, and cover only very
RESEARCH NEWS 2020-05-30 Research News Tangles creep through a person’s brain as Alzheimer’s disease progresses; alas, researchers disagree about what drives the spread of this pathology. In the May 26 Nature Communications, a collaborative group led by Alan Evans at McGill Unive
RESEARCH NEWS 2020-05-29 Research News Researchers have devised a new way to sneak therapeutic cargo across the blood-brain barrier. Into the constant region of a human IgG1 antibody, they slid a domain that latches onto receptors that carry transferrin into the brain. On the oth
RESEARCH NEWS 2020-05-28 Research News Induced pluripotent stem cell models of Alzheimer’s disease have become important because they allow researchers to study human neurons carrying AD mutations. However, iPSC lines take weeks to establish, require viral vectors to reprogram ad
RESEARCH NEWS 2020-05-27 Research News In the May 27 Nature, scientists publish the first-ever cryo-electron microscopy of α-synuclein fibrils. With resolution down to the atomic level, the analysis revealed two types of asymmetric fibril, each comprising two different protofibri
RESEARCH NEWS 2020-05-26 Research News In carriers of a pathogenic mutation in presenilin 1, plasma levels of the neurodegeneration marker neurofilament light (NfL) start to diverge from those in noncarriers more than two decades prior to when Alzheimer’s symptoms begin. That was
RESEARCH NEWS 2020-05-23 Research News RNA sequencing studies of postmortem human brain samples have generated massive datasets implicating all manner of biological functions in Alzheimer’s disease. But how do these findings translate to proteins—where the biological rubber meets
