RESEARCH NEWS 2020-07-10 Research News CryoEM of frozen membranes has revealed its most intimate folds. Biochemistry of tissue extracts says it bundles up with other secretases. But how does γ-secretase, the all-important enzyme that cleaves Aβ42 from its precursor, truly behave
RESEARCH NEWS 2020-07-10 Research News Tau tracers have invigorated Alzheimer’s research, but they initially proved disappointing for other tauopathies. That is now changing, with at least two tracers, PI-2620 and APN-1607, that appear to bind specifically to the 4R tau deposits
RESEARCH NEWS 2020-07-10 Research News It’s no longer news that exercise tones the brain as well as the body, keeping cognition sharp with age and lowering the risk of Alzheimer’s disease. Exactly how this works remains murky, however. In today’s Science, researchers led by Saul
RESEARCH NEWS 2020-07-08 Research News Biogen announced today that it had submitted a biologics license application to the U.S. Food and Drug Administration for aducanumab, a therapeutic antibody developed to clear amyloid plaques from the brain. The Cambridge, Massachusetts, bio
RESEARCH NEWS 2020-07-07 Research News Synaptic connections in the brain are highly plastic, continuously forming and disconnecting to help enshrine new experiences into memories throughout life. A study published in Cell on July 1 describes a mechanism involved. Researchers led
RESEARCH NEWS 2020-07-02 Research News The blood-brain barrier keeps most plasma proteins out of the brain, but becomes leaky with age and in Alzheimer’s. Or so scientists thought. In the July 1 Nature, researchers led by Tony Wyss-Coray at Stanford University turn this idea on i
RESEARCH NEWS 2020-07-02 Research News Researchers are beginning to assess how genetic variation influences sex differences in Alzheimer’s disease. True, women who have an ApoE4 allele are more likely to develop Alzheimer’s than are male carriers, but what about the many other va
