ALTERNATE HYPOTHESIS Most researchers believe that Alzheimer’s disease is caused by amyloid plaques or protein tangles. But NPR reports that another theory has been percolating in the scientific community for decades: that the memory-ravaging illness is caused by an infectious microbe. And one advocate is putting up $1 million of his own money to anyone who can provide proof of that hypothesis. FORGET...

Researchers uncover previously unstudied cancer enzyme
UNIVERSITY OF COPENHAGEN THE FACULTY OF HEALTH AND MEDICAL SCIENCES Researchers do not know how all the proteins and enzymes in the human body function, far from it. Now researchers at the University of Copenhagen have come a bit closer to understanding how an enzyme that appears to be important to cancer development behaves inside the cells. The...

Discovery of long-lived macrophages in the intestine
New prospects in the fight against neurodegenerative conditions KU LEUVEN Macrophages are specialized immune cells that destroy bacteria and other harmful organisms. KU Leuven scientists, Belgium, have come to the surprising conclusion that some macrophages in the intestines of mice can survive for quite some time. Most importantly, these long-lived macrophages are vital for the...

Alzheimer’s one day may be predicted during eye exam
Noninvasive test may screen for disease before symptoms appear It may be possible in the future to screen patients for Alzheimer’s disease using an eye exam. Using technology similar to what is found in many eye doctors’ offices, researchers at Washington University School of Medicine in St. Louis have detected evidence suggesting Alzheimer’s in older patients who...

Scientists discover why some people with brain markers of Alzheimer’s have no dementia
A new study from The University of Texas Medical Branch at Galveston has uncovered why some people that have brain markers of Alzheimer’s never develop the classic dementia that others do. The study is now available in the Journal of Alzheimer’s Disease. PET scan of a human brain with Alzheimer’s disease. Credit: public domain Alzheimer’s disease,...

Alzheimer’s drug may stop disease if used before symptoms develop
August 1, 2018 by Fariss Samarrai, University of Virginia About 50 percent of people who reach the age of 85 will develop Alzheimer’s disease. Most will die within about five years of exhibiting the hallmark symptoms of the disease – severe memory loss and a precipitous decline in cognitive function. The reddish-blue mouse neurons in this...

Increased levels of human herpesvirus ID’d in Alzheimer’s
(HealthDay)—Subjects with Alzheimer’s disease have increased levels of two strains of human herpesvirus, according to a study published online July 11 in Neuron. Ben Readhead, M.B.B.S., from the Icahn School of Medicine at Mount Sinai in New York City, and colleagues constructed multiscale networks of the late-onset Alzheimer’s disease-associated virome, integrating genomic, transcriptomic, proteomic, and histopathological...

Newly characterized molecule offers possibilities for novel Alzheimer’s treatments
Alzheimer’s disease is an increasingly prevalent, neurodegenerative condition that erodes memory and other cognitive functions. Treatments for this complex disease have been elusive, although researchers have previously uncovered its main biological features: amyloid-beta plaques and tau tangles.
