Periodontal disease bacteria may kick-start Alzheimer's

Long-term exposure to periodontal disease bacteria causes inflammation and degeneration of brain neurons in mice that is similar to the effects of Alzheimer's disease in humans, according to a new study from researchers at ...

pH imbalance in brain cells may contribute to Alzheimer's disease

Johns Hopkins Medicine scientists say they have found new evidence in lab-grown mouse brain cells, called astrocytes, that one root of Alzheimer's disease may be a simple imbalance in acid-alkaline—or pH—chemistry inside ...

Antibody removes Alzheimer's plaques, in mice

Years before people start showing characteristic symptoms of Alzheimer's disease, sticky plaques begin forming in their brains, damaging nearby cells. For decades, doctors have sought ways to clear out these plaques as a ...

The brain's immune system may be key to new Alzheimer's treatments

Sanford Burnham Prebys Medical Research Institute (SBP) researchers have published two new studies in Neuron that describe how TREM2, a receptor found on immune cells in the brain, interacts with toxic amyloid beta proteins ...

Alzheimer's gene poses both risk and benefits

Scientists drilling down to the molecular roots of Alzheimer's disease have encountered a good news/bad news scenario. A major player is a gene called TREM2, mutations of which can substantially raise a person's risk of the ...
