- Blocking immune cell action increases Alzheimer's-associated protein deposits
03-27-2007 · EurekAlert!
The immune system's response against amyloid-beta, the protein that forms plaques in the brains of patients with Alzheimer's disease, appears to protect the brain from damage in early stages of the devastating neurological disorder. A report from Massachusetts General Hospital researchers finds that lack of a protein required for recruitment of the brain's primary immune cell led to increased amyloid-beta deposits and earlier death in a mouse model of Alzheimer's disease.

- When is a stem cell not really a stem cell?
08-26-2007 · EurekAlert!
Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between "true" neural stem cells and similar, but less potent versions. Their finding could simplify the isolation of stem cells not only from brain but also other body tissues.

- Brains reflect sex differences
05-10-2007 · EurekAlert!
When male primates tussle and females develop their social skills it leaves a permanent mark -- on their brains. According to research published in the online open access journal BMC Biology, brain structures have developed due to different pressures on males and females to keep up with social or competitive demands.

- Researchers find biological clock for smell in mice
12-18-2006 · EurekAlert!
Biologists at Washington University in St. Louis have discovered a large biological clock in the smelling center of mice brains and have revealed that the sense of smell for mice is stronger at night, peaking in evening hours and waning during day light hours. A team led by Erik Herzog, Ph.D., of Washington University, discovered the clock in the olfactory bulb, the brain center that aids the mouse in detecting odors.

- Penn study finds inhaled anesthetics accelerate the appearance of brain plaque in animals
03-09-2007 · EurekAlert!
Researchers at the University of Pennsylvania's School of Medicine have discovered that common inhaled anesthetics increase the number of amyloid plaques in the brains of animals, which might accelerate the onset of neurodegenerative diseases like Alzheimer's. Roderic Eckenhoff, MD, vice chair of Research in the University of Pennsylvania's Department of Anesthesia and Critical Care, and his co-authors, report their findings in the March 7 online edition of Neurobiology of Aging.

- Effects of social isolation traced to brain hormone
11-14-2007 · EurekAlert!
The anxiety and aggression that result from social isolation have been traced to altered levels of an enzyme that controls production of a brain hormone, according to a mouse study reported online in the Proceedings of the National Academy of Sciences.
