Switching off brain circuit renders mice “out of touch” with environment

The sense of touch is important but often taken for granted in daily life because it seems simple and automatic. New research suggests that the apparent simplicity of tactile sensation comes from a clever two-stage brain circuit. By manipulating this circuit with light-driven optical genetic tools, researchers made laboratory mice literally “lose touch” with their surroundings as their feet became unable to sense rough or smooth surfaces.

Guidelines bring Alzheimer's blood test one step closer

A simple blood test to detect early Alzheimer's disease is a step closer to being used to screen older adults.

Detailed standardized guidelines that are needed before a blood test could be used in practice have been published in Alzheimer's & Dementia. The guidelines establish protocols and reflect the continued efforts of an international working group that includes University of North Texas Health Science Center (UNTHSC).

Proteins may slow memory loss in people with Alzheimer’s

Certain proteins may slow the devastating memory loss caused by Alzheimer's disease, according to a groundbreaking Iowa State University study.

Auriel Willette, a researcher in food science and human nutrition, found evidence that an elevated presence of a protein called neuronal pentraxin-2 may slow cognitive decline and reduce brain atrophy in people with Alzheimer's disease.

Willette will present his findings at the Psychoneuroimmunology Research Society's annual scientific meeting, June 3 to 6 in Seattle, WA, USA.
