Learning Impairments, Memory Deficits, and Neuropathology in Aged Tau Transgenic Mice Are Dependent on Leukotrienes Biosynthesis: Role of the cdk5 Kinase Pathway. Molecular Neurobiology, 2018; DOI: 10.1007/s12035-018-1124-7

Reversing memory deficits and impairments in spatial learning is a major goal in the field of dementia research. A lack of knowledge about cellular pathways critical to the development of dementia, however, has stood in the way of significant clinical advance. But now, researchers at the Lewis Katz School of Medicine at Temple University (LKSOM) are breaking through that barrier. They show, for the first time in an animal model, that tau pathology – the second-most important lesion in the brain in patients with Alzheimer’s disease – can be reversed by a drug.

The aorta of a mouse model of atherosclerosis on a high-fat diet for 12 months (top) has significantly more plaques (bright red) than the aorta of the same type of mouse that also produces the anti-inflammatory E06 antibody (bottom). Credit: UC San Diego Health

Researchers at University of California San Diego School of Medicine discovered that they can block inflammation in mice with a naturally occurring antibody that binds oxidized phospholipids (OxPL), molecules on cell surfaces that get modified by inflammation. Even while on a high-fat diet, the antibody protected the mice from arterial plaque formation, hardening of the arteries and liver disease, and prolonged their lives.

This study, published June 6 by Nature, marks the first demonstration in a living system that OxPL triggers in...

MIT researchers have developed technology that could be used to remotely trigger “smart pills” to deliver drugs.

New technology could enable remote control of drug delivery, sensing, and other medical applications. MIT researchers, working with scientists from Brigham and Women’s Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, monitor conditions inside the body, or treat disease by stimulating the brain with electricity or light.

The implants are powered by radio frequency waves, which can safely pass through human tissues. In tests in animals, the researchers showed that the waves can power devices located 10 centimeters deep in tissue, from a distance of 1 meter.

“Even though t...
