Studying blood vessels in the brain to develop targeted treatment for Alzheimer’s

There is more interesting research going on in the world of Alzheimer’s. Scientists are examining whether the brain’s infrastructure plays a role in a person’s risk of developing Alzheimer’s. A damaged vascular system in the brain could develop cognitive performance issues, akin to an aging power grid that struggles to deliver power to a city, according to the research discussed in this Stanford Medicine Scope blog post.

In looking at a genetic atlas of the brain, researchers found that the “majority of the top Alzheimer’s risk genes are significantly expressed in the [brain’s] vasculature.” If you want to do a deep dive into the research, take a look at the study published in Nature.

The new technology used to create a genetic atlas and the accompanying discoveries give Alzheimer’s researchers new avenues to explore. No cause and effect has been established yet between brain vascular damage and Alzheimer’s risk, but there will now be additional research conducted to examine this area.

What could this mean for potential treatment of Alzheimer’s disease down the road? According to the Tony Wyss-Coray, who runs the lab where the research was conducted, treatments that could target the brain’s vascular system may be more easily accessible as the blood-brain barrier presents a challenge when it comes to getting drugs into the brain.

New research finds potential cause of Alzheimer’s disease

A recent study from researchers at UC Riverside offers intriguing data that could lead to a better understanding of what causes Alzheimer’s disease.

Plaques and tangles in the brain have been a focus of Alzheimer’s researchers and some believe ridding the brain of the buildup will help in treating the disease. Approximately 20 percent of people have plaques detected in the brain, but do not develop dementia, prompting researchers to do a deeper investigation of the tau protein. Their results suggest that a specific presentation of the protein was linked to the development of dementia. The body has an automatic mechanism called autophagy to clear defective proteins from cells, but that process slows as we age, especially for those over the age of 65.

The researchers described the defective tau protein as “trying to put a right-handed glove on your left hand.”

If their preliminary research proves to be correct, there are drugs being tested to improve the autophagy process, which could potentially be used to treat Alzheimer’s disease.
