Brain organoid model shows molecular signs of Alzheimer’s before birth

In a model of human fetal brain development, Emory researchers can see perturbations of epigenetic markers in cells derived from people with familial early-onset Alzheimer’s disease, which takes decades to appear. This suggests that in people who inherit mutations linked to early-onset Alzheimer’s, it would be possible to detect molecular changes in their brains before birth. The results were published in the journal Cell Reports. “The beauty of using organoids is that they allow us to Read more

Make ‘em fight: redirecting neutrophils in CF

Why do people with cystic fibrosis (CF) have such trouble with lung infections? The conventional view is that people with CF are at greater risk for lung infections because thick, sticky mucus builds up in their lungs, allowing bacteria to thrive. CF is caused by a mutation that affects the composition of the mucus. Rabindra Tirouvanziam, an immunologist at Emory, says a better question is: what type of cell is supposed to be fighting the Read more

Targeting metastasis through metabolism

Research from Adam Marcus’ and Mala Shanmugam’s labs was published Tuesday in Nature Communications – months after we wrote an article for Winship Cancer Institute’s magazine about it. So here it is again!

At your last visit to the dentist, you may have been given a mouth rinse with the antiseptic chlorhexidine. Available over the counter, chlorhexidine is also washed over the skin to prepare someone for surgery. Winship researchers are now looking at chlorhexidine and its chemical relative alexidine for another purpose: stopping cancer metastasis.

While the researchers don’t envision using chlorhexidine mouthwash as an anti-cancer measure directly, their findings suggest ways to combine other drugs, already in clinical trials, in ways that could deplete the cells needed for metastasis.

When used as an antiseptic, chlorhexidine is basically a detergent that blasts bacteria apart, scientists think. As leads for potential anti-cancer agents, chlorhexidine and its relatives appear to have a different effect. They interfere with mitochondria, the miniature power plants in our cells. Cancer cells trying to metastasize and invade other tissues seem to need their mitochondria more—especially the cells that are leading the way. Read more
