Triple play in science communication

We are highlighting Emory BCDB graduate student Emma D’Agostino, who is a rare triple play in the realm of science communication. Emma has her own blog, where she talks about what it’s like to have cystic fibrosis. Recent posts have discussed the science of the disease and how she makes complicated treatment decisions together with her doctors. She’s an advisor to the Cystic Fibrosis Foundation on patient safety, communicating research and including the CF community Read more

Deep brain stimulation for narcolepsy: proof of concept in mouse model

Emory neurosurgeon Jon Willie and colleagues recently published a paper on deep brain stimulation in a mouse model of narcolepsy with cataplexy. Nobody has ever tried treating narcolepsy in humans with deep brain stimulation (DBS), and the approach is still at the “proof of concept” stage, Willie says. People with the “classic” type 1 form of narcolepsy have persistent daytime sleepiness and disrupted nighttime sleep, along with cataplexy (a loss of muscle tone in response Read more

In current vaccine research, adjuvants are no secret

Visionary immunologist Charlie Janeway was known for calling adjuvants – vaccine additives that enhance the immune response – a “dirty little secret.” Janeway’s point was that foreign antigens, by themselves, were unable to stimulate the components of the adaptive immune system (T and B cells) without signals from the innate immune system. Adjuvants facilitate that help. By now, adjuvants are hardly a secret, looking at some of the research that has been coming out of Emory Read more

Promising probe for detecting recurrent prostate cancer

Part of the new Winship magazine feature on prostate cancer focuses on a PET imaging probe called FACBC, which was developed by radiologists at Emory. 18F-FACBC (anti-1-amino-3-[18F]fluorocyclobutane-1-carboxylic acid, also called “fluciclovine”) has a lengthening track record in detecting recurrent prostate cancer.

Structure of FACBC, from patent application.

Usually in PET imaging, radioactive glucose is injected into the body, and since cancer cells have a sweet tooth, they take up a lot of the radioactive tracer. But plenty of the tracer also appears in the urine, complicating prostate cancer detection efforts, since the prostate is so close to the bladder. In contrast, FACBC is readily taken up by prostate cancer cells, but doesn’t appear as much in urine.

Because of space considerations, we did not include David Schuster’s description of how FACBC’s utility in prostate was first discovered. Several years ago, he and Mark Goodman had begun investigating the probe’s potential in imaging brain tumors and kidney tumors, and used it with a patient with a large renal mass and many enlarged lymph nodes, as described in the radiology newsletter Aunt Minnie.
