B cells off the rails early in lupus

Emory scientists could discern that in people with SLE, signals driving expansion and activation are present at an earlier stage of B cell differentiation than previously Read more

Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

Emory basic research highlights for #AHA16

Basic research presentations at 2016 American Heart Association Scientific Sessions: cell therapy for heart attack (mesenchymal stem cells) in animal models and role of CD73, gradual release drug for atrial fibrillation, how particles from stored blood affects blood vessels.

Mesenchymal Stem Cells Require CD73 Activity to Reduce Leukocyte Associated Inflammation Following Myocardial Ischemia-Reperfusion Injury

Nov.13, 1:30 pm, Science and Technology Hall- Basic Science Theater

Cell therapy, using the patient’s own cells to reduce damage to the heart after a heart attack, has been a hot topic. Mesenchymal stem cells are derived from the bone marrow and can’t replace heart muscle. But they do exert anti-inflammatory and anti-oxidative effects, Eric Shin, MD, Rebecca Levit, MD and colleagues show in a rat model of heart attack.

The researchers use the gel material alginate to encapsulate the cells, in a way previously described by Levit. They say this is the first study to demonstrate that mesenchymal stem cells reduce reactive oxygen species production in the heart. and that the molecule CD73, which degrades ATP/ADP into adenosine, is needed for the anti-inflammatory effect. CD73 is also a cancer immunotherapy target. Read more
