Insights into Parkinson's balance problems

In PD, disorganized sensorimotor signals cause muscles in the limbs to contract, such that both a muscle promoting a motion and its antagonist muscle are Read more

Cajoling brain cells to dance

“Flicker” treatment is a striking non-pharmaceutical approach aimed at slowing or reversing Alzheimer’s disease. It represents a reversal of EEG: not only recording brain waves, but reaching into the brain and cajoling cells to dance. One neuroscientist commentator called the process "almost too fantastic to believe." With flashing lights and buzzing sounds, researchers think they can get immune cells in the brain to gobble up more amyloid plaques, the characteristic clumps of protein seen in Read more

Stem cell/cardiology researcher Hee Cheol Cho joins Emory

Please welcome stem cell/cardiology researcher Hee Cheol Cho to Emory. Starting in September, Cho joined the Wallace H Counter Department of Biomedical Engineering at Georgia Tech and Emory, and Emory-Children’s Pediatric Research Center. He and his team will focus on developing gene-and cell-based therapies for cardiac arrhythmias. Their research will adding to and complement the research of several groups, such as those led by Chunhui Xu, Young-sup Yoon, Mike Davis and W. Robert Taylor.

Cho comes from Cedars-Sinai Medical Center in Los Angeles, where he specialized in understanding cardiac pacemaker cells, a small group of muscle cells in the sinoatrial node of the heart that initiate cardiac contraction. These cells have specialized electrophysiological properties, and much has been learned in the last few years about the genes that control their development.

Cho and colleagues from Cedars-Sinai recently published a paper in Stem Cell Reports describing how the gene SHOX2 can nudge embryonic stem cells into becoming cardiac pacemaker cells. Read more
