Latest news release from McGill University, Montreal- Researchers at McGill University, lead by Drs. Alanna Watt and Anne Mckinney, have made an important step forward in understanding the cause of ARSACS. “We have shown really clearly that zebrin-negative cells in the posterior vermis were not degenerating,” Watt says. “We did not expect that. We thought eventually zebrin-negative cells in all parts of the vermis would succumb, but it’s just not what we see.” Welcome news for families affected by ARSACS. Research published in Frontiers in Cellular Neuroscience.
