Dimitri Krainc - Founder

Job Titles:
  • Co - Founder
  • Scientific Advisor
  • Chairman, Department of Neurology, and Director, Simpson Querrey Center for Neurogenetics at Northwestern University, Feinberg School of Medicine / Chair of the Vanqua Bio Scientific Advisory Board

Previously, he spent over two decades at Massachusetts General Hospital and Harvard Medical School where he completed his research and clinical training and served on the neurology faculty. His group discovered how to improve degradation of aggregation-prone proteins such as mutant huntingtin and a-synuclein by the lysosomal pathway. They identified a positive feedback loop between alpha-synuclein and lysosomal glucocerebrosidase in synucleinopathies (Cell, 2011). Using patient-specific neurons, his lab discovered a link between mitochondrial and lysosomal dysfunction in neurodegeneration of human but not mouse midbrain neurons (Science, 2017). Based on these findings, Dr. Krainc's group initiated the development of activators of lysosomal glucocerebrosidase as targeted therapeutics for Parkinson's disease. Their recent discovery of direct contacts between mitochondria and lysosomes and organelle dynamics has implications for various neurological and other disorders (Nature, 2108).
