Hans  Bueler was trained as a molecular biologist and neuroscientist at the  University of Zurich in Switzerland, where he received a M.S. degree in  1988 and Ph.D. in 1992. During his doctoral thesis he developed the  first prion protein (PrP)-deficient mice and showed that they were  resistant to contracting prion disease and failed to replicate the  infectious agent. This seminal finding established that PrP is essential  for prion disease pathogenesis and prion propagation. After  postdoctoral research at the Whitehead Institute for Biomedical Research  and Harvard Medical School in Boston in tumor immunotherapy, Dr. Bueler  started his own lab back at the University of Zurich as an Assistant  Professor of the Swiss National Science Foundation, focusing on the  development of viral vectors for gene therapyof Parkinson’s disease and amyotrophic laterals sclerosis. His group demonstrated that  AAV-mediated overexpression of the chaperone Hsp70 and the recessive  Parkinson’s disease-linked proteins DJ-1 and Parkin confer protection  against dopaminergic system degeneration in a mouse model of sporadic  Parkinson’s disease. As an Associate Professor at the University of  Kentucky Dr. Bueler studied the  mechanisms of neuronal dysfunction in animal models of familial  Parkinson’s disease. His lab has generated mice lacking PTEN-induced  kinase 1 (PINK1), a mitochondrial kinase linked to recessive inherited  Parkinson’s disease. PINK1 plays an important role in mitochondrial  quality control by regulating the selective degradation of depolarized  mitochondria through mitophagy. Loss of PINK1 in mice leads to  mitochondrial abnormalities, oxidative stress, alterations in  autophagy/mitophagy, defects in Akt cell survival signaling and  abnormalities in neurogenesis. These mechanisms in conjunction with  other stress factors may be involved in neurodegeneration and  neuropsychiatric disorders. Current projects in the lab investigate the  importance of PINK1 and mitochondrial function/dynamics in neural stem  biology/neurogenesis, astrocyte physiology and in the formation of  tumors.Dr. Bueler has joined the School of Life Sciences and Technology of the Harbin Institute of Technology in October 2013.
