Employer: Department of Neurology, Institute for Cell Engineering, Johns Hopkins School of Medicine
Location: Baltimore, MD21205, USA
Type: Postdoctoral Fellow
Position Overview: A postdoctoral fellow position is immediately available in the laboratory of Dr. Hanseok Ko in the NeuroRegeneration and Stem Cell Programs, Institute for Cell Engineering, Department of Neurology, Johns Hopkins University School of Medicine. There are ample opportunities to interact and collaborate with other scientist at NeuroICE (https://www.hopkinsmedicine.org/institute_cell_engineering/) and the School of Medicine.
Lab introduction: The overarching goal of our scientific work has been to define key molecular pathways in the pathogenesis of neurodegenerative diseases including PD, DLB/PDD, AD, and to identify novel targets for therapeutic development. Our lab is focused on pathways that are critical for understanding the neurodegenerative process as follows:
1. Defining the role and molecular characteristics of neuroinflammation in PD, DLB/PDD, and AD.
2. Deciphering the role of the disease-causing/risk genes in the pathogenesis in PD, DLB/PDD, and AD.
3. Mechanism that underlies gut to brain transmission of pathological α-synuclein and development of the gut-brain α-synuclein transmission mouse model.
4. The downstream neurotoxic effects of aggregated α-synuclein proteins with emphasis on oxidative stress, mitochondrial dysfunction, and the autophagic / lysosomal degradation system.
5. Mechanisms that initiate and govern the conformational conversion of soluble α-synuclein proteins into insoluble amyloid fibrils.
