Professional Affiliations & Contributions
My research?interest is broadly on understanding of cellular mechanism of gradual pathology progression in neurodegenerative diseases. Additionally, we work on characterizations of transient aggregates in Alzheimer’s and Parkinson’s diseases and their relevance in oxidative cellular stress (Nath et al. Biophysical J. 2010; Nath et al. Mol. Cell.?Neurosc. 2010 and Goodwin et al. Neurochem Int. 2013). ?Our research works have indicated that spreading of pathology in Alzheimer’s disease is due to direct cell-to-cell transfer of amyloidogenic oligomers and lysosomal stress/accumulations enhance its progression ((Domert et al.?Neurobiol?Dis. 2014; Nath et al. J.?Neurosci. 2012; Hallbeck et al. Neuroscientist. 2013). We are also interested in lysosomal stress and membrane leakage in Parkinson’s model (Nath & Eriksson et.al. Eur J Cell Biol, 2017). Microscopic observations of direct-cell-to-cell transfer of oligomers also indicated formation of tunnelling nanotube structures.
