I have a long-term and intensive interest in Alzheimer’s disease (AD) and some other neurodegenerative disorders. I have been working on the elucidation of p-tau conformations in the development and treatment of tauopathies.
Tau hyperphosphorylation is an early event in AD that precedes tangle formation and neurodegeneration. My ex-lab in Harvard Medical School has developed innovative antibody technology to generate conformation specific monoclonal antibodies, which allowed us to identify the very early pathogenic p-tau conformation leading to tauopathy in Traumatic Brain Injury. Using various techniques, we discovered that the monoclonal antibody not only could recognize the early pathogenic p-tau, but also is effective on blocking neurodegeneration in cell model systems and in mouse models of TBI.
My current group has focused on cistauosis in various neurological disorders as well as molecular mechanisms of neural cell death.
In particular, we are exploring tauopathy molecular mechanisms upon AD, Parkinson’s disease, Bipolar disorder, Multiple sclerosis, Diabetes Mellitus, Macular Degeneration, Spinal Cord Injury and etc. We are also interested in finding the actual reason of p-tau neurotoxicity as well as genes mediating neurodegeneration.
We are trying to design an early AD diagnosis kit. Also, we are considering antagomirs; suppressing Pin1 inhibiting miRNAs.
We have received several domestic and international grants from Alzheimer’s Association at Chicago, Brain Protein Aging Program at Nagoya, Japan and etc.
