Tau is a key protein in many neurodegenerative diseases, like Alzheimer disease, Frontotemporal dementia, traumatic brain injury, like the one the football players have, to mention some. I have established my group at the College of Staten Island, where we are interested in understanding the process of tau-induced neurodegeneration in cells, and animal models. We have generated novel animal models. We are gaining experience on live cell imaging and molecular biology. The more I learn about Tau, the more I realize that it is a very important protein in the cognitive process and in cell biology in general. We are at the verge of learning about the biology of a very interesting protein that is involved with neurodegeneration, cancer re-expression, DNA protection and mRNA regulation. Tau has been shown to be present in the nucleus, to interact with microfilaments depending on the phosphorylation. Our research will shed light on tau-biology, and will be very useful in the development of new therapeutical approaches for tauopathies. I am eager to contribute to the knowledge of Tau biology and the mechanism of Tau-Induced Neurodegeneration and at the same time, I am glad to think that I will have the opportunity to train new researchers to work in this fascinating area of research and help towards solving Alzheimer’s epidemic.
