The National Science Foundation predoctoral fellowships are designed to help ensure the vitality of the human resource base of science and engineering in the United States and reinforces its diversity.  The program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master’s and doctoral degrees at accredited US institutions.

Unraveling Alzheimer’s: The Cohen Lab Publishes Again

September 5, 2017

The Cohen Lab just published a new article, The Deacetylase HDAC6 Mediates Endogenous Neuritic Tau Pathology in Cell Press, and the UNC School of Medicine Newsroom Interviewed Dr. Cohen on the article!  A sneak peak:

Led by Todd Cohen, PhD, assistant professor of neurology, UNC scientists used human cell cultures to show how amyloid beta can trigger a dramatic inflammatory response in immune cells and how that interaction damages neurons. Then they showed how that kind of neuron damage leads to the formation of bead-like structures filled with abnormal tau protein. Similar bead-like structures are known to form in the brain cells of people with Alzheimer’s disease.

TDP-43 in Amyotrophic Lateral Sclerosis

June 22, 2017

 TDP-43 mediated neurodegeneration in Amyotrophic Lateral Sclerosis (ALS) 

Like tau acetylation and phosphorylation in Alzheimer’s Disease, TDP-43 modifications similarly promote aberrant pathology seen in diseased brain and spinal cord of ALS and FTLD-TDP patients. Understanding such post-translational mechanisms could lead to better therapeutic avenues to pursue for ALS, FTD and other diseases characterized by TDP-43 pathology.
