Daniel Barnett from the Orr Lab was awarded an NRSA F31 predoctoral fellowship from the NIA for his proposal, “Mitochondrial complex III-derived ROS in astrocytic signaling and Alzheimer’s disease-related pathogenesis”. His research will explore how complex III ROS is a context-dependent regulator of neural signaling, neuroinflammation, and proteinopathy, which may reveal complex III ROS as a novel therapeutic target for AD and related dementias.
