Research Interests: Alzheimer’s disease and other tauopathies

Current Research: One of the fundamental questions common to all of the neurodegenerative diseases is why a particular disease targets specific neuronal populations? In early Alzheimer's disease (AD), distinct subgroups of neurons in layer II of the entorhinal cortex (EC) and the CA1 region of the hippocampus are particularly vulnerable to degeneration, while other cortical and hippocampal cell populations do not show pathological signs at this disease stage. Dr. Fu’s research focuses on understanding which subtypes of neurons are vulnerable to tau pathology in early AD and other tauopathies as well as the molecular and cellular mechanisms underlying the selective neuronal vulnerability. In particular, they are interested in investigating the role of cell-autonomous (neurons) versus cell non-autonomous (microglia and/or astrocytes) effects as well as aging in selective vulnerability to proteinopathies in neurodegenerative diseases.

In ongoing studies, they are examining: 1) which subtypes of neurons are vulnerable to tau pathology in early AD and other tauopathies; 2) why WFS1-expressing excitatory neurons are vulnerable to tau pathology in early AD; 3) what’s the role of ER stress pathways in the selective neuronal vulnerability to tau pathology; and 4) what’s the role of glial cells in the selective neuronal vulnerability to tau pathology.

The long-term goal of these studies is to identify the molecular determinants underlying the selective neuronal vulnerability of neurodegenerative diseases and to develop effective therapeutics targeting identified molecular determinants for preventing, treating and/or delaying the progression of those diseases.

Research Techniques: They take advantage of a multidisciplinary approach that combines neuropathological, neurobehavioral, confocal and light-sheet microscopy, biochemical, mouse genetic, molecular and cell biological approaches together with single cell transcriptomics and single molecule fluorescent in situ hybridization.
