Midbrain dopaminergic neuron development
- Characterizing the molecular cascades that regulate midbrain stem cell behavior as well as dopaminergic neurogenesis, differentiation and subtype specification.
- The functions of Wnts, their receptors and their signaling pathways, with focus on new components of the Wnt/PCP signaling.
- The function of nuclear receptors and their ligands in midbrain dopaminergic neuron development.
- The identification of novel factors by single cell transcriptomic, proteomic and lipidomic approaches.
- Control of midbrain dopaminergic neurogenesis by basic-helix-loop-helix transcription factors.
Stem cells and direct reprogramming for Parkinson’s disease (PD) cell replacement therapy and drug discovery
- Improving protocols for the efficient differentiation of human stem cells (NES, ES, and iPS cells) into substantia nigra A9 dopaminergic neurons for cell replacement therapy and drug discovery.
- Develop 2D and 3D in vitro models of midbrain tissue for PD drug discovery using human NES/ES/iPS cells with PD mutations and isogenic controls.
- Examine the role of Wnt signaling in the pathogenesis of Parkinson’s disease.
- Improve protocols for the direct in vitro reprogramming of somatic cells into substantia nigra A9 dopaminergic neurons.
- Develop a novel cell replacement therapy for PD based on the direct in vivo reprogramming of striatal astrocytes in situ, into functional A9 dopaminergic neurons.
Induction of functional dopamine neurons from human astrocytes in vitro and mouse astrocytes in a Parkinson's disease model.
