Description of Research Expertise

I am a Children's Hospital of Philadelphia-based faculty in the Department of Psychiatry at UPenn.
The focus of my laboratory concerns the molecular and cellular mechanisms that govern the development of the mammalian forebrain. We use mouse genetics, forebrain slice and dissociated culture techniques, as well as mouse and human pluripotent stem cells in cell culture and transplantation experiments to study the fate determination of interneurons of the cerebral cortex. We are particularly interested in understanding the molecular underpinnings behind the fate determination of subclasses of GABAergic interneurons implicated in the neuropathology of autism and schizophrenia. In addition, we are using mouse and human stem cell-derived interneurons in animal models of cell-based therapies for seizures, psychosis, and as tools for the study of gene-gene and gene-environment interactions in neuropsychiatric disease.
Some Ongoing Projects:
1) Fate determination of cortical interneurons.
Example Hypothesis: Enhancement of subventricular zone-like symmetric divisions will enable the selective generation of fast-spiking, parvalbumin-expressing interneurons from mouse and human stem cells.
Translational implications. Use of stem cell derived cortical interneurons in cell based therapy for medication resistant epilepsy and psychosis.
2) Role of Mitochondria in cortical interneuron migration.
Collaborators Doug Wallace (CHOP/Penn), Jeffrey Golden (Harvard)
Hypothesis: Non-radial migration of cortical interneurons is far more dependent on oxidative phosphorylation than is radial migration of cortical projection neurons.
Translational implications. Genetic/environmental interaction in mitochondrial-related "interneuronopathies" such as epilepsy, learning disabilities, and autism-spectrum disorders, leading to novel prevention and treatment strategies.
3) Role of mitochondria dysfunction in schizophrenia.
Collaborators: Doug Wallace and Beverly Emanuel
Hypothesis. Forebrain-like excitatory projection neurons from Induced Pluriporent Stem Cells (IPSCs) from patients with schizophrenia and 22q11.2 deletion syndrome will have mitochondrial abnormalities that are correctable with antioxidants and other treatments.
Translational implications: Development of an efficient platform for drug screening, and a novel approach to understanding the complex interactions between nuclear and mitochondrial encoded genes in disorders of cortical function.
4) Role of the acetylcholine receptor AchR7 in cortical interneuron development.
Collaborator: David Lynch (CHOP/UPenn).
Hypothesis: Using Achr7 conditional mutant mice generated in the Anderson lab, we are studying the hypothesis that Achr7 signaling on fast-spiking interneurons is critical to their development of excitatory inputs via effects on serine racemase and NMDA receptor signaling.
Translational implications: Use of d-serine agonists to enhance cognition in selected subsets of people with schizophrenia.
