Elodie Drapeau, PhD
- INSTRUCTOR | Psychiatry
Dr. Drapeau is an Instructor at the Department of Psychiatry and a member of the Seaver Autism Center at the Icahn School of Medicine at Mount Sinai. She received her PhD in Neurosciences and neuropharmacology at the University of Bordeaux in France in 2003 and completed a first post-doctoral training in the Laboratory of Dr. Fiona Doetsch at Columbia University, NY.
In 2009 she joined Dr. Joseph Buxbaum’s Laboratory at the Icahn School of Medicine at Mount Sinai and was promoted to the position of Instructor at the Department of Psychiatry in 2015.
Dr Drapeau's research aims to understand the mechanisms underlying the pathogenesis of neurodevelopmental and neurodegenerative disorders such as autism, schizophrenia and Alzheimer’s disease, using a multi-disciplinary approach ranging from animal models with targeted mutations to the use induced pluripotent stem cells and induced neurons from patients with autism or schizophrenia.

Dr. Drapeau research interest aims to understand the mechanisms underlying the pathogenesis of neurodevelopmental and neurodegenerative disorders such as autism, schizophrenia and Alzheimer’s disease with a long-term goal of revealing potential targets for therapeutic treatments. For this purpose, she uses a multi-disciplinary approach ranging from the characterization of animal models with targeted mutations to the use induced pluripotent stem cells and induced neurons from patients with autism or schizophrenia.
The modelling of neurodevelopmental diseases using iPSCs and neurons derived from iPSCs relies to the collection of substantial numbers of samples and appropriate controls. To this aim, Dr. Drapeau has worked in collaboration with the Conte Center for Neuroscience of Mental Disorders and the Seaver Autism Research Center to build up collections of somatic cells suitable for iPSC reprogramming.
To date, she has established primary cultures of fibroblasts for more 60 patients with schizophrenia and 60 controls and I have isolated peripheral blood mononuclear cells from more than 100 families affected by autism spectrum disorder including more than 30 families with Phelan McDermid Syndrome. From those samples, she has established several lines of iPSCs and performed in vitro differentiation of iPSC into Neuronal Precursor cells and mature glutamatergic neurons.
She also used human embryonic stem cells and iPSC to generate several genetically modified cell lines carrying genes modifications known to be involved in autism spectrum disorders using TALENs and CRISPR technology to reproduce specific rare but highly penetrant genetic variants knows or shRNA combined with medium to high throughput technologies to silence large number of candidate genes at the same time.
Additionally Dr. Drapeau has worked on the behavioral characterization of several mouse and rat models for monogenic forms of autism. Using different animal models of autism with a partial deletion of the Shank3 genes she has examined the influence of genetic background on the phenotype of the Shank3 deficient animals and has found that seizure sensitivity to pentilenetetrazol, a GABA antagonist is significantly reduced in Shank3 deficient animals while seizure sensitivity to kainic acid, a glutamatergic agonist, is not affected. In an ongoing study, she is characterizing another mouse model of Shank3 deficiency in which the Shank3 gene is fully knocked-out which leads to a more robust phenotype than the partial Shank3 knocked-out model.
Furthermore, she has established strong collaborations with several groups of various expertise that have resulted in multiple projects including participation in the Schizophrenia Working Group of the Psychiatric Genomics Consortium, the molecular validation of small exonic CNVs involved in autism spectrum disorder, the validation of PLXNA4, a gene associated with Alzheimer’s disease in post-mortem brain samples or the identification of the targets of ELAVL4, an RNA-binding protein involved in the pathology of Alzheimer’s disease in the human brain using HITS-CLIP.
