Autism Research

Autism Research lectures bring together scientists and scholars to discuss diverse and important topics related to autism. The lectures are open to the public and are held at the Gerald D. Fischbach Auditorium at the Simons Foundation headquarters in New York City. Tea is served prior to each lecture.

On 23 April, Gail Mandel presented the complex pathology of Rett syndrome and discussed whether this autism-related disorder would be amenable to gene replacement strategies.

Her talk was part of the Simons Foundation Autism Research lecture series. You can watch a complete video recording of the event above.
 

About the Lecture

A central goal in neuroscience is determining the genetic basis of neurological disorders — from autism to brain tumors. Many of these pathological states result from defects in gene regulatory programs that are fundamental to all cell types but lead to dysfunction specifically within the nervous system. Mandel investigates the basis of this phenomenon and has identified cell-cell interactions between neurons and glia — brain cells that support neurons and help process information — involved in brain development.

Mandel has been able to treat the brain pathology of one autism-related disorder, Rett syndrome, by genetically replacing the defective MeCP2 gene with a good copy of the gene in astrocytes — a type of glia. She is exploring the underlying mechanisms crucial for neuronal signaling.

About the Speaker

Gail Mandel holds a Ph.D. in immunology from the University of California, Los Angeles, and did postdoctoral work in biochemistry and molecular biology there and at the University of California, San Diego, and Harvard Medical School. She began her career at Tufts Medical School, where she was one of the first investigators to clone and express mammalian voltage-dependent ion channels. In the department of neurobiology and behavior at Stony Brook University, she identified the protein REST, which is responsible for regulation of sodium channel expression and the acquisition of cellular excitability. These discoveries have helped unlock the mechanisms through which embryonic cell types differentiate specifically into neurons. Mandel is a senior scientist in the Vollum Institute at Oregon Health & Science University. She is an Investigator of the Howard Hughes Medical Institute and a member of the American Academy of Sciences and the National Academy of Sciences.

Altered somatosensory processing in autism spectrum disorders: Mechanisms and emerging therapeutic opportunities

David Ginty, Ph.D.Professor of Neurobiology, Harvard University

On April 24, 2019, David Ginty presented his work on the neurobiological basis of touch over-reactivity in mouse models of autism spectrum disorder (ASD). He also discussed new pharmacological approaches aimed at reducing sensory over-reactivity and potentially improving cognitive and behavioral abnormalities associated with ASD.
