Ted Abel, Ph.D. MIND Institute Distinguished Lecturer Series – May 18, 2016 Biographical Information Ted Abel, Ph.D., is the Brush Family Professor of Biology and Director of the Biological Basis of Behavior Program at the University of Pennsylvania where he also directs a Graduate Training Program in Behavioral and Cognitive Neuroscience. His research focuses on the molecular mechanisms of memory storage and the molecular basis of neurodevelopmental and psychiatric disorders, examining the role of signaling pathways as well as transcriptional and epigenetic regulation of gene expression. He has been a pioneer in the use of molecular and genetic approaches to define how neural circuits mediate behavior, including identifying the molecular impact of sleep deprivation on neuronal function. Dr. Abel has over 20 years of experience creating and analyzing genetically modified mouse lines to study the basis of neurodevelopmental and psychiatric disease at the behavioral, molecular, biochemical and electrophysiological level. ogy Dr. Abel was an undergraduate at Swarthmore College, receiving a B.A. in Chemistry in 1985. After Swarthmore, Dr. Abel attended the University of Cambridge (Christ’s College) as a Marshall Scholar, receiving an M. Phil. in Biochemistry and working with Dr. R. Tim Hunt on the cloning of cyclin. Dr. Abel then moved to Harvard University to work with Dr. Tom Maniatis on transcriptional regulation during Drosophila development as a National Science Foundation graduate fellow. After receiving his Ph.D. in Biochemistry and Molecular Biology in 1993 from Harvard University, Dr. Abel moved to the College of Physicians and Surgeons at Columbia University to do his postdoctoral work with Dr. Eric Kandel on genetic approaches to study the role of protein kinase A in neuronal function. During his postdoctoral research, Dr. Abel received a fellowship from the Damon RunyonWalter Winchell Cancer Research Fund and a young investigator award from the National Alliance for Research on Schizophrenia and Depression (NARSAD). In 1998, Dr. Abel joined the Biology Department at the University of Pennsylvania as an Assistant Professor. As an independent investigator, Dr. Abel has received a John Merck Scholars Award, a David and Lucile Packard Fellowship in Science and Engineering and a Research Grant from the Human Frontiers Science Program. In 1999, Dr. Abel received a Young Investigator Award from the Intellectual and Developmental Disabilities Research Center at the Children’s Hospital of Philadelphia. In 2000, he received the Daniel X. Freedman Award from NARSAD for outstanding research by a NARSAD young investigator. Dr. Abel’s accomplishments in undergraduate teaching, research and advising were recognized when he was named Biological Basis of Behavior Society Professor of the Year and selected as the recipient of the School of Arts and Sciences Dean’s Award for Mentorship of Undergraduate Research. In 2012, Dr. Abel was elected as a Fellow of the American College of Neuropsychopharmacology. Dr. Abel has co-authored over 150 scientific papers, which have been published in journals that include Nature, Science, Cell, Neuron, Journal of Clinical Investigation, Proceedings of the National Academy of Sciences and the Journal of Neuroscience. Presentation Abstract (4:30pm presentation) Male-specific deficits in mouse models of autism Neurodevelopmental disorders, including autism spectrum disorders (ASD), are highly male biased, but the underpinnings of this are unknown. Striatal dysfunction has been strongly implicated in the pathophysiology of neurodevelopmental disorders, raising the question of whether there are sex differences in how the striatum is impacted by genetic risk factors linked to neurodevelopmental disorders. We have identified male-specific deficits in striatal function important to reward learning in a mouse model of 16p11.2 hemideletion, a genetic mutation that is strongly associated with risk of neurodevelopmental disorders, particularly autism and ADHD. We find that male, but not female, 16p11.2 deletion animals show impairments in reward-directed learning and maintaining motivation to work for rewards. Male, but not female, deletion animals overexpress mRNA for dopamine receptor 2 and adenosine receptor 2a in the striatum, markers of medium spiny neurons signaling via the indirect pathway, associated with behavioral inhibition. Despite equivalent effects in males and females on the mRNA levels of genes located within the 16p11.2 region in the striatum, including the kinase ERK1, hemideletion males show increased activation in the striatum for ERK1 at baseline and in response to sucrose, a signaling change associated with decreased striatal plasticity. In contrast, we find that hemideletion females show increased protein for ERK1 as well as the related kinase ERK2, and no change in phosphorylation either at baseline or in response to sucrose. These data indicate male-specific vulnerability in the mechanisms regulating intracellular signaling in the brain as a result of a genetic lesion. Interestingly, our work indicates that other mouse models of autism also show deficits in reward learning, suggesting this as a common behavioral endophenotype of models of autism.
