Alterations in synaptic function have been found in transcriptomic, genetic, and proteomic studies of neurological and mental disorders. Clinical and preclinical studies suggest that synaptic dysfunction and behavioral abnormalities in disorders like Alzheimer’s disease and schizophrenia may be mechanistically linked to the emergence of imbalances between excitatory (E) and inhibitory (I) receptors. However, until recently, the electrophysiological E/I synaptic ratio had only been measured in animal models. Using pioneering methods developed in the lab, that include the reactivation and microtransplantation of synaptic receptors from frozen human brains, we have obtained electrophysiological metrics of global synaptic E/I ratios in cortical brain regions of subjects that were affected by Alzheimer’s Disease and synaptic measurements in schizophrenia. By integrating these functional metrics with large datasets across different levels of complexity (anatomical, transcriptomic, proteomic) we found that the global synaptic E/I ratio in the cortex of subjects without a psychiatric or neuro- logical diagnosis is remarkable stable in humans across postmortem intervals and brain banks; however, in addition to the synaptic loss found in AD, there are severe E/I imbalances in cortical regions associated to the behavioral abnormalities commonly found in these disorders. These analyses provide a window on the physiology of neurotransmitter receptors that were working in the human brain, and an opportunity to use this knowledge in the development of effective therapeutic strategies.

In 2016, the USC Department of Translational Genomics was created under the leadership of the founding chair John Carpten, PhD with co-leadership by Vice Chair Dr. David Craig.  The mission of USC Translational Genomics is to help the Keck School of Medicine realize its full potential in improving patient outcomes through the intentional integration of basic and clinical research.  The foundational components of our department include genome science and biomedical informatics.  The department currently includes eight faculty members dedicated to scholarship, teaching and education, and service to the community.  The department hosts several major grants and is focused on translating genomic discoveries into new knowledge that may someday have clinical application.  The department also contributes to the educational mission of the university through its master’s degree programs in Translational Biotechnology and Translational Biomedical Informatics.   Diversity is also a major component of our departmental foundation, including being among the world leaders in research studies that aim to understand the relationship between population differences and disease incidence and outcomes, and in our intentional goals for biomedical workforce diversity.
