This proposal requests 5 years of additional funding for the UCLA Intellectual and Developmental Disabilities Research Center (IDDRC). For over 40 years, our mission has been to provide an optimal environment for conducting multidisciplinary research into the mechanisms underlying intellectual and developmental disabilities (IDDs), to translate these findings into effective treatments for IDDs, and disseminate these findings to the scientific community and the public. This submission expands on the translational focus that we began 5 years ago with an added emphasis on human research and clinical trials, and closer ties to the community. Each of the 5 cores are structured to facilitate interdisciplinary collaborations, following four thematic goals: 1) providing state of the art infrastructure for IDD related research; 2) encourage innovation by supporting technical development and providing financial incentives for new projects; 3) promote integration across disciplines, by encouraging interdisciplinary research among faculty and between cores; and 4) to disseminate advances in technology to other scientists, train new IDD investigators, and convey findings to the scientific community and stakeholders in community outreach efforts. We propose 5 interacting cores: A: Administration and Dissemination, which oversees core functions and usage, assures quality and accountability, and promotes outreach and dissemination; B: Clinical Translation, supporting clinical trials, recruitment, diagnosis and deep phenotyping, and biosample collection; C: Genetics, Genomics and BioInformatics, which performs genetic analysis, sequencing, expression, and provides resources for planning and executing analysis of genomics data; D: Cells, Circuits and Systems, supporting human iPSC and 3-dimensional organoid development, in- and ex- vivo electrophysiology and optogenetics; and E: Structural and Functional Visualization, which provides training, access, and analysis services for in vitro microscopy, mini-cameras for in vivo visualization, animal and human structural and functional MRI and spectroscopy. Our model research project focuses on mechanisms underlying sleep impairments in two IDDs, building on new findings from our last submission: a near absence of slow-wave sleep in Dup15q syndrome. We will examine mechanisms underlying sleep impairments in Dup15q and Rett's Syndrome using a multidisciplinary approach that includes a clinical component, animal models, and brain organoid model using patient-derived IPSCs, to elucidate how mechanisms underlying altered sleep physiology lead to cognitive dysfunction. Results from this project will directly inform next steps for developing interventions that may modulate sleep and, in turn, neurodevelopment in IDDs.

Public Health Relevance

For over 40 years, the UCLA IDDRC has committed to improving the lives of individuals with intellectual and developmental disabilities (IDDs) through basic and translational research, education, and outreach. Our center aims to provide outstanding resources and infrastructure to UCLA researchers focused on IDDs using the most innovative technologies that will significantly impact the well-being of individuals with IDDs and their families. This application requests 5 years of funding to support our Core infrastructure and a novel multidisciplinary project that examines the origins of abnormal sleep physiology and cognition. A new dissemination program extends our reach into the community to enhance inclusiveness and two-way communication with the public and stakeholders.
