Lu Lab's research was published in Molecular Psychiatry-Nature and was selected as a featured cover article.
Research
Dr. Lu’s research focuses on the molecular genetics and therapy of neurodegenerative and psychiatric disorders and the development of innovative neuroscience technologies. Dr. Lu completed his postdoctoral training in molecular genetics and neuroscience and was appointed as an Assistant Researcher at the Center for Neurobehavioral Genetics of the University of California, Los Angeles (UCLA). Dr. Lu developed the first BAC transgenic Parkinson’s disease (PD) mouse model that recapitulates the cardinal features of PD (licensed by Sanofi Aventis for drug discovery). His translational study of Huntington’s disease (HD) identified a novel therapeutic strategy (Science Translational Medicine, 2015; Highlighted in Nature Review Drug Discovery, and was selected as the most influential paper of 2015). Dr. Lu invented single-cell BAC transgenic technology (MORF, Mosaicism with Repeat Frameshift) that received support from the first round of the Brain Initiative award and was recently highlighted in NIH director's blog. Funded by a NARSAD Young Investigator Award, Lu lab generated the next-generation mouse model for schizophrenia (Mol Psychiatry-Nature, 2019). Lu lab recently developed a genetic sensor of DNA damage response, exploiting virus-host DNA damage response interaction (Science Advances, 2022). Lu lab also explores the future of medicine and invented a robust method for efficient and precise CRISPR/Cas9 mediated genome editing in the adult mammalian brains. Dr. Lu is funded by grants from NIEHS, NASA, and NIGMS.

RESEARCH
Mission to Mars and the Risk of Neurodegeneration (Funded by NASA 80NSSC21K0273).
 As NASA plans future exploration missions to the Martian surfaces, there is growing concern that space radiation exposure during long-term exploration missions to Mars or other destinations may initiate or accelerate the progression of cognitive decline and neurodegeneration. To use the genetic sensor to visualize space radiation induced neurodegeneration, we invented a method employing an unsupervised deep learning network to augment the quality of volume imaging in the tissue-cleared whole brains. Our studies will support Human Space Exploration by contributing the first genetic biodosimetry for quantifying brain DNA instability and neurodegenerative changes to predict clinical health outcomes in human spaceflight crews and the utility of available ground-based analogs to realize basic mechanisms that can lead to the development of biologic countermeasures. Postdocs or graduate students working on this project will have the opportunity to apply NASA fellowship and work at NASA facility at Brookhaven National Laboratory. Environmental and viral trigger of aging-dependent cognitive decline and neurodegenerative disorders (Funded by NIEHS R21ES031211-01A1 and intramural SARS-COV-2 awards)  Does the exposure to weed killer or SARS-CoV-2 infection increase our risk of developing Parkinson's disease (PD)? The majority of all PD cases have no identifiable inheritance and occur in a sporadic form. Environmental risk factors (e.g., virus infection, pesticide/herbicides, exposure to metals, solvents and polychlorinated biphenyls (PCBs), and head trauma) have been speculated as a trigger to the sporadic PD. To explore the pathogenic significance of environmental toxicant and virus exposure in sporadic neurodegenerative disorders, we designed a novel single-neuron genetic sensor. Our project also invented a small animal model with the faithful recapitulation of human ACE2 expression that is more valuable than most of the existent human ACE2 mouse models for studying pathogenesis, clinical complications, and developing exciting countermeasures for SARS-CoV-2 infection and long-haul COVID. Can immunity dictate our social behavior? A VIP link between immune dysfunction and autism (Funded by NIGMS P20GM134974-01A1).  From an evolutionary perspective, for many millions of years, human behavior, especially sociality, has been shaped by two ancient battling forces: pathogens and the immune system. Sickness behavior or avoidance of social interaction in Autism could thus be viewed as an immune input into the brain to evade the spreading of pathogens. Our study begins to quest if immune inputs can indeed affect neural circuits and behavior. This project addresses the critical questions of whether, when, and how a dysfunctional immunity can cause social deficits? Besides, whether the immune system can be therapeutically targeted to ameliorate social symptoms in autism? In this project, we will develop next generation of antipsychotic drugs using a highly potent small molecule antagonist developed in our lab in an ongoing collaboration with the National Center for Advancing Translational Sciences (NCATS) and determine its efficacy to ameliorate social deficits. Non-invasive Therapeutic Brain Genome Editing in Non-Human Primates (Collaboration with MD Anderson and Caltech)  CRISPR technology, a gene-editing tool that can be used to splice and alter the DNA inside a cell, has been hailed as the future of medicine. However, due to the complex anatomy, cell-type diversity, lack of simple, noninvasive delivery methods, and the challenge to evaluate the outcome, therapeutic genome editing in the central nervous system (CNS) has been largely limited. In order to overcome these hurdles, our lab has developed a neurotropic genome editing approach for a noninvasive, wide-scale, and dose-dependable genome editing method in adult mammalian brains. In collaboration with MD Anderson, for the first time, Lu lab is realizing brain genome editing in Non-Human Primates.
