Our laboratory has two major research interests: hippocampus-dependent memory formation and primary cilia. “Memory is the glue that holds our mental life together” (Kandel et al., 2014). Aberrant “glue” affects our cognitive capacities and causes many cognitive dysfunction-related disorders, including dementia, amnesia, post-traumatic stress disorder (PTSD), intellectual disability, autism spectrum disorder (ASD), and major depressive disorder (MDD). Elucidating the mechanisms underlying learning, declarative memory formation and retention is needed not only to understand how we acquire and retain experiences, skills, and knowledge, but also to develop mechanism-based therapies to combat these cognitive dysfunction-related disorders. Primary cilia are centriole-derived “cellular antennae” that function to detect numerous signals ranging from photons and odorants to neurotransmitters, hormones, and morphogens, and thus regulate a variety of physiological functions including sensation, cognition, energy balance, and development. Human diseases caused by malfunctions in primary cilia include developmental disorders, polycystic kidney disease, obesity, neurodegeneration, and cognitive impairment. In the central nervous system, both neurons and astrocytes possess a single primary cilium, but their cilia exhibit a dichotomy. Primary cilia in the brain are generally under-studied, and it remains to be elucidated how neuronal primary cilia modulate neuronal function and affect learning and declarative memory formation. The first goal of my research is to determine how neuronal signal, particularly ciliary cAMP signaling, affects neuronal excitability and modulates hippocampus-dependent memory formation. The second goal is to understand how neuronal and astrocytic primary cilia sense changes in the brain and modulate neural function in health and disease conditions. My long-term vision is to build bridges between fundamental research in neuroscience and translational research, facilitating the development of novel therapies to treat cognitive dysfunction-related disorders. My vision also includes increasing efforts to train the next generation of neuroscientists and bio-technologists, and to foster the growth of pre-health sciences majors.
