Maintaining health and reducing disease-risk requires the brain to properly transduce signals across specialized regions and cell types. My lab studies neural signaling at the primary cilium, an antenna-like organelle that helps cells sense and respond to environmental cues. The function of primary cilia in the adult brain remains enigmatic. To probe cilia function, the lab will utilize mouse models, neural cultures, human brain samples, single-cell transcriptomics, proteomics, and microscopy. Ultimately, we aim to identify therapeutic targets for diseases like Alzheimer’s and Parkinson’s. |

My research interests involve investigation of proinflammatory neuroimmune and epigenetic mechanisms in animal models of developmental neurobiology and neurodegeneration, including (1) alcohol pharmacology, (2) alcohol responsivity and tolerance, (3) adolescent neurodevelopment, (4) cholinergic system and neurocircuitry, (5) microglial function, and (6) Alzheimer’s disease. A major focus of the laboratory is elucidation of neuroimmune and epigenetic mechanisms underlying adolescent binge alcohol-induced disruption of basal forebrain cholinergic neurocircuitry in adulthood. A second major focus of the laboratory is investigation of lasting adolescent binge drinking-induced neuroimmune priming as a novel etiological factor contributing to the onset and progression of basal forebrain neuropathology in Alzheimer’s disease. Our laboratory combines ex vivo and in vivo rodent models of alcohol abuse and Alzheimer’s disease with innovative molecular techniques. |

PHD PROGRAM RESEARCH INTEREST |
Our lab performs translational investigations of nutritional and microbiota determinants of host-pathogen interactions. We use gnotobiotic techniques (eg. germ free) mice to investigate complex microbe-microbe interactions in the context of host malnutrition, a common but poorly understood global health problem. Specific pathogens we model include Giardia (a ubiquitous parasite with unclear mechanisms of pathogenesis) and other intestinal parasites and multi drug resistant Enterobacterales (eg. Klebsiella). We work with several collaborators to translate findings in experimental models to outcomes in human cohorts. Emerging projects include determinants of host immune responses to mucosal viral infections and vaccines (eg. Polio and SARS-CoV-2). |

We inhale about 10,000 L of air to take oxygen into our bodies every day. Along with the inhaled air, numerous pathogens, chemical pollutants, and other irritants are inhaled, which could pose potential life-threatening risks to our lungs. However, our lungs are protected by mucociliary clearance (MCC), a critical innate defense mechanism that is important for maintaining lung health. Okuda lab’s overall research interest focuses on how the MCC system is regulated to maintain homeostasis in the lung and how it fails in muco-obstructive lung diseases, including cystic fibrosis (CF), asthma, and COPD. Our previous work successfully characterized the regional expression patterns of major airway secretory mucins, MUC5AC/MUC5B, and CFTR/ionocytes in normal and CF human airways. These investigations provide insight into the small airway region (< 2 mm in diameter) as a critical site for pathogenesis of muco-obstructive lung diseases. We have developed a microdissection technique for human small airways and established in vitro and explant small airway epithelial cell cultures. We have combined these culture systems with single-cell-based omics approaches and gene editing technologies to understand cellular biology and physiology of the human small airways. In response to the emergent situation caused by SARS-CoV-2 pandemic, Okuda lab has been also actively involved in COVID-19 research. |

Our lab aims to identify the fundamental molecular mechanisms underlying heart development and congenital heart disease. Our multifaceted approach includes primary cardiac cell culture, genetic mouse models, biochemical/molecular studies, and transcriptomics. Additionally, we employ proteomics-based methods to investigate 1) protein expression dynamics, 2) protein interaction networks, and 3) post-translational modifications (PTMs) in heart development. Current research projects focus on investigating the function of two essential PTMs in cardiogenesis: protein prenylation and palmitoylation. |

We use cutting edge technology to study pathogenesis of human pulmonary diseases including cystic fibrosis, Job’s syndrome, idiopathic pulmonary fibrosis by both human specimens, mouse genetic models, with a goal of finding the therapies. Recently, we developed a serial of lung epithelial-lineage tracing systems, providing the powerful tools for identify mechanisms of lung disease involved in post-acute sequelae SARS-CoV-2 infection, also known as “long COVID”, in collaboration with Dr. Ralph Baric’s Lab at UNC-CH. |

PHD PROGRAM RESEARCH INTEREST |
The McCauley Lab is interested in how the food we eat changes our physiology. Rare, nutrient sensing cells in the intestine called enteroendocrine cells secrete hormones in response to environmental cues that orchestrate systemic metabolism. How these cells regulate their neighbors in the gut is not well understood. We use mouse models which lack enteroendocrine cells and human pluripotent stem cell derived intestinal organoids to discover new roles for these master metabolic cells in the regulation of intestinal physiology and function. Enteroendocrine cells are dysregulated in inflammatory bowel disease, type 2 diabetes, and obesity, and loss of enteroendocrine cells results in malabsorptive diarrhea with poor survival. Our research has the potential to improve human health for a wide segment of the global population. |

PHD PROGRAM RESEARCH INTEREST |
The human placenta is the first organ to develop after fertilization and is the least studied! We hope to change this by using a multidisciplinary approach. From iPSC-derived trophoblasts in culture to mouse models and human placenta tissue, the Placental Cell Biology Group at NIEHS answers fundamental questions about placenta cell and developmental biology. Our lab uses a range of microscopy (cryo-EM, fluorescence), recombinant protein production, and -omics techniques. The goal of our research is to understand how autophagy controls placenta development, differentiation, and function. |

Our lab is interested in understanding the structural basis for activation of cell surface receptors. Using a combination of biochemistry, structural biology and cell biology, we seek to understand how the membrane environment and receptor:ligand interactions are modulated to generate the wide diversity of signaling regulated by these receptors, and how these interactions are modified in disease. |

Endothelial cells, which comprise the innermost wall of all blood vessels, are involved in a broad range of metabolic and cardiovascular diseases that represent a global challenge with high morbidity. Endothelial cell metabolism is an active process, and altered endothelial metabolism drive disease progression. The research in my lab focuses on the molecular mechanisms of endothelial cell metabolism and how they affect cardiovascular and metabolic diseases. |
