lymphatic signatures, imaging Our work focuses on developing new imaging methodologies and applying these methodologies to improve our understanding of human tissue function in health and disease. A major emphasis of our work is to utilize vascular blood and lymphatic signatures to identify subtle changes in physiology that precede overt symptoms and clinical disease manifestations, and as such can be used to triage patients for disease-modifying therapies prior to irreversible tissue damage. Applications of this work by lab investigators and our immediate collaborators focus on cerebrovascular disease and stroke, HIV, peripheral lymphatic disorders, anemia, fat disorders, and neurodegeneration.

I study angiopoiet tie2 signaling pathway in the development and function of the lymphatic system.

We are broadly interested in cellular and molecular mechanisms governing angiogenesis and lymphangiogenesis. Our research has revealed Neuropilin2 and Semaphorin3A as novel regulators of lymphangiogenesis (Development 2002, J Cell Biol 2010, Circ Res 2012). We have also found that lymphatic endothelial button junctions in the small intestine control chylomicron uptake, and that zippering (closing) such junctions can prevent chylomicron uptake, thereby rendering mice resistant to diet-induced obesity (Science 2018). Our current research aims at understanding molecular mechanisms controlling development of lymphatic endothelial junctions, with the long-term goal to develop novel treatments to prevent dietary fat uptake and combat obesity.

We also study the role lymphatic vessels play in a variety of disease settings, including lymphedema, bacterial infections, obesity and sequelae of aging. Finally, we study the role of lymphatic vessels in cancer progression, including how cancer cells growing in lymph nodes can spread further in the body and disrupt anti-tumor immune responses. To accomplish these goals, we have innovated a variety of intravital microscopy tools to allow us to longitudinally follow lymphatic function over the development of a disease process or in response to therapy.

We employ a unique combination of physiological and genetic approaches to answer these questions, including knockout and transgenic models.
