Research Interests

To investigate the modulation of the permeability of small blood vessels we measure the permeability properties of the intact endothelial barrier in individual microvessels (15-40microns in diameter) in living tissue, using microperfusion techniques. Current projects involve investigation of the role of sphingosine -1-phosphate in the regulation of endothelial cell adhesion and contractile mechanisms, the transition from a normal anti-inflammatory to a more pro-inflammatory endothelial cell phenotype in microvessels after exposure to inflammatory conditions, and the role of atrial natriuretic peptide in anti-inflammatory mechanisms (Supported by N.I.H. HL-28607 1982-2015). We have also developed a combined biophysical, bio-engineering, ultrastructural and microperfusion approach to investigate the role of the endothelial glycocalyx as a barrier to water and macromolecule transport, and as a mechanotransducer in the maintenance of normal permeability and increases in small solute (nutrient) permeability. These studies link investigations of mechanisms which regulate vascular permeability at the cellular and molecular level with investigations of the functional properties of water and solute exchange in intact tissue and whole organs. We have active collaborations with investigators at the University of Bergen, Norway to develop new MR Imaging methods to measure vascular permeability in the tissue of transgenic mouse models of modified vascular permeability (e.g. in Epac KO mouse); with investigators at City College, New York to investigate the stability of the endothelial and with colleagues at UC Davis Biomedical Engineering to investigate macromolecule delivery in tumors, and wound healing using advanced multimodal imaging techniques (Micro PET and long wavelength fluorescence scanning).
