Dr. Creighton's research focuses on the discovery of endogenous repair mechanisms situated in the lung’s vascular lining, the endothelium. Her current projects include: the function of Adenosine Monophosphate-activated Protein Kinase (AMPK) with respect to sub-cellular localization and tissue specific expression. Areas of interest related to this central theme include: metabolic mechanisms controlling endothelial permeability; endothelial cell-cell adhesion: cadherin expression and adherens junction composition; calcium channel regulation by vascular protective mechanisms; and endothelial phenotype specific response to stimuli.
