Our laboratory is interested in the wound response and repair of epithelium, neurons and extracellular matrix. 1. In the healthy cornea there are no blood vessels and thus the tissue provides an excellent model to study the communication between nerves and epithelium following injury. Primary neurons are co-cultured with epithelial cells to ask how signaling pathways communicate. These include but are not limited to glutamatergic and purinergic receptor-mediated calcium transients. 2. In addition to these signaling events we have found that when epithelial cells are injured nucleotides are released immediately and cause a distinct phosphorylation of EGF receptor residues that ultimately affect the ability of a cell to migrate. 3. To study controlling factors on extracellular matrix or stromal formation we have developed scaffold-free long-term cultures and these have recently enabled us to study the role of hypoxia, which occurs in a diurnal pattern in this tissue as one sleeps. Our experiments are conducted using a number of organ culture and cell models and use biochemical, cell and molecular techniques. 4. Last but not least we are interested in the role of long sugar chains or glycosaminoglycans on the formation of oligomers and fibrils in light chain amyloid disease using atomic force microscopy, negative staining and biochemical technologies.
