    Liver Kinase B1 Knockdown Induces Platelet-Derived Growth Factor Receptor B Expression in Human Airway Epithelial Cells: A Potential Mechanism for Development of Fibrosis Leading to Chronic Lung Allograft Dysfunction

    M. Rahman, J. Lee, R. Ravichandran, T. Fleming, M. Smith, R. Bremner, T. Mohanakumar

    St. Joseph’s Hospital and Medical Center, Phoenix, AZ

    *Purpose: The platelet-derived growth factor and its receptor (PDGFRb) signaling pathway can be activated by epithelial mesenchymal transition which facilitates fibrosis. It is not known…

    Non-Invasive Measurement of Transplant Kidney Fibrosis Using Photoacoustic Imaging

    E. Hysi1, X. He1, A. Krizova1, M. Ordon1, K. T. Pace1, M. Farcas1, M. C. Kolios2, D. A. Yuen1

    1St. Michael's Hospital, Toronto, ON, Canada, 2Ryerson University, Toronto, ON, Canada

    *Purpose: The presence of donor kidney fibrosis adversely impacts transplant outcome. Biopsy remains the only method that can assess fibrosis, despite being subjected to sampling…
