Src Induces Endothelial-to-Mesenchymal Transition and Renal Allograft Fibrosis via Promoting WNT/β-catenin Pathway
W. Zijie, Z. Gui, M. Zheng, Z. Han, J. Tao, H. Chen, L. Sun, X. Ju, R. Tan, M. Gu
Jiangsu Province Hospital, Nanjing, China
*Purpose: Endothelial-to-mesenchymal(EndMT)is recognized as an important source of myofibroblasts contributing to the pathogenesis of allograft interstitial fibrosis in our previous studies. Increased proto-oncogene tyrosine-protein kinase…

Treg-Lymphatic Interfaces: Unique Molecular Structures for Cell-Cell Interactions During Migration
C. M. Paluskievicz, W. Piao, Y. Xiong, J. S. Bromberg
U of Maryland, Baltimore, MD
*Purpose: To promote transplant tolerance, T regulatory cells (Treg) must enter the afferent lymphatic vasculature by migrating across lymphatic endothelial cells (LECs), and then home…
