IgG Glycosylation Causes Podocyte Injury in Transplant Glomerulopathy through Calcium Calmodulin Kinase IV
R. Bhargava, K. Maeda, M. Pavlakis, G. Tsokos
Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA
*Purpose: Transplant glomerulopathy(TG) is a major cause of late allograft loss. Increase in urine podocin/creatinine ratio in TG signifies acceleration of podocyte detachment from glomerular…
