TIMP2 and acute kidney injury: Fig 2B at the upper panel represents the course of patient#1. This patient is also depicted in Fig 2B lower panel for TIMP-2 staining. 19 patients showed casts under which 14 were transplant recipients. Leukocyturia was found in 35 patients; among them 26 were transplant recipients. Analysis of protein expression in urinary sediment using TIMP-2-specific immunostaining was performed in fourteen representative patients (Fig 2B lower panel representing patient#1) upon admission, during and after recovery from AKI.
