A suPAR circulating factor causes kidney disease

For many years, investigators have been searching for an elusive circulating factor that could cause the common kidney disease focal segmental glomerulosclerosis (FSGS). The finding that a circulating, soluble form of the urokinase receptor (suPAR) can activate podocyte β3 integrin, leading to FSGS pathology (pages 952–960), provides new insights into this disease and may have important clinical implications.
