High-level polyomavirus BK (BKPyV) replication in urothelial cells is a hallmark of polyomavirus-associated hemorrhagic cystitis (PyVHC), a painful condition affecting bone marrow transplant recipients. In kidney transplant recipients, replication in tubular epithelial cells is associated with overt disease whereas high-level urothelial replication is clinically silent. We characterized BKPyV replication in primary human urothelial cells (HUCs) and compared it to replication in renal tubular epithelial cells (RPTECs). HUCs were easily infected, as shown by expression of T-antigens, VP1-3, and agnoprotein, and intranuclear virion production. Compared to RPTECs, progeny release was delayed by </=24h and reduced. BKPyV-infected HUCs rounded up like "decoy cells" and detached without necrosis as shown by delayed cytokeratin-18 release, real-time viability monitoring and imaging. The data show that BKV infection of HUCs and RPTECs is significantly different and support the notion that PyVHC pathogenesis is not solely due to BKPyV replication, but likely requires urotoxic and immunological cofactors.
