RESUMO
Human cytomegalovirus (HCMV) is a major renal pathogen in congenitally infected infants and renal allograft recipients. We postulated that a specific renal cell type was involved in HCMV infection and reactivation. Human fetal kidney cortex cell cultures were assayed for their ability to support HCMV infection. Infectious center assays indicated that the low level of viral replication observed by virus yield assay occurred from a fraction of the cells in the mixed cultures. Virus-specific immunofluorescence and in situ hybridization documented the presence of HCMV-specific protein and nucleic acid, respectively, in a morphologically distinct cell type. These cells were purified, were identified as kidney mesangial cells, and were observed to support efficient HCMV replication. Our research identifies mesangial cells as a renal cell type that supports HCMV replication and provides evidence to implicate these cells in the pathogenesis of HCMV-induced renal disease.
