BACKGROUND: Zika virus (ZIKV) infection in the human renal compartment has not
been reported. Several clinical reports have describe high-level persistent viral
shedding in the urine of infected patients, but the associated mechanisms have
not been explored until now. The current study examined cellular components of
the glomerulus of the human kidney for ZIKV infectivity. METHODS: I infected
primary human podocytes, renal glomerular endothelial cells (GECs), and mesangial
cells with ZIKV. Viral infectivity was analyzed by means of microscopy,
immunofluorescence, real-time reverse-transcription polymerase chain reaction
(RT-PCR), and quantitative RT-PCR (qRT-PCR), and the proinflammatory cytokines
interleukin 1?, interferon ?, and RANTES (regulated on activation of normal T
cells expressed and secreted) were assessed using qRT-PCR. RESULTS: I show that
glomerular podocytes, renal GECs, and mesangial cells are permissive for ZIKV
infection. ZIKV infectivity was confirmed in all 3 cell types by means of
immunofluorescence staining, RT-PCR, and qRT-PCR, and qRT-PCR analysis revealed
increased transcriptional induction of interleukin 1?, interferon ?, and RANTES
in ZIKV-infected podocytes at 72 hours, compared with renal GECs and mesangial
cells. CONCLUSIONS: The findings of this study support the notion that the
glomerulus may serve as an amplification reservoir for ZIKV in the renal
compartment. The impact of ZIKV infection in the human renal compartment is
unknown and will require further study.
