Temporal proteomic analysis of BK polyomavirus infection reveals virus-induced G2 arrest and highly effective evasion of innate immune sensing

Project description:BK polyomavirus (BKPyV) is a small DNA virus that establishes a life-long persistent infection in the urinary tract of most people. BKPyV is known to cause severe morbidity in renal transplant recipients and can lead to graft rejection. The simple 5.2 kilobase pair dsDNA genome expresses just seven known proteins, thus it relies heavily on host machinery to replicate. How the host proteome changes over the course of infection is key to understanding this host:virus interplay. Here for the first time quantitative temporal viromics has been used to quantify global changes in >9,000 host proteins in two types of primary human epithelial cell throughout 72 hours of BKPyV infection. These data demonstrate the importance both of cell cycle progression and pseudo-G2 arrest in effective BKPyV replication, along with a surprising lack of innate immune response throughout the whole virus replication cycle. BKPyV thus evades pathogen recognition to prevent activation of innate immune responses in a sophisticated manner.

JC Polyomavirus Infection of Primary Human Renal Epithelial Cells Is Controlled by a Type I IFN-Induced Response

Project description:JC polyomavirus (JCPyV) established a persistent infection, but BK polyomavirus (BKPyV) killed the cells in 15 days. To identify the cellular factors responsible for controlling JCPyV infection and promoting viral persistence, we profiled the transcriptomes of JCPyV- and BKPyV-infected cells at several time points postinfection. We found that interferon-stimulated genes (ISGs) were only activated in the JCPyV and not in the BKPyV-infected cells.

Ischemia-reperfusion injury and immunosuppressants promote polyomavirus replication through common molecular mechanisms

Project description:Background Immunosuppressants and renal ischemia-reperfusion injury (IRI) are risk factors for BK polyomavirus infection after kidney transplantation. However, the mechanism remains unclear. Methods We used a model of mouse polyomavirus (MPyV) infection to investigate the mechanism of IRI and immunosuppressants to promote polyomavirus replication. Results After primary infection, MPyV established persistent infection in the kidneys until week 9 and subsequently were significantly increased by IRI or immunosuppressants treatment individually. In IRI group, viral loads peaked on day 3 in the left kidney, which were significantly higher than that in the right kidney and the control group, and then gradually decreased. In immunosuppressants group, viral loads increased on day 3 without significant difference between left and right kidney, which were significantly higher than that in the control group, and then maintained at high levels. Protein-protein interaction network analysis screened complement C3, EGFR, and FN1 as core genes. Pathway enrichment analysis based on the IRI or immunosuppressants related genes selected by WGCNA indicated that NF-?B signaling pathway was the main pathway involved in promoting MPyV replication. We further confirmed our findings using published datasets GSE47199 and GSE75693. Conclusions Our study demonstrated that IRI and immunosuppressants promote polyomavirus replication through common molecular mechanisms.
