We investigated the presence of 4 human polyomaviruses (PyVs) (WU, KI, Merkel cell, and Malawi) in respiratory specimens from a community-based birth cohort. These viruses typically were acquired when children were ≈1 year of age. We provide evidence that WU, KI, and Malawi, but not Merkel cell PyVs, might have a role in respiratory infections.

BK Polyomavirus Infection in Kidney Transplantation: A Comprehensive Review of Current Challenges and Future Directions.

Int J Mol Sci

November 2024

Kidney Transplant Department, Saint Louis Hospital, Assistance Publique-Hôpitaux de Paris, Université Paris Cité, 75010 Paris, France.

BK polyomavirus (BKPyV) infection of the kidney graft remains a major clinical issue in the field of organ transplantation. Risk factors for BKPyV-associated nephropathy (BKPyVAN) and molecular tools for determining viral DNA loads are now better defined. BKPyV DNAemia in plasma, in particular, plays a central role in diagnosing active infection and managing treatment decisions.

Chronic kidney disease is a really important heath issue, and transplantation is an intervention that can greatly increase patient quality of life and survival. The aim of this study was to perform a comprehensive evaluation of the BK virus, CMV, and EBV in kidney transplant recipients (KTRs); to assess the prevalence of infections; and to test if our detection method would be feasible for use in follow-ups with KTRs. A total of 157 KTRs registered at the Clinical Hospital "Dr.

Polyomavirus large T antigens: Unraveling a complex interactome.

Tumour Virus Res

December 2024

Department of Biological Sciences, University of Pittsburgh, Pittsburgh, PA, 15260, USA. Electronic address:

All members of the polyomavirus family encode a large T antigen (LT) protein that plays essential roles in viral DNA replication, regulation of viral gene expression, and the manipulation of numerous cellular pathways. Over 100 polyomaviruses have been discovered in hosts ranging from arthropods and fish to mammals, including fourteen that infect humans. LT is among the most studied viral proteins with thousands of articles describing its functions in viral productive infection and tumorigenesis.

BK polyomavirus (BKPyV) is a major cause of kidney transplant failure, for which there are no antivirals. The current model is that BKPyV expresses TAg (large T antigen) early during infection, promoting cells to enter S phase where the viral DNA can access the host replication machinery. Here, we performed a single-cell analysis of viral TAg expression throughout the cell cycle to reveal that robust TAg expression required replication of the host DNA first.
