Polyomavirus-Specific Cellular Immunity: From BK-Virus-Specific Cellular Immunity to BK-Virus-Associated Nephropathy?
In renal transplantation, BK-virus (BKV)-associated nephropathy has emerged as a major complication, with a prevalence of 1-10% and graft loss in >50% of cases. BKV is a member of the polyomavirus family and rarely induces apparent clinical disease in the general population. However, replication of polyomaviruses, associated with significant organ disease, is observed in patients with acquired ...
متن کاملPolyomavirus BK-specific immunity after kidney transplantation.
Failure to mount or maintain a protective immune response may influence the development of polyomavirus BK (BKV)-associated nephropathy (PVAN). However, limited data are so far available on BKV-specific immunity after kidney transplantation. BKV-specific cellular immune response was retrospectively analyzed in kidney recipients with or without BKV infection/reactivation by measuring the frequen...
متن کامل[BK-virus-associated Nephropathy].
The infection by the BK Polyomavirus (BKV) is an emerging problem in kidney transplants that contributes to a chronic loss of kidney grafts, and in which immunosuppression plays a decisive role. Understanding its risk factors and strictly monitoring urine and serological markers of the infection could mitigate the undesirable effects of this disease. In this review, we investigate the clinical ...
متن کاملQuantitation of BK Virus DNA for Diagnosis of BK Virus-Associated Nephropathy in Renal Transplant Recipients
Quantitative measurement of BK virus DNA (Q-BKDNA) has been used for the early diagnosis and monitoring of BK virus-associated nephropathy (BKVAN). This study was designed to determine the BKDNA cutoff for the diagnosis of BKVAN. Between June 2005 and February 2007, 64 renal transplant recipients taken renal biopsies due to renal impairment submitted plasma and urine for Q-BKDNA. Eight BKVAN pa...
متن کاملInterplay of cellular and humoral immune responses against BK virus in kidney transplant recipients with polyomavirus nephropathy.
Reactivation of the polyomavirus BK (BKV) causes polyomavirus nephropathy (PVN) in kidney transplant (KTx) recipients and may lead to loss of the renal allograft. We have identified two HLA-A*0201-restricted nine-amino-acid cytotoxic T lymphocyte (CTL) epitopes of the BKV major capsid protein VP1, VP1(p44), and VP1(p108). Using tetramer staining assays, we showed that these epitopes were recogn...
