Abstract
Early detection of BK polyomavirus (BKPyV) infection in kidney transplant recipients (KTRs) would enhance their quality of life and save the allograft. Still, many patients lose their grafted kidneys because of this infection. BKPyV microRNAs (miRNAs) have been detected in KTRs during viral infection. BKPyV produces two mature miRNAs that are named BKV-miR-B1-5p and BKV-miR-B1-3p. Additionally, BKPyV associated nephropathy (BKVAN) in kidney transplanted patients cause changes in the expression level of host genes and miRNAs such as IFN-ɣ, BCLA2A1, has-miR-10, and has-miR-30a. BKVAN can alter viral genes and miRNAs expression level, too, like viral miRNAs and T-Ag. However, their potential value as viral infection markers and the regulatory network produced by their expression during viral-host interactions needs more consideration since there are no approved medications for treating BKPyV-related diseases in KTRs. Hence, it is vital to recognize complicated facts regarding the impact of BKPyV infection on the distribution of miRNAs and mRNAs within the host cell and the virus. This article is categorized under: Translation > Regulation RNA Processing > Processing of Small RNAs RNA in Disease and Development > RNA in Disease.
