BK polyomavirus (BKPyV or BKV) is a non‐enveloped, circular double‐stranded DNA virus that may exceed 80% seroprevalence in adults. BKV infection typically occurs during childhood, and the majority of adults are latently infected. While BKV infection is rarely associated with clinical disease in most individuals, in immunosuppressed individuals, reactivation may cause kidney (BK‐associated nephropathy) or bladder (hemorrhagic cystitis and ureteral stenosis) injury. No antiviral therapies have been approved for the treatment of BKV infection. Reducing immunosuppression is the most effective therapy, although this is not feasible in many patients. Thus, a robust understanding of viral pathogenesis and viral diversity remains important for the development of future therapeutic strategies. Studies of BKV diversity are quite sparse compared to other common viral infections; thus, much of our understanding of BVK variability and evolution relies heavily analogous studies of other viruses such as HIV or viral hepatitis. We provide a comprehensive review of BKV diversity at the population and individual level with careful consideration of how viral variability may impact viral replication, pathogenesis, tropism, and protein function. We also discuss a number of outstanding questions related to BK virus diversity that should be explored rigorously in future studies.

BK 多瘤病毒多样性 - 为什么病毒变异很重要。

BK 多瘤病毒(BKPyV 或 BKV)是一种无包膜的环状双链 DNA 病毒,在成人中的血清阳性率可能超过 80%。BKV 感染通常发生在儿童时期,大多数成年人是潜伏感染的。虽然 BKV 感染在大多数个体中很少与临床疾病相关,但在免疫抑制个体中,再激活可能导致肾脏(BK 相关肾病)或膀胱(出血性膀胱炎和输尿管狭窄)损伤。没有抗病毒疗法被批准用于治疗 BKV 感染。减少免疫抑制是最有效的治疗方法,尽管这在许多患者中并不可行。因此,对病毒发病机制和病毒多样性的深入了解对于未来治疗策略的发展仍然很重要。与其他常见病毒感染相比,对 BKV 多样性的研究非常稀少;因此,我们对 BVK 变异性和进化的理解很大程度上依赖于对其他病毒(如 HIV 或病毒性肝炎)的类似研究。我们在群体和个体层面对 BKV 多样性进行了全面审查,并仔细考虑了病毒变异性如何影响病毒复制、发病机制、趋向性和蛋白质功能。我们还讨论了一些与 BK 病毒多样性相关的悬而未决的问题,这些问题应在未来的研究中严格探讨。我们在群体和个体层面对 BKV 多样性进行了全面审查,并仔细考虑了病毒变异性如何影响病毒复制、发病机制、趋向性和蛋白质功能。我们还讨论了一些与 BK 病毒多样性相关的悬而未决的问题,这些问题应在未来的研究中严格探讨。我们在群体和个体层面对 BKV 多样性进行了全面审查,并仔细考虑了病毒变异性如何影响病毒复制、发病机制、趋向性和蛋白质功能。我们还讨论了一些与 BK 病毒多样性相关的悬而未决的问题,这些问题应在未来的研究中严格探讨。
