    摘要: The disclosure relates to methods and reagents for analyzing samples for the presence of JC virus antibodies. Disclosed is a method that includes obtaining a biological sample from a subject (e.g., plasma, serum, blood, urine, or cerebrospinal fluid), contacting the sample with highly purified viral-like particles (HPVLPs) under conditions suitable for binding of a JCV antibody in the sample to an HPVLP, and detecting the level of JCV antibody binding in the sample to HPVLP. In one embodiment, determining the level of anti-JCV antibodies in the subject sample provides a method of identifying PML risk in a subject.

    摘要: Methods and compositions for determining whether a subject is at risk for PML, including subjects being treated with immunosuppressants, by determining whether the subject harbors a JCV variant with reduced binding for sialic acid relative to a normal JCV, are presented. Furthermore, combinations of JCV-VP1 sequence variations that are associated with PML and that can be used as a basis of an assay for identifying subjects susceptible to PML, subjects with PML (e.g., early stage PML), or subjects at risk of developing PML in response to an immunosuppressive treatment are provided.
