abstract = {JC polyomavirus (JCV) establishes an asymptomatic latent
and/or persistent infection in most of the adult population.
However, in immunocompromised individuals, JCV can cause a
symptomatic infection of the brain, foremost progressive
multifocal leukoencephalopathy (PML). In the past 2 decades,
there has been increasing concern among patients and the
medical community because PML was observed as an adverse
event in individuals treated with modern (selective) immune
suppressive treatments for various immune-mediated diseases,
especially multiple sclerosis. It became evident that this
devastating complication also needs to be considered beyond
the patient populations historically at risk, including
those with hematologic malignancies or HIV-infected
individuals. We review the clinical presentation of PML, its
variants, pathogenesis, and current diagnostic approaches.
We further discuss the need to validate JCV-directed
interventions and highlight current management strategies
based on early diagnosis and restoring JCV-specific cellular
immunity, which is crucial for viral clearance and survival.
Finally, we discuss the importance of biomarkers for
diagnosis and response to therapy, instrumental in defining
sensitive study end points for successful clinical trials of
curative or preventive therapeutics. Advances in
understanding PML pathophysiology, host and viral genetics,
and diagnostics in conjunction with novel immunotherapeutic
approaches indicate that the time is right to design and
perform definitive trials to develop preventive options and
curative therapy for JCV-associated diseases.},
