The human polyomavirus JC (JCV) causes the central demyelinating disease progressive multifocal leukoencephalopathy in about 5% of AIDS patients. To characterize the type profile of JCV in a control population in the United States, 54 females (10 to 79 years of age; average age, 43.4 years) and 51 males (18 to 94 years of age; average age, 47.9 years) were examined for the excretion of differen...
Progressive multifocal leukoencephalopathy (PML) is a deadly demyelinating disease due to central nervous system replication of the human polyomavirus JC virus (JCV) in immunosuppressed patients. The only effective therapeutic approach is to restore anti-JCV T-cell responses. In this study, we describe a case of rapidly fatal PML with JCV T-cell anergy in a renal transplant patient treated with...
JC virus (JCV) is a neurotropic polyomavirus infecting greater than 70% of the human population worldwide during early childhood. Replication of JCV in brains of individuals with impaired immune systems results in the fatal demyelinating disease, progressive multifocal leukoencephalopathy (PML). Furthermore, JCV possesses an oncogenic potential and induces development of various neuroectodermal...
JC virus (JCV) is an ubiquitous human polyomavirus that frequently resides in the kidneys of healthy individuals and is excreted in the urine of a large proportion of the adult population. Polyomaviruses are associated with disease largely in immunocompromised individuals (progressive multifocal leukoencephalopathy). Colorectal cancers can show chromosome instability and it was hypothesized tha...
Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease triggered by infection with the human gliotropic JC virus (JCV). Due to the human-selective nature of the virus, there are no animal models available to investigate JCV pathogenesis. To address this issue, we developed mice with humanized white matter by engrafting human glial progenitor cells (GPCs) into neonatal immun...
JC virus (JCV) is a human polyomavirus known as the causative agent of the fatal demyelinating disease, Progressive Multifocal Leukoencephalopathy (PML). Further, in experimental animals this virus causes a broad range of tumors of central nervous system origin. Recent studies have suggested the association of JCV with several human tumors most notably malignant brain tumors of childhood, medul...
Virus-specific CD4(+) T cells play a central role in control of viral pathogens including JC polyoma virus (JCV) infection. JCV is a ubiquitous small DNA virus that leads to persistent infection of humans with no clinical consequences. However, under circumstances of immunocompromise, it is able to cause an opportunistic and often fatal infection of the brain called progressive multifocal leuko...
Although polyomavirus JC (JCV) is the proven pathogen of progressive multifocal leukoencephalopathy, the fatal demyelinating disease, this virus is ubiquitous as a usually harmless symbiote among human beings. JCV propagates in the adult kidney and excretes its progeny in urine, from which JCV DNA can readily be recovered. The main mode of transmission of JCV is from parents to children through...
JC virus (JCV) is a causative agent of progressive multifocal leukoencephalopathy (PML). Methyl CpG binding protein 2 (MeCP2) is a transcriptional control nuclear protein that is abundantly expressed in neurons. We previously observed that the MeCP2 protein is expressed in JCV large T antigen (TAg)-expressing glial cells in PML brains. To investigate the relationship between MeCP2 and JCV TAg, ...
