title: Persistence of neurotropic JC virus DNA in hamster tissues six months after intracerebral inoculation.
abstract: Immunostaining and polymerase chain reaction (PCR) methods were used to examine tissues from 18 6-month-old hamsters intracerebrally inoculated with JC virus (JCV) as newborns. JCV DNA was detected in all hamster brains and urinary bladders, as well as in most kidney, adrenal gland and pancreas samples. While results from reverse transcription PCR (RNA PCR) and immunostaining suggest that T antigen transcription and protein expression were restricted to the brain, the DNA suggests that intracerebrally inoculated JCV enters the systemic circulation and latently infects organs in a tissue specific manner.
