Mutational analysis of the translational signal in the human cytomegalovirus gpUL4 (gp48) transcript leader by retroviral infection.

abstract：:Although human polyomavirus JC (JCV) is known to cause progressive multifocal leukoencephalopathy (PML) in immunocompromised individuals, the mechanism by which JCV crosses the blood-brain barrier (BBB) remains unclear. To test our hypothesis that cell-free JCV gains entry into the brain by infecting endothelial cells...
