Among Herpesviruses, Human Cytomegalovirus (HCMV or HHV-5) represents a major threat during congenital or neonatal infections, which may lead to encephalitis with serious neurological consequences. However, as opposed to other less prevalent pathogens, the mechanisms and genetic susceptibility factors for CMV encephalitis are poorly understood. This lack of information considerably reduces the prognostic and/or therapeutic possibilities. To easily monitor the effects of genetic defects on brain dissemination following CMV infection we used a recently developed in vivo mouse model based on the neonatal inoculation of a MCMV genetically engineered to express Luciferase. Here, we further validate this protocol for live imaging, and demonstrate increased lethality associated with viral infection and encephalitis in mutant mice lacking Dicer activity. Our data indicate that miRNAs are important players in the control of MCMV pathogenesis and suggest that miRNA-based endothelial functions and integrity are crucial for CMV encephalitis. |
