Penetration and propagation of herpesviruses in the nervous system
require the action of several glycoproteins. To assay for a
function of glycoproteins gC, gK, and gL in the neuroinvasiveness of
pseudorabies virus (PrV), deletion mutants lacking one of these glycoproteins and corresponding rescuants were inoculated in the nasal
cavity of adult mice. We demonstrate that the lack of gL almost
prevented the virus from penetrating and propagating in trigeminal,
sympathetic, and parasympathetic tracks innervating the nasal cavity,
while the lack of gC and gK only slowed the invasion of the nervous
system. The conclusion of this and previous studies is that only gB,
gD, gH, and gL are indispensable for penetration into neurons, while
gB, gH, and gL (and, in some categories of neurons, also gE and gI) are
necessary for transneuronal transfer in the mouse model. The deletion
of other glycoprotein genes has little effect on PrV neuroinvasiveness
although it may affect the dissemination of the virus.
