英文摘要
DESCRIPTION (Adapted from the Applicant's Abstract): The overall goal of this
research is to examine the initial molecular interactions that are a critical
first step in determining the ability of a bunyavirus to infect ist mosquito
vector. Bunyaviruses are a significant cause of disease in humans and in
domestic animals worldwide. Most bunyaviruses are transmitted to humans and
animals by mosquitoes. They will use La Crosse encephalitis virus (LACV) and
its natural mosquito vector Aedes triseriatus for these studies. They will
examine the role viral glycoproteins play in the binding of virus to mosquito
midgut, in the infection of Ae. triseriatus by LACV, and in the specificity of
LACV for selected mosquito species. They will generate infectious LACV entirely
from cloned cDNA using a RNA polymerase 1-based system that was recently used
to reverse engineer influenza viruses. They will introduce specific mutatuions
and chimeric segments and genes into LACV. Based on a significant body of work
in their laboratory, they hypothesize that the G2 envelope protein of La Crosse
virus is critical for virus binding to the cells of the mosquito midgut, and
thus critical for mosquito infection. They will determine the protein sequences
of G2 that are required for biding of La Crosse virus to the midgut cells of
its natural mosquito vector, and to another permissive mosquito species. They
will determine if vector specificity, in part, is mediated by pepetide
sequences in the viral glycoproteins and if these sequences are the same that
determine virus binding to midgut cells of competent vector mosquitoes. The
development of efficient techniques to generate bunyaviruses containing
specific mutations will permit in vivo investigations of individual gene
functions in mosquito infections and in mammalian pathogenesis
