英语翻译
The first in vitro HCV infection of fresh monocytes/
macrophages was performed using cells isolated from
buffy-coats obtained from healthy donors [122].Negative
strands of HCV were usually found for up to 10
days after infection,while positive strands were found
for up to 27 days.Quasispecies analysis showed that
the complexity of the variants decreased after culturing,
and serum and monocytes/macrophages had different
major variants.Since monocytes/macrophages
isolated from blood could be infected by HCV,a follow-
up study could find no cytopathic effects or negative
strands in Kupffer cells obtained from liver cancer
patients Daudi cells have been investigated as a host for HCV
replication.One study showed that HCV in Daudi cells
can be detected for up to 19 days,and the total amount
of HCV increased 30-fold [124].They found that
enlarged Daudi cells were positive for HCV by ISH.
They also found virus-like particles about 42 nm in size
in the cytoplasm of cells displaying early signs of apoptosis.
Membrane bound organelles were common,as
were intracytoplasmic electron dense inclusion bodies.
Immature DC and mature DC were investigated as a
target of HCV [125].HCV positive strand,were detectable
for up to 10 days PI,while negative strands could
be seen as early as day 2.In mature DC,the positive
strand was detectable for only 5 days PI,and the negative
strands on days 1 and 2 PI.They also compared
quasispecies in the HVR1 of the inoculums and immature
DC positive strands at 6 days PI and found differences,
suggesting selection of particular variants by
immature DC.
