AB OBJECTIVE: By constructing SIVmac chimeric viruses having HIV-1 env more
efficient in macaque infection, we attempts to establish an experimental
infection system using macaque monkeys instead of chimpanzees. METHODS:
The chimeric viruses having LTRs, gag, pol, vif and vpx of SIVmac and
tat, rev, vpu and env of HIV-1 and additionally vpr and/or nef of either
HIV-1 or SIVmac were constructed. Growth of chimeras was examined in
human and macaque PBMC, and one of them was inoculated to macaques.
RESULTS: Growth potential of each chimera was different depending on
whether vpr and nef were from HIV-1, SIVmac or defective. When NM-3rN
carrying HIV-1 vpr and SIVmac nef was inoculated to two cynomolgus and
two rhesus monkeys, viruses were reisolated from all monkeys at 2
through 14 weeks post inoculation constantly. DISCUSSION AND
CONCLUSIONS: The results indicate the infection with NM-3rN is more
efficient than that with previously constructed chimeric viruses, and
suggest usefulness of NM-3rN as challenging virus for the HIV-1 vaccine
evaluation in macaque monkeys. Now, macaques immunized with
live-attenuated vaccine candidates were challenged with NM-3rN.
