AB Replication of the IIIB strain of human immunodeficiency virus type 1
(HIV-1IIIB) in CB.17 scid/scid mice reconstituted with human peripheral
blood lymphocytes (Hu-PBL-SCID) was investigated. Hu-PBL-SCID mice could
be infected, in a dose-dependent manner, when HIV-1IIIB was injected
intraperitoneally. Replication-competent HIV-1 could be recovered from
spleen, peripheral blood, bone marrow, thymus, lymph node, and
peritoneal cavity, indicating the ability of the infection to spread to
human tissue throughout the chimeric animals. HIV-1 infection was
quantitated using p24 determination, end-point dilution culture, and
polymerase chain reaction amplification. The level of HIV-1 replication
in Hu-PBL-SCID mice was found to approximate the level reported in human
infection. No HIV-1-specific immune response was generated to this
infection, but nonspecific immune activation did occur, as also reported
in human infection. Similarities therefore exist between HIV-1 infection
of humans and Hu-PBL-SCID mice, which makes the latter an in vivo model
in which to study HIV-1 replication.
