AB Inbred C.B-17-scid/scid mice accept human peripheral blood mononuclear
cell (PBMC) xenografts and are susceptible to human immunodeficiency
virus type 1 (HIV-1) infection, but low levels of PBMC engraftment
impede use of this system in HIV research. This report describes the
effect of host strain background on human PBMC engraftment and HIV
infectivity in scid mice. Back-crossing the scid mutation to the NOD/Lt
strain (designated NOD/LtSz-scid/scid) increased the percentage of
engrafted human PBMC in recipient spleens by 5- to 10-fold compared with
that in C.B-17-scid/scid stock. Four weeks after human PBMC-injected
mice were infected with HIV-1, 79% of NOD/LtSz-scid/scid spleens
harbored replicating virus compared with only 39% of spleens in
C.B-17-scid/scid mice. The NOD/LtSz-scid/scid mouse may provide a useful
small animal model for studies of HIV-1.
