Human fetal thymus/liver engrafted SCID mice were constructed and studied for its susceptibility to HIVBRU infection by i.v. inoculation which seemed to represent an appropriate route of HIV infection in vivo. By the i.v. inoculation of HIV, the medulla in the engrafted thymus narrowed significantly when compared with that of the human thymic implant from virus-uninoculated mice. Further, immunohistochemical staining indicated the presence of HIV antigen predominantly in thymic epithelial cells in medulla of the engrafted thymus. Polymerase chain reaction (PCR) assays resulted in amplifications of HIV genome in the implanted grafts as well as in lymph nodes and PBMC. The virus infections to the implants were confirmed biologically by coculturing with PHA-stimulated human PBMC and the graft cells from the HIV-inoculated SCID-hu mice. Thus, the i.v. inoculation of HIV into Thy/Liv SCID-hu mice induce narrowing of medulla of the engrafted thymus and may become an efficient and useful tool for screening candidate anti-HIV agents.
