I am not an expert in the field, but your memory did not fail you. Since 1988,
a couple of SCIDhu mice were developed and infected with HIV, the latest being
described in a J. Exp. Med paper (Feb 1994). In a nutshell, these studies show
that intraimplant inoculation with HIV leads to infection of the implanted
human thymus, and that there is a depletion of thymocytes. Moreover, it has
been shown that an implanted human thymus can become infected after peripheral
exposure to HIV.
This is all I know on this one. I am not aware of any serious pathological
studies on the above mice. If somebody else knows better, I would appreciate
