GPT and HIV-1 infection: Dual reconstituted mice regardless of HIV-1 infection showed higher ALT levels (non-infected median 84 U/l, range 46–473 U/l and infected median 75 U/l, range 25–487 U/l) than hepatocyte-transplanted 70 U/l (range 56–120 U/l, P>0.05) and non-humanized mice 26 U/ml (range 13–26 U/l).
