Effects of MG132 on the infectivity of pseudotyped HIV-1 particles. (A) HIV-1(VSV) pseudotyped particles were produced by the transfection of 293T cells with Env-defective variants of the indicated proviral DNAs and the VSV-G expression vector pHCMV-G (27). (C) HIV-1(A-MLV) particles were produced by cotransfection of Env-defective proviral DNAs with the amphotropic murine leukemia virus Env expression vector pSV-A-MLV-env (13). Panels B and D show the ratios of wild-type/Nef-defective HIV-1 infectivity corresponding to the results in panels A and C, respectively. Error bars indicate standard deviations.
