Cyclosporine 84-97 Nef Human immunodeficiency virus 1 34-37 14747548-6 2004 However, transferring these amino acids to the C terminus of HIV-1 Nef is insufficient to induce cyclosporine resistance in HIV-1. Cyclosporine 97-109 Nef Human immunodeficiency virus 1 67-70 15709044-1 2005 We have previously shown that human immunodeficiency virus type 1 (HIV-1) virions which have their own nef gene deleted and are trans complemented to contain HIV-2 or simian immunodeficiency virus (SIV) Nef become resistant to treatment with cyclosporin A. Cyclosporine 242-255 Nef Human immunodeficiency virus 1 103-106 9705263-5 1998 In single-cycle infection assays, nef-defective virions were partially resistant to cyclosporin A (CsA), a drug that inhibits the binding of CyPA to the HIV-1 Gag precursor and CyPA incorporation into virions. Cyclosporine 99-102 Nef Human immunodeficiency virus 1 34-37 9705263-10 1998 They further suggest that in addition to blocking the CyPA-Gag interaction, CsA can also inhibit HIV-1 replication through a novel mechanism involving suppression of Nef-directed enhancement of virus infectivity. Cyclosporine 76-79 Nef Human immunodeficiency virus 1 166-169 9223476-11 1997 The findings also support the hypothesis that Nef and CyPA enhance HIV-1 infectivity through independent processes and demonstrate a mechanistic difference between reduction of HIV-1 infectivity by cyclosporin A and gag mutations that decrease HIV-1 incorporation of CyPA.
