Upon PBMC stimulation with Gag-peptides, p27Gag-specific T cell responses (range 0.06.5 of IFN-g producing T lymphocytes) had been identified in all animals (Fig. 2A). To examine responses to CE, PBMC were stimulatedIMPROVED Gag CONSERVED ELEMENT IMMUNIZATION REGIMENFIGURE 1. Derivation of SIV p27Gag CE and conservation relative to HIV-1 and SIV strains from several species. All sequences were compared with HIV-1 p24CE1 (20), having a dot indicating homology. Toggle positions that distinguish SIV p27CE1 and p27CE2 are shown in red form. Amino acid variations that distinguished the SIV and HIV-1 CE but were conserved in other SIV strains are shown in blue kind. A protocol of like only 1 toggle web site per CE was adhered to except for CE4, in which two further amino acids had been substituted for the reason that those amino acid variants were always found collectively inside the database. No toggled amino acid was incorporated for CE1, CE6 or CE7 on account of the comprehensive conservation observed in these segments among available SIV sequences. The sequences shown correspond to the consensus of those obtained in the Los Alamos HIV sequence database. Blank positions indicate that sequences corresponding for the CE area had been not available.
