HXB2 Location	Gag(265-282) p24(133-150) DNA(1582..1635)	Gag Epitope Map
Author Location	p24(265-282)
Epitope	WIILGLNKIVRMYSPVSI	Epitope Alignment
Subtype	C
Species (MHC/HLA)	baboon
Immunogen	vaccine
Country	South Africa
Experimental methods	Intracellular cytokine staining, T-cell Elispot
Keywords	vaccine-induced immune responses

Vaccine Details

Notes

• Immune responses in chacma baboons to candidate DNA and MVA vaccines are described. The vaccines express 5 genes (gag, RT, tat, nef, env) from HIV clade C.
• The vaccine induced strong and broad T-cell responses targeting all 5 genes, with a median of 12 targeted peptides per animal and without any single protein dominating the response. The vaccine induced strong IFN-γ and IL-2 responses with a balanced distribution in the CD8+ and CD4+ T-cell compartments. Mucosal immunity as well as long-lasting responses, present over a year after vaccination were induced.
• Responses were mapped with IFN-γ ELISPOT assay and where cells were available, the phenotype of the response was determined using intracellular cytokine staining.
• This peptide was targeted by one animal in ELISPOT and phenotyped as CD4 response. It contains previously determined CD4 epitope NKIVRMYSPTSI (DRB1*1101, DRB1*1501,DRB5*0101.
