Notes

• Cross-clade CTL responses in 10 non-B HIV-1 infected individuals were evaluated. T-cell reactivity was tested against peptide pools of clade B Gag, Pol, Nef, Rev and Tat. Nine individuals demonstrated cross-reactive T-cell responses to clade A, B, and C Gag pools; 6/7 patients that responded to Nef-B also reacted to clade A and C Nef pools. An inverse correlation was observed between the sequence divergence of the HLA class I restricted epitopes and the height of the T-cell responses, which in Gag could be explained through variations in the HLA-anchor residues. 42% of the responses were directed to regions containing new epitopes.
• This previously described epitope was embedded in a B clade peptide that was recognized by T-cells from an infected person carrying subtype D Gag. The autologous epitope sequence had an K5N change, RPGGnKKYKL.

The autologous epitope sequence had dramatic changes, the epitope GSEELRSLY peptide was GtegikSLh, and so likely not the actual reactive epitope in the larger peptide.

The autologous epitope sequence in this person differed from the known epitope by one amino acid, E1D, dTINEEAAEW. It was also recognized in a person carrying a subtype D gag, and in this case the autologous sequence matched the epitope. This was also predicted to possibly be a B58 cross-presented epitope in another subtype D Gag infected person based on peptide reactivity and a known B58 motif.

Notes

• Cross-clade CTL responses in 10 non-B HIV-1 infected individuals were evaluated. T-cell reactivity was tested against peptide pools of clade B Gag, Pol, Nef, Rev and Tat. Nine individuals demonstrated cross-reactive T-cell responses to clade A, B, and C Gag pools; 6/7 patients that responded to Nef-B also reacted to clade A and C Nef pools. An inverse correlation was observed between the sequence divergence of the HLA class I restricted epitopes and the height of the T-cell responses, which in Gag could be explained through variations in the HLA-anchor residues. 42% of the responses were directed to regions containing new epitopes.
• This previously described epitope was embedded in a B clade peptide that was recognized by T-cells from an infected person carrying subtype D Gag. The autologous epitope sequence in this person matched the known epitope. In another D subtype infected individual, it was predicted to be a B53 epitope based on HLA typing of the individual and motifs within the reactive peptide.

HXB2 Location	Gag(483-492) p2p7p1p6(120-129) DNA(2236..2265)	Gag Epitope Map
Author Location	p2p7p1p6
Epitope	LYPLASLRSL	Epitope Alignment
Subtype	D
Species (MHC/HLA)	human(A24)
Immunogen	HIV-1 infection
Patient MHC/HLA	A23, A24, B35, B58, Cw4, Cw7
Country	Democratic Republic of the Congo
Experimental methods	CD8 T-cell Elispot - IFNγ
Keywords	subtype comparisons, computational epitope prediction

Notes

• Cross-clade CTL responses in 10 non-B HIV-1 infected individuals were evaluated. T-cell reactivity was tested against peptide pools of clade B Gag, Pol, Nef, Rev and Tat. Nine individuals demonstrated cross-reactive T-cell responses to clade A, B, and C Gag pools; 6/7 patients that responded to Nef-B also reacted to clade A and C Nef pools. An inverse correlation was observed between the sequence divergence of the HLA class I restricted epitopes and the height of the T-cell responses, which in Gag could be explained through variations in the HLA-anchor residues. 42% of the responses were directed to regions containing new epitopes.
• Predicted epitope based on an HLA motif embedded in a reactive peptide from a person carrying a D clade Gag.
