HXB2 Location	Vpr(33-43) DNA(5655..5687)	Vpr Epitope Map
Author Location	Vpr(33-43)
Epitope	HFPRIWLHGLG	Epitope Alignment
Epitope Name	HG11
Subtype	B
Species (MHC/HLA)	human
Immunogen	HIV-1 infection
Patient MHC/HLA	A26, A32, B27, Cw1, Cw2
Experimental methods	CD8 T-cell Elispot - IFNγ
Keywords	HIV exposed persistently seronegative (HEPS), acute/early infection

Notes

• CTL responses were measured in a highly exposed patient who was seronegative for 2 years, both before and after seroconversion. CTL responses after seroconversion were stronger, and more of the responses were associated with protective HLA allele B27.
• HFPRIWLHGLG was part of a pool that was not recognized by the HEPS patient before seroconversion; it elicited an EliSpot response after seroconversion. The patient's consensus sequence at day 24 after seroconversion was HFPRpWLHGLG.
