HXB2 Location	gp160(59-69) gp120(59-69) DNA(6399..6431)	gp160 Epitope Map
Author Location	Env(59-69)
Epitope	KAYETEVHNVW	Epitope Alignment
Epitope Name	KW11
Species (MHC/HLA)	human(A*23)
Immunogen	HIV-1 infection
Experimental methods	CD8 T-cell Elispot - IFNγ, Flow cytometric T-cell cytokine assay
Keywords	rate of progression, optimal epitope

Notes

• Correlation between HLA class I and spontaneous control of HIV-1 was significant for 7-8 epitopes when 341 chronic, HIV-infected subjects, divided into controllers and non-controllers, were tested for EliSpot responses to 257 optimally defined epitopes. 21 epitopes were associated with viral progression. Protective epitopes tend to cluster in regions of critical stability for the protein, therefore constraining escape.
• KAYETEVHNVW had a significantly positive association with HLA A*23; it was recognized by 2/11 A*23-positive subjects and 2/167 A*23-negative subjects.
• KAYETEVHNVW was significantly nonprotective, associated with HIV chronic disease progression when restricted by HLA-A*23 in a cohort of 245 controllers and 96 progressors.

Notes

• A comprehensive analysis of 160 class I T cell responses in 578 individuals from KwaZulu-Natal, South Africa was performed. Gag-specific responses were associated with lowering viremia, while Env, accessory and regulatory protein-specific responses were associated with higher viremia.
