Notes

HLA-B*0702 is associated with rapid progression to disease in B-clade HIV-1 infected subjects. B*0702+ C-clade infected subjects however are not associated with a high viral setpoint of infection, and target a broader range of Gag epitopes at higher magnitudes. Increased magnitudes of Nef-specific responses were also detected in C-clade infected B*0702+ cohorts. A C-clade specific, B*0702-restricted novel p17 epitope, RPGGKKHYM, RM9, was defined.
Epitope RM9, RPGGKKHYM, a novel Gag epitope is not targeted in B-clade infections. The B-clade consensus epitope differs at H7K and M9K, and is RPGGKKkYk (RK9). RM9 but not RK9 is stable in complex with HLA-B*0702; while the binding affinity of RM9 to B*0702 is K_d = 14nM, that of RK9 is >20,000 nM; RM9-specific CTL do not cross-recognize RK9. 7% of B-clade infected can recognize C-clade RM9, but that is significantly less than the >50% C-clade-infected subjects who do. RM9 is contained within OLP3, EKIRLRPGGKKHYMLKHL.

Epitope GL9, GPSHKARVL, (3S), a C-clade Gag epitope was the only one studied that was associated with a low viral setpoint in C-clade infected subjects. In B-clade infections GL9-3S, though recognized, had a high frequency of its S357G escape mutant, at 70% escape for B*0702+ subjects versus 43% escape in B*0702-, B-clade infected subjects. GL9 was also cross-recognized to equal extents as its B-clade variant, (3G), at 55% and 29% in C- or B-clade infected cohorts. The B-clade consensus epitope differs at S3G, and is GPgHKARVL. The binding affinity of GL9-3S to B*0702 was K_d = 9 nM, while that of variant GL9-3G is 342 nM. GL9 is contained within OLP48, ACQGVGGPSHKARVLAEA.
