RSLYNTVATLY

Epitope Alignment

Variants

RSLYNTiAvLY diminished HLA binding or increased off-rate; diminished response; escape documented in this paper

Epitope Name RY11

Species (MHC/HLA) human(A*02:01, A*30:02)

Variant Details

Showing 1 of 15 variants.

Variant ID.	`2975`
Epitope Seq.	`RSLYNTVATLY`
Variant Seq.	`RSLYNTiAvLY`
Mutations	V/I T/V
Epitope Location	V7I T9V
HXB2 Location	V82I T84V
Mutation Type	DHB: diminished HLA binding or increased off-rate DR: diminished response E: escape documented in this paper
Epitope Subtype	B
Variant Subtype	B
Method	CD8 T-cell Elispot - IFNy, HLA binding
Note	Variant RSLYNTiAvLY did not bind to HLA-A*02 in vitro, and it showed complete abrogation of ex-vivo EliSpot responses in 1/3 chronically-infected, untreated patients; diminished response in another patient; and no change in the third as compared to WT RY11. The authors designate both V82I and T84V mutation-containing peptides to be escapes.
