Variants

TLNAWVKai susceptible form

Epitope Name TV9

Species (MHC/HLA) human, transgenic mouse(A2)

Variant Details

Showing 1 of 3 variants.

Variant ID.	`82`
Epitope Seq.	`TLNAWVKVV`
Variant Seq.	`TLNAWVKai`
Mutations	V/A V/I
Epitope Location	V8A V9I
HXB2 Location	V158A V159I
Mutation Type	SF: susceptible form
Method	CD8 T-cell Elispot - IFNy, Chromium-release assay
Note	To identify immunogenically optimized epitopes for use in vaccines, mutants of TV9 were tested in transgenic mice. Natural TV9 mutants tested in transgenic HLA-A*02 mice showed the following responses - the common mutant V9I, TLNAWVKVi was less immunogenic and had low cross-reactivity. TLNAWVKaV (most cross-reactive) and TLNAWVKai were highly immunogenic and cross-reactive to the consensus.
