Variant Details

Showing 1 of 3 variants.

Variant ID.  80
Epitope Seq.  TLNAWVKVV
Variant Seq.  TLNAWVKVi
Mutations V/I
Epitope Location V9I
HXB2 Location V159I
Mutation Type DR: diminished response
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.
