Epitope Name SL9

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

Variant Details

Showing 1 of 4 variants.

Variant ID.	`78`
Epitope Seq.	`SLYNTVATL`
Variant Seq.	`SLfNlVATL`
Mutations	Y/F T/L
Epitope Location	Y3F T5L
HXB2 Location	Y79F T81L
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 SL9 were tested in transgenic mice. SLYNTVATL and most common mutant, SLfNTVATL, were weakly immunogenic or cross-reactive. 3 mutants, SLYNlVATL, SLfNlVATL and SiYNlVATL were highly immunogenic. Peptide SiYNlVATL with the additional L2I change allowed great cross-reactivity to the consensus.
