Results summary.

SD50: sensitizing dose of peptide concentration required to induce half-maximum of the maximum number of specific IFN-γ secreting cells.ND: non determined.aSum of the recognition frequencies (from 0 to1) of each of the five NefBF structural domains. For example: Control group: 1(N-t)+0 (Nt-C)+0(OCC)+1(L)+0(C-t) = 2.b+/−/ = : significant increase/decrease/or no-changes in the level of cytokines produced against each of the 5 targeted peptides compared to control group.With bold and italic letter it is indicated the best response found compare to control group.
