From: Human immunome, bioinformatic analyses using HLA supermotifs and the parasite genome, binding assays, studies of human T cell responses, and immunization of HLA-A*1101 transgenic mice including novel adjuvants provide a foundation for HLA-A03 restricted CD8+T cell epitope based, adjuvanted vaccine protective against Toxoplasma gondii

Addition of peptides to pool robustly protects HLA-A*1101 mice against Type II parasite challenge. HLA-A*1101 transgenic mice were immunized with PBS (controls) or peptide pool with PADRE and Pam2Cys in GLA-SE. Splenic T cells were isolated 10-14 days post immunization and exposed to each peptide in an ex vivo IFN-γ ELISpot assay (Figure 7a). HLA-A*1101 transgenic mice immunized with peptide pool and adjuvants were protected compared with control mice inoculated with PBS when they were challenged with 10,000 Pru (Fluc)-T. gondii luciferase expressing parasites (Figure 7b). Mice were immunized and in a subgroup immune function was studied at the same time as the challenge shown was performed. Differences between control and immunized mice were significant (p < 0.0064 using natural log transformed data and two-sample t test).
