IFNG and malaria: Previous studies have described four HLA-A0201-restricted CD8+ T-cell epitopes within MSP1.40,68,69 A peptide mix (10 mg ml−1) corresponding to three of the four MSP1 CD8+ T-cell epitopes (291, GLHHLITEL; 374, SLLTELQQV; 437, VIYLKPLAGV)40,68,69 stimulated PBMCs from malaria semi-immune, HLA-A0201-positive individuals from Burkina Faso in the IFN‐γ ELISpot assay but not from the HLA-matched vaccinees (Fig. 9c).
