Cross-reactive T-cell responses may underlie immunopathology in dengue haemorrhagic fever. To analyze these effects at the molecular level, the functional MHC class I molecule HLA-A*1101 was crystallized bound to six naturally occurring peptide variants from the dengue virus NS3 protein. The crystals contained high levels of solvent and required optimization of the cryoprotectant and dehydration protocols for each complex to yield well ordered diffraction, a process that was facilitated by the use of a free-mounting system. © International Union of Crystallography 2007.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyPhysics and AstronomyArticleSCOPUS10.1107/S1744309107013693
