| Outline of Final Research Achievements |
In contrast to peptide Ag-presentation mediated by conventional MHC class I, a new pathway for host defense has been discovered in the monkey AIDS model, in which N-myristoylaed viral lipopeptide-specific T cell responses develop to combat against infection. We has identified novel rhesus MHC class I (LP1) molecules as lipopeptide-presenting molecules and determined the X-lay crystal structures of rhesus LP1 complexed with lipopeptide at high resolution (Morita et al. Nature Communications 7:10356,2016). In the basis of the detailed structural information, we has completed to select human LP1 candidate molecules by in silico database searching and the mutant analysis, which was likely to be capable of binding lipopeptide Ags.
