Ligandos asociados a moléculas HLA de clase I en infecciones virales y trastornos autoinmunitarios

Abstract

CD8+ T cells identify and kill tumor and infected cells through the specificrecognition of intracellular protein-derived peptides bound to human class I majorhistocompatibility (HLA class I) molecules. HLA class I presentation of these peptideligands is key for the control of various viral infections, and it has also been involvedin autoimmune diseases like spondyloarthropathies (SpAs). In this context, theextraordinary polymorphism of HLA class I molecules determines the peptide ligandsthat can bind to the different subtypes, because just the ligands displaying theappropriate residues in the right positions, allowing the interaction with specificamino acids in the HLA molecule, can bind to each particular HLA class I subtype...
