Abstract
Genes encoding the human leukocyte antigens (HLA) are associated with diverse immunological disorders, including autoimmune diseases and infections. Recently, significant progresses have been made in the HLA typing technologies through the use of next generation sequencers. The reliable platforms for the SNP-based imputation of HLA genotypes have also been established. These technical advancements should enable further identification of HLA associations with diseases. One of the remaining questions is the mechanism through which HLA confer disease susceptibility. As a first step toward comprehensive understanding of functional variations among HLA allele products, we established a protocol to analyze the HLA-binding peptides through quantification of cell-surface HLA expression in an engineered cell line. In this article, we summarize the overview of the cell-surface HLA expression assay, which we plan to use for screening and collection of HLA-peptide interaction profiles for large sets of HLA alleles and peptides.
