Phosphorylated alpha-enolase induces autoantibodies in HLA-DR8 pancreatic cancer patients and triggers HLA-DR8 restricted T-cell activation

Highlights • In pancreatic ductal adenocarcinoma the glycolytic enzyme ENOA is upregulated. • Up-regulation elicits the production of ENOA1,2 autoantibodies. • HLA-DRB1*08 allele is more frequent in PDAC patients with autoantibodies. • P-ENOA peptide binds HLA-DR8 antigen and activates specific CD4+...
