  • Publication number: 20230118024
    Abstract: The antibodies of the present invention have specific binding activity to HLA-DQ2.5 and may have binding activity to HLA-DQ2.2 and/or HLA-DQ7.5, but substantially no binding activity to HLA-DQ8, HLA-DQ5.1, HLA-DQ6.3, HLA-DQ7.3, HLA-DR, HLA-DP, or a complex of the invariant chain (CD74) and HLA-DQ2.5. The antibodies bind to HLA-DQ2.5 in the presence of a gluten peptide such as gliadin, i.e., bind to HLA-DQ2.5 forming a complex with the gluten peptide. The antibodies have neutralizing activity against the binding between HLA-DQ2.5 and TCR, and thus block the interaction between HLA-DQ2.5 and an HLA-DQ2.5-restricted CD4+ T cell. The antibodies do not undergo rapid internalization mediated by the invariant chain.
