  • 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.

  • Patent number: 11626709
    Abstract: The embodiment relates to a light-emitting device in which a positional relationship between a modified refractive index region's gravity-center position and the associated lattice point differs from a conventional device, and a production method. In this device, a stacked body including a light-emitting portion and a phase modulation layer optically coupled to the light-emitting portion is on a substrate. The phase modulation layer includes a base layer and plural modified refractive index regions in the base layer. Each modified refractive index region's gravity-center position locates on a virtual straight line passing through a corresponding reference lattice point among lattice points of a virtual square lattice on the base layer's design plane. A distance between the reference lattice point and the modified refractive index region's gravity center along the virtual straight line is individually set such that this device outputs light forming an optical image.
