  • Patent number: 11969397
    Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

  • Publication number: 20230320127
    Abstract: An organic light emitting diode device can have an enhanced thin film encapsulation layer for preventing moisture from permeating from the outside. The thin film encapsulation layer can have a multilayered structure in which one or more inorganic layers and one or more organic layers are alternately laminated. A barrier can be formed outside of a portion of the substrate on which the organic light emitting diode is formed. The organic layers of the thin film encapsulation layer can be formed inside an area defined by the barrier.
