  • Patent number: 12071483
    Abstract: The present invention relates to a bi-specific antibody that specifically binds to alpha-synuclein and IGF1R, and use of the bi-specific antibody for treating or diagnosing synucleinopathies associated with alpha-synuclein or alpha-synuclein aggregates. The IGF1R portion of the bi-specific antibody acts as a shuttle to penetrate the blood brain barrier, allowing the alpha-synuclein portion to exert its action in the brain. Further, the half-life of the bi-specific antibody may be extended to maintain efficacy over time.

  • Patent number: 9834753
    Abstract: The present invention relates to a method for producing natural killer cells (hereinafter, referred to as “NK cells”), NK cells produced thereby, and a composition for treating cancers and infectious diseases containing the same. The present invention provides a method for producing NK cells, which maintain high cytotoxicity and cell viability to exhibit high therapeutic effects against cancers and infectious diseases and can be cultured ex vivo at high efficiency and high concentration. In addition, a culture method which maintains cell concentration at a constant level is used for the production of NK cells, and thus the overgrowth of the cells can be prevented so that the cells can be maintained at an optimal state. Particularly, even when the cells are thawed after freezing, the function of the cells is not impaired, and the NK cells can maintain high cell viability and cytotoxicity.
