  • Publication number: 20170362299
    Abstract: Novel synthetic biology-based ADCC technologies are provided that enhance or enable ADCC responses, for example, through a rationally-designed soluble universal ADCC enhancer protein (SUAEP) where a high-affinity CD3-binding domain is fused to a high-affinity Fc-binding domain. The SUAEP technology can be used to prevent or treat cancers, infectious, inflammatory or autoimmune diseases, and other diseases where elimination of diseased cells is desirable.

  • Publication number: 20160355515
    Abstract: The present invention relates to pyrroloquinolinyl-pyrrolidine-2,5-dione compounds in combination with chemotherapeutic agents.

  • Patent number: 9481884
    Abstract: The present invention provides a method of enabling the use of long dsRNA for gene silencing in mammalian cells through bacteria, preferably non-pathogenic or therapeutic strains of bacteria. DNA that encodes long double-strand RNAs are transformed into bacteria and processed in the bacterial cells into a mixture of smaller RNA duplexes and then released into the cytoplasm of the target cells, resulting in modulation of gene expression in the target cells. The methods overcome the incompatibility between long strong dsRNA and mammalian cells by eliminating, or mitigating, the non-specific innate immune response. The eukaryotic cells can be mammalian cells or avian cells. The gene of interest can be a mammalian, avian, bacterial, eukaryotic, or viral gene.
