  • Publication number: 20240141347
    Abstract: An RNA delivery system for the treatment of Huntington's disease. The system comprises a viral vector, the viral vector carries RNA fragments capable of treating Huntington's disease, the viral vector is capable of enrichment in organ tissues of a host and endogenously and spontaneously forming a complex containing the RNA fragments capable of treating Huntington's disease in the organ tissues of the host, and the complex can deliver the RNA fragments into a target tissue to treat Huntington's disease. The safety and reliability of the RNA delivery system for the treatment of Huntington's disease have been fully verified. The system has good medicinal properties, strong versatility, and has economic benefits and application prospects.

  • Publication number: 20240141361
    Abstract: Provided are a gene circuit, an RNA delivery system and the use thereof. Specifically, the gene circuit comprises at least an RNA fragment capable of inhibiting gene expression and/or a targeting tag having a targeting function. The gene circuit can be delivered to a host, enriched in organ tissues of the host and self-assembled to form a complex structure, and inhibits gene expression by means of the RNA fragment, thereby treating diseases. The delivery system comprises the gene circuit and a delivery carrier capable of delivering the gene circuit to organ tissues of a host for enrichment. The provided gene circuit has a targeting function and a treatment function, can quickly and accurately reach target organs and target tissues to exert a treatment effect, and is highly efficient with good results. The safety and reliability of the provided RNA delivery system are fully verified, and the RNA delivery system has good druggability, high universality, and great economic benefits and application prospects.

  • Publication number: 20240141344
    Abstract: Provided are an RNA plasmid delivery system and an application thereof. The RNA plasmid delivery system comprises a plasmid carrying an RNA fragment required to be delivered; the plasmid can be enriched in an organ tissue of a host, and spontaneously forms an exosome containing the RNA fragment in the organ tissue of the host, and therefore can enter and be combined with a target tissue to deliver the RNA fragment into the target tissue. The RNA delivery system is safe, reliable, good in druggability, and strong in universality.

  • Publication number: 20240141380
    Abstract: Provided are a viral vector-based RNA delivery system and a use thereof. The RNA delivery system comprises a viral vector. The viral vector carries an RNA fragment needing to be delivered, and can be enriched in organ tissues of a host. In the host organ tissues, the viral vector can endogenously and spontaneously form a composite structure containing the RNA fragment. The composite structure can enter and bind to target tissues, and feed the RNA fragment into the target tissues. The viral vector has a targeting tag. The composite structure is an exosome. The viral vector RNA delivery system is safe and reliable, and has good druggability and high universality.

  • Patent number: 9799041
    Abstract: A method includes determining a plurality of data points, determining a distance between each data point and each of the other plurality of data points, choosing a first one of the plurality of data points, identifying all of the other plurality of data points within a maximum distance of the chosen data point, repeating steps the previous steps to choose a different one of the plurality of data points until all of the data points have been chosen, identifying one or more clusters each having a predefined minimum number, K, of data points within a predefined search radius and analyzing the one or more clusters with respect to K linkages.
