  • Publication number: 20260201419
    Abstract: A nanoparticle for selective transfection of M2 macrophages, the nanoparticle including a lipid phase and a core that contains one or more nucleic acids. The nanoparticle selectively delivers the one or more nucleic acids to M2 macrophages in vitro and in vivo. Also provided is a therapeutic composition that contains a plurality of the nanoparticle described above and a pharmaceutically acceptable excipient. Further provided are methods for selective transfection of M2 macrophages, for converting M2 macrophages into M1 macrophages, and for treating a cancerous tumor. The methods are carried out by contacting M2 macrophages with a composition that includes a plurality of the nanoparticle mentioned above.

  • Publication number: 20260199387
    Abstract: A nanoparticle for treating hepatocellular carcinoma (HCC) in which the nanoparticle includes a lipid phase and a core that contains one or more nucleic acids encoding a chimeric antigen receptor (CAR), a T-cell engager (TCE), and/or a therapeutic gene. The CAR and the TCE each binding specifically to an HCC tumor-associated antigen and the nanoparticle selectively delivers the one or more nucleic acids to M2 macrophages in vitro and in vivo. Also provided is a therapeutic composition that contains a plurality of the nanoparticle described above and a pharmaceutically acceptable excipient. Further provided are methods for converting HCC tumor-resident M2 macrophages into M1 macrophages, and for treating HCC.

  • Publication number: 20260201059
    Abstract: A nanoparticle for treating glioblastoma multiforme (GBM) in which the nanoparticle includes a lipid phase and a core that contains one or more nucleic acids encoding a chimeric antigen receptor (CAR), a T-cell engager (TCE), and/or a therapeutic gene. The CAR and the TCE each binding specifically to a GBM tumor-associated antigen and the nanoparticle selectively delivers the one or more nucleic acids to M2 macrophages in vitro and in vivo. Also provided is a therapeutic composition that contains a plurality of the nanoparticle described above and a pharmaceutically acceptable excipient. Further provided are methods for converting GBM tumor-resident M2 macrophages into M1 macrophages, and for treating GBM.

  • Publication number: 20260187068
    Abstract: A system may perform operations including, for a given seed file, obtaining a first graph query to extract a first set of feature values from a first dataset, extracting, based on a feature calculation time, a sub-graph from the first dataset, obtaining, based on a second logic, a second graph query to extract a second set of feature values from a second dataset, and calculating a parity between the first set of feature values and second set of feature values. The operations may also include obtaining the events from a first data store, the events being filtered based on the given seed file, replaying the events backwards and extracting a third set of feature values, determining whether any of the second set of feature values do not match the second set of feature values, and updating the second set of feature values based on third set of feature values.
