  • Publication number: 20220387505
    Abstract: The present disclosure provides ghost nanovesicles (gNVs) that are deficient in cytosolic components. Methods of making such vesicles and therapeutic uses of such vesicles are also provided. The gNVs may be used in preventing or treating conditions that may benefit from administration of the gNVs. Such conditions include conditions that involve inflammation.

  • Publication number: 20220334120
    Abstract: The present disclosure relates to a method of isolating extracellular vesicles directly from human tissues. The invention further relates to a method of identifying disease and tissue specific membrane proteins on extracellular vesicles by membrane isolation and proteomic analysis. The invention further relates to methods of diagnosing diseases by capturing extracellular vesicles by the use of disease specific membrane proteins from body fluids, and detecting or analyzing molecular signatures (proteome, DNA, and RNA) on captured extracellular vesicles. Moreover, the present invention relates to kits, apparatus and software required for implementing aforementioned methods.

  • Publication number: 20220080035
    Abstract: Non-naturally occurring vesicles derived from bacteria, e.g., pathogenic bacteria, methods for making the vesicles, and methods for using compositions of these vesicles are disclosed. Methods of using the vesicles include prevention and/or treatment of bacterial infections. Also provided herein are compositions that include vesicles derived front bacteria and tumor vesicles, methods for making the tumor vesicles, and methods for using the compositions of bacterial vesicles and tumor vesicles. Methods of using the compositions of bacterial vesicles and tumor vesicles include treatment of cancer in a subject. Tumor vesicles may be derived from cancer cells present in the subject to be treated or from a cancer cell line expressing at least one neoantigen. The neoantigen may be specific to the subject and may have been identified by sequencing of the cancer cells from the subject. The neoantigen may be a neoantigen known to be commonly expressed in a particular type of cancer.

  • Publication number: 20200063138
    Abstract: A method of producing nanovesicles comprising an oligonucleotide inhibitor to an oncogene or a proto-oncogene or the gene product thereof, said method comprises a) introducing a DNA sequence encoding an oligonucleotide capable of inhibiting a human oncogenic or proto-oncogenic transcription factor, into a mammalian cell; b) allowing the cell to express said inhibitor oligonucleotide; and c) obtaining nanovesicles containing said inhibitor oligonucleotide from said cell. Nanovesicles produced by the claimed method can be effectively and specifically targeted to e.g. cancer cells to deliver the inhibitor oligonucleotide.
