  • Patent number: 11529511
    Abstract: Certain substances (e.g., large molecules) that ordinarily cannot traverse the cell membrane of cells can be introduced into cells by applying an alternating electric field to the cell for a period of time, wherein the frequency of the alternating electric field is selected so that application of the alternating electric field increases permeability of the cell membrane. Once the permeability of the cell membrane has been increased, the substance is able to cross the cell membrane. This approach is particularly useful in the context of cancer cells (e.g., glioblastoma).

  • Publication number: 20210077554
    Abstract: Methods of treatment utilizing complimentary transgenic oncolytic virus and engineered CAR T-cells are provided. Oncolytic viruses are engineered such that they can express an ectopic antigen on neoplastic cells. CAR T-cells are engineered to recognize the ectopic antigen are utilized in various methods of treatment. Accordingly, a transgenic oncolytic virus can be administered to a neoplasm to induce expression of an ectopic antigen and then that neoplasm can be treated with a complimentary CAR T cells engineered to recognize the ectopic antigen to induce an immune response against the neoplasm, resulting in neoplastic cell death and/or clearance.

  • Publication number: 20200323999
    Abstract: A nanodroplet particle useful as an imaging contrast agent comprises a saline solution that upon irradiation with a radiofrequency energy generate a detectable acoustic signal. The saline solution nanodroplets can be encapsulated by a fluorinated shell that maintains the integrity of the nanodroplets. The saline solution and the fluorinated shell form the nanoparticles when sonicated, for example, in the presence of a non-ionic surfactant to form double-emulsion compositions. The nanoparticles of the disclosure may be advantageously useful as imaging contrast agents suitable for providing a detectable signal when administered to an animal or human subject. The nanoparticles can be conjugated to targeting agents such as biomarker or cell-specific ligands so that the nanoparticles may be concentrated to a desired target such as, but not limited to, a suspected tumor.

  • Patent number: 10675366
    Abstract: The present disclosure provides a positron emission tomography (PET)-detectable 1-((2-fluoro-6-[18F]fluorophenyl)sulfonyl)-4-((4-methoxyphenyl)sulfonyl)piperazine ([18F]DASA-23) probe that can selectively bind to the pyruvate kinase variant M2 (PKM2) found in cancer cells, such as of human glioma. Given the importance of PKM2 in the regulation of tumor metabolism, there is an on-going need to non-invasively measure its expression through the development of PKM2-specific radiopharmaceuticals. Precursors useful for the synthesis of the radiolabeled [18F]DASA-23-PKM2-specific probe and related compounds, and their methods of synthesis, are provided. Since the half-life of the 18F isotope is approximately 110 min, it is advantageous for a practitioner to attach the radionuclide to the precursor shortly before administration. Therefore, a precursor compound suitable for receiving the radionuclide and capable of specifically binding to the PKM2 variant can be provided.
