  • Publication number: 20220262456
    Abstract: Techniques are provided for determining pan-HLA binding of viral proteins. A trained classifier model is operable to determine, independently per HLA, at least one of (a) an average binding prediction of overlapping peptides at each position of a viral protein, (b) a maximum value of a binding prediction of overlapping peptides at each position of the viral protein, (c) standard deviation of a binding prediction of overlapping peptides at each position of the viral protein, and (d) a combination of one or more of (a)-(c). A classification engine uses the classifier model to determine average binding predictions of overlapping peptides at each position of the viral protein independently for test HLA-I and HLA-II functional groupings, where a peptide is classified as a binder when an average binding prediction corresponding to the peptide satisfies a binding value threshold.

  • Patent number: 11311603
    Abstract: HIV treatment, and especially treatment of latent infected CD4 cells, can be significantly improved using a kick-and-kill approach that employs an immune stimulation component and/or HDAC inhibition as one treatment component, and that may also include a second component in which a vaccine composition, various NK cells, CAR-T cells, and/or broadly neutralizing antibodies are administered.

  • Publication number: 20220025402
    Abstract: An apparatus for electroporating cells with a cargo includes electrodes defining a path for a fluid including the cells and the cargo to flow, a power source coupled across the electrodes, and a control circuit. In some examples, the control circuit is configured to detect a decrease in an induced current due to an increase in a resistance between the electrodes, and control the power source to increase the induced current to maintain an electric field between the electrodes. A future value of the resistance between the electrodes may be predicted based on previous values of the resistance. In other examples, the control circuit is configured to detect parameters of the fluid flowing between the electrodes, and control the power source to generate or stop generating electrical pulses in response to detecting the parameters. Other example apparatuses, and methods of electroporating cells with a cargo is also disclosed.

  • Patent number: 11229668
    Abstract: Contemplated treatments and methods produce substantially increased quantities of memory T-cells and a persistent immune response by subcutaneous and/or subdermal co-administration of (1) a vector comprising a recombinant nucleic acid that encodes a cancer associated epitope, a cancer specific epitope, and/or a neoepitope, (2) an immune stimulating cytokine, and (3) a checkpoint inhibitor. Most typically, the co-administration is performed at substantially the same location, preferably within 1-21 days from each other, and the vector is an adenoviral expression vector, for example, included in a viral particle such as an AdV5 virus with a deletion of the E2b gene.

  • Patent number: 11221328
    Abstract: Detection of under-expression of selected genes in NK cells is used to confirm a hypoxic tumor microenvironment that is ordinarily suppressive with respect to ADCC and cytotoxic cell killing of NK cells. Most notably, while hypoxia is known to upregulate HIF-1? and genes under the control of HIF-1?, hypoxia in a tumor microenvironment led to under-expression of selected genes, including HIF-1?. Thus, gene expression analysis of certain genes on NK cells can be used to detect conditions in a tumor that would indicate use of haNK cells.

  • Publication number: 20210369825
    Abstract: A cancer vaccine is provided including a recombinant nucleic acid encoding a self-activating chimeric signaling protein, and especially chimeric TNF family ligand-receptor proteins, and a tumor-associated antigen. In a preferred embodiment, the cancer vaccine may further include a nucleic acid segment encoding an IL-15 superagonist. In addition, the cancer vaccine can be co-administered with a genetically modified bacteria or yeast as an adjuvant to increase the payload expression of the cancer vaccine. Advantageously, cells expressing such combination of molecules will enhance immune reaction against tumor cells. Compositions and methods are presented that allow for an enhanced immune response against a vaccine composition, and particularly a recombinant adenoviral expression system that is used as a therapeutic agent. Most preferably, immune therapeutics are administered such that a protein or nucleotide are co-located with a therapeutic antigen, preferably via co-expression of the protein.
