  • Publication number: 20200095586
    Abstract: A composition for treating a lysogenic virus, including isolated nucleic acid encoding two or more gene editors chosen from gene editors that target viral DNA, gene editors that target viral RNA, and combinations thereof. A composition for treating a lytic virus, including isolated nucleic acid encoding at least one gene editor that targets viral DNA and a viral RNA targeting composition. A composition for treating both lysogenic and lytic viruses, including isolated nucleic acid encoding two or more gene editors that target viral RNA, chosen from CRISPR-associated nucleases, Argonaute endonuclease gDNAs, C2c2, RNase P RNA, and combinations thereof. A composition for treating lytic viruses, including isolated nucleic acid encoding two or more gene editors that target viral RNA and a viral RNA targeting composition. Methods of treating a lysogenic virus or a lytic virus, by administering the above compositions to an individual having a virus and inactivating the virus.

  • Publication number: 20190285632
    Abstract: A diagnostic panel including a test for detecting at least one biomarker that indicates the presence of a virus. A kit including the diagnostic panel, instructions for use, materials to take and apply samples to the panel, and descriptions of biomarker levels and their meaning. A method of detecting the presence of disease, by taking a sample of an individual, applying the sample to the diagnostic panel including at least one biomarker indicative of disease, detecting the presence of at least one biomarker, comparing levels of the biomarker to a baseline, and determining if the individual has a disease. Methods of determining the stage of a disease, monitoring the progress of disease treatments, determining viral suppression or rebound, and detecting latent virus.

  • Patent number: 10279014
    Abstract: A method of eliminating the risk of JCV activation in a subject undergoing immunosuppressive therapy, by administering an effective amount of a gene editing composition directed toward at least one target sequence in the JCV genome, cleaving the target sequence in the JCV genome, disrupting the JCV genome, eliminating the JCV infection, eliminating the risk of JCV activation, and treating the subject with an immunosuppressive therapy. A pharmaceutical composition including at least one isolated nucleic acid sequence encoding a CRISPR-associated endonuclease and at least one gRNA having a spacer sequence complementary to a target sequence in a JCV DNA, the isolated nucleic acid sequences being included in at least one expression vector. Pharmaceutical compositions including at least one isolated nucleic acid sequence encoding at least one TALEN, at least one ZFN, and gene editing composition of C2c1, C2c3, TevCas9, Archaea Cas9, CasY.1-CasY.
