Patent number: 8454974Abstract: The present inventors developed three 4a/2a intergenotypic recombinants in which the JFH1 structural genes (Core, E1 and E2), p7 and all of or part of NS2 were replaced by the corresponding genes of the genotype 4a reference strain ED43. The 4a/2a junction in NS2 was placed after the first transmembrane domain (?), in the cytoplasmic part (?) or at the NS2/NS3 cleavage site (y). Following transfection of Huh7.5 cells with RNA transcripts, infectious viruses were produced in the ED43/JFH1-? and -y cultures only. Compared to the 2a control virus, production of infectious viruses was significantly delayed. However, in subsequent passages efficient spread of infection and high HCV RNA titers were obtained. Infectivity titers were approximately 10-fold lower than for the 2a control virus. Sequence analysis of recovered 4a/2a recombinants from 3 serial passages and subsequent reverse genetic studies revealed a vital dependence on a mutation in the NS2 4a part. ED43/JFH1-? further depended on a second NS2 mutation.Type: GrantFiled: April 11, 2008Date of Patent: June 4, 2013Assignee: Hvidovre HospitalInventors: Troels Kasper Høyer Scheel, Judith M.

Patent number: 8124348Abstract: A method and device to detect Hepatitis C (HCV) antibodies in oral fluid is provided. This method introduces a non-antibody detection molecule that labels all classes of patient antibodies in oral fluid, followed by the specific concentration of labeled anti-HCV antibodies by selective capture in a trapping zone consisting of peptide antigens derived from the HCV genome. Signal generated by the labeled antibodies present in the trapping zone is proportional to the number of anti-HCV antibodies bound to the antigens present in the trapping zone. Presence of signal derived from the capture of antibody/detection molecule complexes in the trapping zone is indicative of past exposure to HCV.Type: GrantFiled: August 5, 2004Date of Patent: February 28, 2012Inventors: Jonathan Zmuda, Lance A. Liotta, Gordon Whiteley

Publication number: 20120003277Abstract: The present invention provides methods and compositions for the stimulation of immune responses. Specifically, the present invention provides nanoemulsion compositions harboring one or more immunogens within the oil phase of the nanoemulsion and methods of using the same for the induction of immune responses (e.g., innate and/or adaptive immune responses (e.g., for generation of host immunity against an environmental pathogen)). Compositions and methods of the invention find use in, among other things, clinical (e.g., therapeutic and preventative medicine (e.g., vaccination)) and research applications.Type: ApplicationFiled: June 30, 2011Publication date: January 5, 2012Applicants: NANOBIO CORPORATION, THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: James R.
