摘要:
The present invention provides for isolated nucleic acid sequences encoding viruses; isolated polypeptides comprising amino acid sequences of the virus; vectors comprising the viral nucleic acid sequences; cells comprising the vectors; antibodies and antigen binding fragments thereof which have binding specificity for the virus; methods of detecting or screening for the virus (e.g., in an individual); methods of identifying agents that inhibit the virus; methods of inducing an immune response to the virus; methods of treating disease associated with the presence of XMRV in an individual (e.g., cancer such as prostate cancer); methods of detecting asymptomatic cancer (e.g., prostate cancer); methods of identifying an individual at risk for developing cancer (e.g., prostate cancer); and kits for detecting the virus.
摘要:
The invention relates to a process for the diagnosis of a human autoimmune disease, including presymptomatic diagnosis, said human autoimmune disease being associated with human endogenous retrovirus (HERV) having Superantigen (SAg) activity, comprising specifically detecting in a biological sample of human origin at least one of the following: (I) the mRNA of an expressed human endogenous retrovirus having Superantigen (SAg) activity, or fragments of such expressed retroviral mRNA, said retrovirus being associated with a given autoimmune disease, or (II) protein or peptide expressed by said retrovirus, or (III) antibodies specific to the protein expressed by said endogenous retrovirus, or (IV) SAg activity specifically associated with said endogenous retrovirus, detection of any of the species (I) to (IV) indicating presence of autoimmune disease or imminent onset of autoimmune disease.
摘要:
This disclosure provides modified recombinant retroviruses comprisings containing a 2A-peptide or peptide-like coding sequence operably linked to a heterologous polynucleotide. The disclosure further relates to cells and vector expressing or comprising such vectors and methods of using such modified vectors in the treatment of disease and disorders.
摘要:
Molecular clones of feline leukemia virus isolates that encode (a) a prototype highly infectious, minimally pathogenic virus, (b) a variant genome that is replication-defective and associated with a fatal immunodeficiency in cats similar to AIDS (FAIDS) or (c) a chimeric genome that is replication-competent and induces FAIDS. These molecular clones may be used to generate cell lines producing infectious virus which is useful in the preparation of vaccines or in the generation of viremia or disease challenge systems.
摘要:
Particules présentant une activité de transcriptases inverses et associées à des protéines structurelles de rétrovirus de type C mammifères. L'invention concerne également de l'ADN, ainsi que des séquences d'ADN complémentaire de nouvelles particules analogues à un rétrovirus, ainsi que leurs procédés d'utilisation.
摘要:
A method for producing high-titer, helper-free infectious retroviruses is disclosed which employs a novel strategy that uses transient transfection of new retroviral producer cell lines, ecotropic line BOSC 23 and amphotropic line CAK 8, both of which cell lines and their precursor cell lines are disclosed. Because of the advantages over stable packaging cell lines, the BOSC 23 and CAK 8 transient transfection systems greatly facilitate and extend the use of helper-free retroviral vectors. The cell lines and corresponding methods possess wide application in both the medical and biotechnical fields, including gene therapy. These potential applications are disclosed and illustrated.
