Nucleic acid homology of murine type-C viral genes.
The nucleic acid sequence homology between various murine, endogenous type-C viruses (three host range classes of BALB/c virus, the AT-124 virus, and the CCL 52 virus) and two laboratory strains of murine leukemia virus (Rauscher and Kirsten) was determined by DNA:RNA hybridization. The viral sequences exhibit varying degrees of partial homology. DNA:DNA hybridizations were performed between [(...
متن کاملRadioimmunoassay of Mammalian Type C Viral Proteins
A radioimmunoassay specific for a murine leukemia virus structural protein, the gs antigen, detects an antigenic reactivity in normal murine cells in culture and natural tissues. The assay was shown to measure an antigen that is highly related to the virion protein as shown by absorption tests, immunoadsorbent chromatography, and by analysis of linearized dose-response curves. These findings co...
متن کاملEvolution of type C viral genes: I. Nucleic acid from baboon type C virus as a measure of divergence among primate species.
Hybridization studies with a [(3)H]DNA probe from an endogenous baboon type C virus were used to detect nucleic acid sequences of type C virus in primate cellular DNA. Sequences related to those of the baboon type C virus are found in all other Old World monkey species, higher apes, and man.
متن کاملPhysical map of infectious baboon type C viral DNA and sites of integration in infected cells.
Three species of unintegrated viral DNAs were found in permissive cells infected with baboon type C virus. The major species was a 9.0-kilobase (kb) linear DNA that was infectious. A restriction endonuclease map of this DNA was constructed and oriented with respect to the viral RNA. The linear DNA had a 0.6-kb sequence repeated at each terminus. These terminal repeat sequences were required for...
متن کاملC-Type Lectin Receptors in Antiviral Immunity and Viral Escape
C-type lectin receptors (CLRs) are important pattern recognition receptors involved in recognition and induction of adaptive immunity to pathogens. Certain CLRs play an important role in viral infections as they efficiently interact with viruses. However, it has become clear that deadly viruses subvert the function of CLRs to escape antiviral immunity and promote infection. In particular, virus...
