Abstract: The present invention relates to the identification of the active domain of Herpoxin, a DNA virus-inhibiting-protein which was isolated from cobra venom in U.S. Pat. No. 5,648,339 and has a molecular weight of 13.5 kDa We have isolated a fragment of Herpoxin which contains the active domain and which we have named Herp. Herp mimics the activity of Herpoxin in inhibiting the replication of DNA viruses. A synthetic version of the active fragment was produced having the amino acid sequence Asn-Leu-Tyr-Gln-Phe-Lys-Asn-Met-Ile-Gln. The synthetic version of Herp consisting of ten amino acids inhibits the replication of DNA viruses such as herpes viruses types 1 and 2, cytomegalovirus and varicella zoster virus as well as Tubercle bacilli.

The prion protein dimers are highly immunogenic capable of inducing an immune response in a mammal, thus useful for prophylactic or therapeutic vaccination against diseases associated with the infectious forms of prion proteins, PrPSc, i.e. transmissible spongiform encephalopathies. Moreover, antibodies generated by using the prion protein diners as an antigen, pharmaceutical composition containing the prion protein dimers or antibodies directed against said diners as well as DNA sequences encoding the prion protein diners are described.

As a specific example of the treatment for the above-described inactivation, citation may be made of a combination of UV-irradiation using ultraviolet light at 254 nm at 4 J/m2 for 30 minutes with heating at 56° C. for 30 minutes.
Abstract: The present invention provides a rapid and sensitive method for the detection of a West Nile virus (WNV), Japanese encephalitis virus (JEV), St. Louis encephalitis virus (SLEV) and Dengue virus (DENV) and antibodies directed against thereof involving contacting a biological specimen suspected of being infected with WNV, JE, SLE or DEN with a substantially purified and isolated WNV E glycoprotein or subfragment thereof having a native conformation wherein the E glycoprotein or subfragment thereof has a reactivity with antibodies against WNV and a cross-reactivity with antibodies against JEV, SLEV and DENV. The instant invention further provides a rapid, sensitive, and consistent method for the specific detection of WNV by employing diagnostic assays having the antigen NS5 which is specifically reactive with anti-WNV antibodies but not cross-reactive with antibodies against other flaviviruses such as JEV, SLEV, or DENV.

Abstract: The present invention provides an attenuated virus, which is derived from Modified Vaccinia Ankara virus and characterized by induction of protective immunity against a lethal vaccinia virus infection in a mouse, whereby the effective amount of the MVA-BN virus, or a derivative thereof, required to confer said immunity is less than the effective amount of MVA-575 required to render said mouse immune to a lethal vaccinia virus infection, and/or the MVA-BN virus, or a derivative thereof, induces at least substantially the same level of immunity in vaccinia virus prime/vaccina virus boost regimes when compared to DNA prime/vaccinia virus boost regimes. It further describes recombinant viruses derived from this virus and the use of the virus, or its recombinants, as a medicament or vaccine. A method is provided for inducing an immune response in individuals who may be immune-compromised, receiving antiviral therapy, or have a pre-existing immunity to the vaccine virus.

Abstract: The susceptibility of human macrophages to human immunodeficiency virus (HIV) infection depends on cell surface expression of the human CD4 molecule and CC cytokine receptor 5. CCR5 is a member of the 7-transmembrane segment superfamily of G-protein-coupled cell surface molecules. CCR5 plays an essential role in the membrane fusion step of infection by some HIV isolates. The establishment of stable, nonhuman cell lines and transgenic mammals having cells that coexpress human CD4 and CCR5 provides valuable tools for the continuing research of HIV infection. In addition, antibodies which bind to CCR5, CCR5 variants, and CCR5-binding agents, capable of blocking membrane fusion between HIV and target cells represent potential anti-HIV therapeutics for macrophage-tropic strains of HIV.

Abstract: The hypervariable region (E2HV) of the putative hepatitis C virus (HCV) glycoprotein E2/NS1, between about amino acid 384 to about amino acid 414, is a rapidly evolving region of HCV, and is likely to be under positive immune selection. A newly discovered motif within this hypervariable region is immunogenic and conserved with respect to the character of the amino acids. In many isolates, this motif falls between amino acids 401 to 406 or 407. The discovery of this motif allows for additional materials and methods to treat and diagnose HCV.
