Abstract:
GB virus C (GBV-C or hepatitis G virus) is a flavivirus that frequently leads to chronic viremia in humans. The invention provides compositions and methods involving an anti-GBV-C antibody or other GBV-C binding agent, or a GBV-C antigen, for inhibiting and treating HIV infections.
Abstract:
Disclosed herein is the discovery of a novel hepatitis C virus (HCV) isolated from a human patient. Embodiments of the invention include HCV peptides, nucleic acids encoding said HCV peptides, antibodies directed to said peptides, compositions containing said nucleic acids and peptides, as well as, methods of making and using the aforementioned compositions including, but not limited to, diagnostics and medicaments for the treatment and prevention of HCV infection.
Abstract:
The present invention relates to a method for reducing the occurrence and severity of infectious diseases, especially infectious diseases in which lipid-containing infectious organisms are found in biological fluids, such as blood. The present invention employs solvents useful for extracting lipids from the lipid-containing infectious organism, thereby reducing the infectivity of the infectious organism. The present invention uses optimal solvent systems such that the lipid envelope around the viral particle is dissolved while the viral particle remains intact, resulting in a modified viral particle. The present invention also provides an autologous vaccine composition, comprising a lipid-containing infectious organism, treated with solvents to reduce the lipid content of the infectious organism, combined with a pharmaceutically acceptable carrier. The vaccine composition is administered to an animal or a human to provide protection against the lipid-containing infectious organism. The present invention further provides a simple, inexpensive and easy to use kit for delipidating fluids and for delipidation of lipid-containing organisms in a fluid.
Abstract:
The present invention relates to isolation of a novel Hepatitis C virus, more particularly, the present invention relates to a viral class Hepatitis C, polypeptides, polynucleotide, vaccine and antibodies derived there from.
Abstract:
The present invention is related to the branch of medicine, particularly to the new formulations of vaccine antigens.The technical objective pursued with the present invention is, precisely, the development of formulations that are able to enhance the immune response to mucosally administered antigens, minimising the number of compounds in the formulation and generating strong mucosal and systemic responses through a synergic interaction between the antigens in the formulation.These formulations enable: a) to broaden the spectrum of the anti-hepatitis B immune response, containing as main compounds HBsAg and HBcAg, b) to enhance the response against HBsAg with a viral nucleocapsid c) to generate combined vaccines through the mucosal route with HBsAg as a central antigen. Stabilizers and preservatives can be introduced.The formulations of this invention can be applied in the pharmaceutical industry as human or veterinary vaccine formulations.
Abstract:
Described herein is a method of eliciting antibodies and neutralizing of binding antibodies against a hepatitis C virus (HCV) E1E2 or E2 antigen using HCV E2 or HCV E1E2 polypeptides and/or HCV E2 or E1E2 polynucleotides. Elicitation of anti-E2 antibodies and anti-E2 NOB antibodies can be used, inter alia, to provide model systems to optimize anti-E2 antibody responses and/or anti-E2 NOB antibody responses to HCV and to provide prophylactic or therapeutic treatment against HCV infection.
Abstract:
Aspects of the present invention relate to the discovery of a novel hepatitis C virus (HCV) isolate.

Abstract:
The present invention provides synthetic immunogenic lipopeptide molecules comprising co-linear T-helper and CTL epitopes, and methods for their production and use in the generation of primary and secondary immune responses, and for the vaccination of animal subjects against particular CTL epitopes. More particularly, the present invention provides highly soluble lipopeptides wherein the lipid moiety is attached to the terminal side-chain group of an internal lysine or lysine analog, preferably to the terminal side-chain group of an internal diamino acid residue. Preferably the internal lysine or lysine analog is positioned between the T-helper epitope and the CTL epitope.
Abstract:
The present invention relates to combination vaccines comprising a conjugated polysaccharide antigen linked to a carrier protein, and wherein the carrier protein is also present as a free antigen in the vaccine composition, characterised in that the ratio of polysaccharide to protein is from 1:0:3 to 1:2. In particular, the vaccine composition of the present invention relates to a multivalent vaccine, that is a vaccine for the amelioration or treatment of more than one disease state. The present invention also relates to the production and use of such a vaccine in medicine.
Abstract:
The present invention provides vaccine compositions comprising 3 De-O-acylated monophosphoryl lipid A and QS21. The vaccines compositions are potent inducers of CTL and γ IFN responses.
