Abstract: An anti-HIV vaccine composition is disclosed. The vaccine comprises an combination of immunogenic peptide mixtures, which mixtures may be prepared in a single synthesis. The composition collectively represents the in vivo variability seen in immunogenic epitopes from highly variable regions of HIV. Immunization with the vaccine elicits broadly reactive immunity (CTL and T helper cell responses) against the divergent strains of HIV upon which it is based. The vaccine may be formulated to target regionally distinct variability based on an HIV clade predominant in a geographical region.

Abstract: The importance of interaction between TSG101 and Vps28 in the release of HIV-1 and other viruses is disclosed. Suppressing or interfering in this interaction may inhibit HIV-1 virion release from infected cells. Agents that modulate this interaction include antibodies that bind to Vps28, polypeptides that bind to Vps28, and nucleic acids that may be used in gene therapy to interfere with the expression of wild type Vps28. Administration of such agents in vitro for screening and diagnostic purposes, and in vivo for diagnostic and therapeutic purposes, is disclosed.

Abstract: The invention relates to therapeutic polypeptides isolated from beta-human chorionic gonadotropin (?-hCG) found in human early pregnancy urine, now synthetically produced and designated Maternin. The therapeutic polypeptides and their functional equivalents are useful in treating and/or preventing various medical conditions. Examples of therapeutic effects of the therapeutic polypeptides include anti-HIV, anti-cancer, anti-wasting, prohematopoietic (e.g., anemias, radiation-mediated bone marrow damage, and trauma-mediated blood loss), and anti-angiogenic effects. The invention also provides pharmaceutical compositions comprising the therapeutic polypeptides, as well as methods for using the therapeutic polypeptides, functional equivalents and/or pharmaceutical compositions in the treatment and/or prevention of such medical conditions.

Abstract: A consensus peptide sequence designed for domain III of the envelope proteins of four serotypes of dengue virus and used in a vaccine against multiple serotypes of dengue virus is disclosed. The vaccine is able to elicit cross-neutralization antibody responses against multiple serotypes of dengue virus.
Abstract: The present invention provides artificial fusion proteins (AFPs) designed to elicit an anti-HIV immune response, as well as nucleic acid molecules and expression vectors encoding those proteins. The AFPs of the invention may comprise domains from various HIV proteins, such as Gag, Pol, Vif, and Env proteins, which are partial sequences. HIVCON is an AFP in which the HIV domains are from several HIV clade consensus sequences and which optionally contains additional domains which may be useful, for example, in monitoring expression levels or laboratory animal immune responses. Other aspects of the invention may include compositions and methods for inducing an anti-HIV immune response in a subject, preferably with a DNA prime-MVA boost strategy, and to induce a cell-mediated immune response.
Abstract: A small peptide of 10 or 11 mers, when linked to an immunogenic moiety, can protect against naferious effects of Nef protein of HIV. The vaccine is not used to induce sterilizing immunity, but to block the ability of soluble Nef protein to induce apoptosis, and to therefore alleviate lymphocyte depletion and organ damage.

Abstract: The present invention concerns polypeptides derived from a tandem repeat of apoE141-149 and their uses as medicaments. The peptides may comprise the tandem repeat, and truncations thereof, for which at least one Leucine (L) is replaced by an amino acid with a side chain comprising at least 4 carbon atoms and at least one Nitrogen atom. Such peptides are useful for preventing or treating viral infections.
Abstract: The administration of adenine nucleotides or adenosine and inorganic phosphate to a human host results in the generation of elevated liver, other organs and red blood cell adenosine 5?-triphosphate (ATP) pools as well as increased levels of ATP and adenosine in the extracellular blood plasma compartment of the blood. The present invention deals with the utilization of the elevated intracellular ATP levels and the elevated extracellular levels of ATP and adenosine for the treatment of a broad spectrum of clinical targets in HIV disease/AIDS and the achievement of decisive therapeutic gains.
Abstract: The present invention relates to an immunogenic composition. More particularly, the present invention is a composition directed to eliciting an immune response to at least one covalent binding site of myristate (SEQ ID NOS: 1-3) on the HIV matrix protein. The present invention contemplates three categories of embodiments: protein or protein fragments (SEQ ID NO: 1), messenger RNA, or DNA/RiNA (SEQ ID NOS:2-3). DNA/RNA compositions may be either naked or recombinant. The present invention further contemplates use with a variety of immune stimulants.
Abstract: New methods and reagents for vaccination are described which generate a CD8 T cell immune response against malarial and other antigens such as viral and tumour antigens.

Abstract: A method and device for determining a feline immunodeficiency virus infection or vaccination in an animal. The method includes contacting a biological sample from a felid with various FIV polypeptides and determining the binding of antibodies in the sample to the polypeptides. The determination of whether an animal is infected with FIV or has been vaccinated against FIV can be determined by measuring the animal's immune response to an FIV env polypeptide. A device for detecting FIV antibodies is provided.
Abstract: The invention relates to feline IGF-1, to the nucleotide sequence encoding this protein and to the use of IGF-1 as adjuvant for the vaccination of cats, in particular against the feline retroviruses FIV and FeLV.

The invention relates to all types of vaccines, namely inactivated, attenuated, sub-unit and recombinant vaccines. The vectors expressing IGF-1 in vivo may also be used in immunity-stimulating compositions.
