Abstract:
The invention relates to a pharmaceutical combined composition comprising as active ingredients an effective amount of the retroviral transmembrane envelope protein p15E of a gammaretrovirus, preferably FeLV, and an effective amount of the corresponding retroviral surface envelope protein, whereby said proteins are contained as single molecules, for inducing neutralizing antibodies which are directed against retroviral infections. The invention also relates to a method for inducing an antibody response and a method for passive immunization of a mammal by using neutralizing antibodies which are generated by administering said pharmaceutical composition.
Abstract:
The invention concerns the use of a protein derived from cancer cells, cells infected by a virus or immune cells or an inactive fragment of said protein, said protein being initially an immunosuppressive and/or an angiogenic protein with local activity whereof said properties have been inactivated by at least 70 % by a physical and/or chemical treatment, such as formolisation, carboxamidation, carboxymethylation, maleimidation or oxidation by oxygen bubbling, by genetic recombination or by adjuvant conditioning, said treatment preserving its property of being identified by antibodies directed against said protein, and preserving sufficient immunogenic properties for generating antibodies neutralising or blocking said native protein, or the use of a DNA molecule corresponding to said protein inactivated by mutation or to said inactive fragment, for obtaining a medicine designed to provide a patient with mucosal immunity based on secretion of IgA secretory antibodies, pharmaceutical compositions for the mucous membranes and IgA antibodies.
Abstract:
Novel HTLV-I and HTLV-II peptide antigens are disclosed for use in diagnostics assays for screening and confirming HTLV-I and HTLV-II antisera. The peptides are derived from analogous regions of HTLV-I and HTLV-II gp 46 envelope proteins, and are differentiated by their immunoreactivity with an HTLV-II specific monoclonal antibody and by HTLV-I and HTLV-II antisera. The peptides are also useful in vaccine compositions.

Abstract:
Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-I and corresponding mutated genes are described, having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used. Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species. Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g. HIV-1 infection.
Abstract:
The present invention is directed to an anti-prion monoclonal antibody and its use for the treatment of conditions associated with or mediated by proteins or peptides having a toxic oligomeric form. These conditions include, but are not limited to, Alzheimer's disease, frontotemporal dementias, traumatic brain injury, and chronic traumatic encephalopathy.
Abstract:
The present invention provides antibodies, or fragments thereof, for isolating and/or identifying epitopes of an endogenous retrovirus, preferably of a melanoma associated endogenous retrovirus, and hybridoma cells producing said antibodies. The antibodies are useful especially for the treatment and diagnosis of cancer. Further, the present application covers diagnostic kits for the detection of cancer cells, especially of melanoma cells and methods for cancer diagnosis using said antibodies.
Abstract:
The present invention relates generally to assays for the detection of Xenotropic Murine Leukemia Virus-related Retrovirus (“XMRV”) and diseases associated with XMRV infection. Additionally, the invention relates to specific XMRV antigens capable of inducing an immunogenic response as well as XMRV-related nucleic acids having significant diagnostic, screening, and therapeutic utilities.

Abstract:
The inventive composition comprises at least one type of antibody selected in a group (i) of anti-Env-SU MSRV/HERV-W antibodies or in a group of anti-TLR4 antibodies specifically linkable with the soluble fraction of an Env protein of MSRV/HERV-W or to a TLR4 receptor of the soluble fraction of the Env protein of MSRV/HERV-W.
Abstract:
The present invention provides antigenic polypeptides derived from the melanoma-associated endogenous retrovirus (MERV). These antigens are useful compounds for the detection of cancerous cells and melanoma-diagnosis as well as melanoma-prognosis. Furthermore these antigenic polypeptides of the present invention form the basis for anti-cancer vaccines.
