摘要:
An immunopotentiating composition comprising a papaya mosaic virus (PapMV), or a virus-like particle (VLP) derived from PapMV coat protein, which is capable of functioning as an adjuvant and thus potentiating an immune response in an animal is provided. The immunopotentiating composition can further comprise an immunogen, which can be fused or otherwise linked to the VLP, or not linked to the VLP. The immunopotentiating composition is capable of potentiating a humoral and/or a cellular response in the animal and is suitable for use as an adjuvant or vaccine. Methods of potentiating an immune response in an animal comprising administering to the animal an immunopotentiating composition are also provided have application in both human and veterinary medicine.
摘要:
The immunogenic properties of the potexvirus MaI va mosaic virus (MaMV) and virus-like particles (VLPs) comprising the coat proteins of MaMV are disclosed VLPs prepared from MaMV coat proteins, methods of preparing the VLPs, MaMV coat protein polypeptides and polynucleotides encoding the coat protein are taught. Further, immunogenic compositions comprising MaMV or a VLP comprising the MaMV coat protein alone or in combination with one or more antigens and the use of said compositions to vaccinate and/or induce an immune response in an animal are also taught.
摘要:
An antigen-presenting system (APS) comprising one or more enterobacterial antigens in combination with a papaya mosaic virus (PapMV) or a virus like particle (VLP) derived from papaya mosaic virus is provided. The PapMV or VLP included in the APS is capable of potentiating an immune response against said one or more enterobacterial antigens. The APS can be used, for example, as a vaccine against enterobacterial disease, such as typhoid fever. The one or more antigens comprised by the APS can be conjugated to a coat protein of the PapMV or PapMV VLP, or they may be non-conjugated (i.e. separate from the PapMV or PapMV VLP), or the APS can comprise both conjugated and non-conjugated antigens. Conjugation can be, for example, by genetic fusion with the coat protein, or binding via covalent, non-covalent or affinity means.

The present invention relates to an immunogen-carrier having immunopotentiating or adjuvant properties. More particularly, the immunogen-carrier is a virus-like particle (VLP) from the family of potexvirus, and most particularly the papaya mosaic virus. The VLP produced by recombinant techniques is in fusion with one of its own proteins a protein immunogen. The above VLP and a protein or a protein extract from a viral, bacterial or parasital pathogen may be used as a vaccine.

The invention concerns in particular a system comprising: a first terminal (1); a second terminal (21 or 22 or 23); at least a first messaging system (31 or 32 or 33) able to transmit, to the second terminal, at least the message body of a message (10) from the first terminal; at least one device (4) controlling at least one condition (11), at least once, the said control device allowing the first messaging system to transmit to the second terminal at least the message body of the said message if the condition control result is positive, the said control device preventing the first messaging system from transmitting to the second terminal at least the message body of the said message if the condition control is negative, at least during the time for which the condition control result remains negative; at least one data server (51 or 52 or 53 or 54) external to the control device; at least one link providing communication through the Internet between on the hand the external server, or at least one of the external servers, and on the other hand the control device, the condition control device being designed to: store a message sent by the first terminal; receive at least one item of information from at least one external server; at least partially perform the condition control relating to the said message stored by means of the information received from the external server.

摘要:
A process is provided for fabricating an integrated optical circuit comprising waveguides having different structures. In this process the coupled ends of the different structures are designed to enlarge the lateral mode size of optical waves issuing from them. The optical coupling losses of the integrated optical circuit obtained in this way are considerably reduced.
