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:
An antigen-presenting system (APS) comprising one or more antigens in combination with a papaya mosaic virus (PapMV) or a virus like particle (VLP) derived from papaya mosaic virus is provided. Specifically an APS comprising one or more influenza virus antigens is provided. The APS can be used, for example, as a vaccine against influenza. 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). Conjugation can be, for example, by genetic fusion with the coat protein, or binding via covalent, non-covalent or affinity means.
摘要:
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 relates to wavelength converters for optical signals, as used in telecommunications, in particular for routing signals. The invention relates in particular to a wavelength converter including an interferometer structure for delivering an output optical signal, in which converter first and second branches, including at least one first semiconductor optical amplifier, are coupled to input peripheral semiconductor optical amplifiers and/or to an output peripheral semiconductor optical amplifier, wherein the structure of the active waveguide of at least one peripheral amplifier is so designed that it has a ratio of active area to confinement factor greater than that of the active waveguide of said first amplifier.
摘要:
A photodiode (26) receives an optical input signal (P1) and an internal optical signal (P2) and supplies in response thereto an internal electrical signal (I2), which in turn controls a laser (4) which effects amplification and supplies the internal optical signal and an output signal (P3). The feedback loop formed by this photodiode and laser leads to a strong non-linearity in the variation of the output signal as a function of the input signal. The invention is useful especially in optical fiber telecommunications systems.

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:
Adjuvants comprising OmpC porin, OmpF porin, or a combination thereof, are provided. The adjuvants can be administered to a subject in combination with antigenic material in order to potentiate the immunogenic effect of the antigenic material. Also provided are products comprising antigenic material in combination with OmpC and/or OmpF, including products comprising a pre-formulated vaccine in combination with OmpC and/or OmpF. Further provided is the use of OmpC and/or OmpF to improve the effect of a pre-formulated vaccine.
摘要:
To form an integrated optical component comprising a thick waveguide coupled to a thin waveguide, the method consists in:depositing a first guiding layer of said thick waveguide on a substrate;locally etching said first guiding layer over a portion allocated both to a coupling interface and to the thin waveguide;depositing a second guiding layer on the first guiding layer and on the locally etched portion so as to form said thick waveguide in a manner such that it has a maximum thickness in a first zone, a graded-thickness section in a second zone, and a reduced-thickness section in a third zone;locally etching the second guiding layer over a portion of the third zone, said portion being allocated to the thin waveguide; anddepositing a third guiding layer in said portion of said third zone so as to form said thin waveguide.
