A molecule or molecule complex capable of binding to TLR9 and to CD32 comprising at least one epitope of at least one antigen, and its use a medicament for the treatment of allergies.

The present invention relates to nucleotide sequences encoding Cooperia antigens, as well as to recombinant DNA molecules containing such nucleotide sequences and host cells expressing these nucleotide sequences. The invention further relates to Cooperia proteins, to methods for the production of the proteins, nucleotide sequences, recombinant DNA molecules and hosts. Furthermore, the invention relates to vaccines which induce protective immunity against infection by parasitic nematodes such as species of the genus Cooperia and to methods for preparing such a vaccine.

This invention relates to novel fusion peptides and immunogenic compositions containing the fusion peptides useful in the control and prevention of tick infestations. The invention also relates to compositions comprising said fusion peptides, methods of vaccination against tick infestation using said fusion peptides and compositions, and kits for use with such compositions and methods.

The present invention is a multivalent vaccine for immunizing an animal against filariasis. In some embodiments, the antigens of the multivalent vaccine are protein-based, DNA-based, or a combination thereof. This invention also provides a method and kit for detecting a filarial nematode and determining vaccine efficacy.

The present invention is related to the recombinant production of proteins by using a synthetic gene for high protein expression in Pichia pastoris. More specifically, the invention describes the production of Sm14 Schistosoma mansoni recombinant protein, where a synthetic gene was created to promote high expression of such protein, a gene which was cloned under control of two types of Pichia pastoris promoters: methanol-inducible promoter (AOXI) and constituent promoter (GAP). With these constructions, Pichia pastoris strains were genetically manipulated to efficiently produce vaccine antigen Sm14. The processes to produce and purify this protein from P. pastoris cells, which can be escalated for their industrial production, were also improved.

The present invention relates to vaccines comprising a ShK domain of a filarial nematode protein. These vaccines may be used for die prevention and/or treatment of filarial nematode infections. The invention also relates to novel proteins comprising a ShK domain of a filarial nematode protein and pharmaceutical compositions. The invention may be used for the prevention and/or treatment of filarial nematode infections in canine subjects, and also in human subjects.

The present invention relates to a strain of Neospora caninum for use in treating cancer or infectious diseases.

A novel method of using an aquaporin protein from Rhipicephalus microplus (RmAQP2), fragments of RmAQP2, and/or the cDNA encoding RmAQP2 and/or the fragments are described. Immunogenic composition containing recombinant RmAQP2 and/or fragments of RmAQP2 are produced and administered to an ungulate which generates an immune response to RmAQP2. After feeding female ticks on the ungulate injected with RmAQP2 and/or fragments of RmAQP2, the female ticks have lower reproductive viability because of a reduced egg mass, reduced hatching percentage, and reduced survival of larvae. Thus, administering RmAQP2 and/or RmAQP2 fragments to an ungulate can reduce the incidence of R. microplus and also reduce the incidence of tick-borne pathogens in ungulates because of the lower number of R. microplus.

The present invention relates to a composition for immunotherapy of allergic diseases, comprising house dust mite antigens and hyaluronic acid hydrogels as active ingredients. By using hyaluronic acid as a material, and forming a crosslinking with the house dust mite antigens via a photoinitiator and visible light, it can overcome the disadvantage of easy degradation and simultaneously exploit biocompatible features. Moreover, it can provide a large amount of antigens to immune cells with a single administration, and despite this, it does not induce foreign body reactions, drug reactions, or immune responses, while generating excellent immune tolerance effects. Its safety is outstanding and it does not require repeated injections over a long period. Thus, it is expected to be useful as a preventive or therapeutic agent for allergic diseases induced by house dust mites.

The invention refers to a process for the production of a continuous cell line of simile embryo stem cells, such as Amblyomma sculptum (Acari: Ixodidae), known as line IBU/ASE-16 (access number with CNCM: 1-5000) and its uses. More specifically, the invention refers to a process for the production of the line IBU/ASE-16 and their use for obtaining extracts for the production of vaccines and candidate recombinant proteins for biopharmaceuticals and acaricides, production of diagnostic kits for the detection of antigens and/or antibodies for animal and human use, obtaining clones for use in genotyping and use as a substrate for the isolation and culture of pathogens.
