A liposomal vaccine composition comprises a -amyloid (A)-derived peptide antigen displayed on the surface of the liposome. The vaccine composition also comprises a peptide comprising a universal T-cell epitope encapsulated within the liposome. The vaccine composition also comprises an adjuvant, which may form part of the liposome and may be displayed at least in part on the surface of the liposome. These vaccine compositions are used for treating, preventing, inducing a protective immune response against or alleviating the symptoms associated with an amyloid-beta associated disease or condition or a condition characterised by, or associated with, loss of cognitive memory capacity in a subject. The vaccine compositions may be provided as a kit. Related methods of producing a liposomal vaccine composition are also provided.

Disclosed herein are fusion proteins comprising a truncated thrombostasin protein having at least 85% sequence homology to a thrombostasin protein, wherein the thrombostasin protein has a carboxy terminal deletion; and a fusion partner protein that is a non-thrombostasin protein. Further disclosed are vaccine compositions thrombostasin proteins having a comprising a carboxy terminal deletion, and methods for inhibiting a response to a thrombostasin protein in a host in need thereof, comprising the disclosed fusion proteins or vaccine compositions. Further disclosed are methods for the preparation of a fusion protein composition.

The present invention provides methods, compositions, systems, and kits comprising nano-satellite complexes and/or serum albumin carrier complexes, which are used for modulating antigen-specific immune response (e.g., enhancing anti-tumor immunity). In certain embodiments, the nano-satellite complexes comprise: a) a core nanoparticle complex comprising a biocompatible coating surrounding a nanoparticle core; b) at least one satellite particle attached to, or absorbed to, the biocompatible coating; and c) an antigenic component conjugated to, or absorbed to, the at least one satellite particle component. In certain embodiments, the complexes further comprise: d) a type I interferon agonist agent. In some embodiments, the serum albumin complexes comprise: a) at least part of a serum albumin protein, b) an antigenic component conjugated to the carrier protein, and c) a type I interferon agonist agent.

Compositions, devices, kits and methods for the detection of Aelurostronglylus abstrusus (A. abstrusus), a feline lungworm species in mammals, is provided. More particularly, polypeptides and polypeptide compositions, antibodies and antibody compositions, devices, kits, and methods for detecting the presence or absence of A. abstrusus antibodies in a sample from a mammal that may also include one or more other feline lungworms, roundworm, hookworm, and whipworm antigens, for diagnosing A. abstrusus lungworm infection and for detecting, diagnosing and treating A. abstrusus lungworm infection. Compositions including polypeptide or polynucleotide immunogens, vaccines, and methods for treating and/or preventing feline lungworm infections in mammals are also provided.

The invention relates to antigenic polypeptides derived from a naturally occurring R. microplus protein, and nucleic acids encoding such polypeptides. The polypeptides elicit an immune response which, in turn, produces detrimental effects in R. microplus feeding on vaccinated cattle. Thus, the present disclosure provides novel vaccines to protect cattle from R. microplus infestation.

The present invention is applied to the field of Biotechnology and Immunology and refers to combinations of immunogenic peptides, chimeric peptides, compositions that comprise them and the uses thereof for control of ticks, particularly ticks of the species Rhipicephalus microplus. The present invention further provides kits containing the combinations, chimeric peptides and/or compositions comprising the combinations of immunogenic peptides, and a method for inducing immune response in animals, particularly bovines.

Compositions of either the Rm86Texas protein from a Texas outbreak strain of the southern cattle fever tick, Rhipicephalus microplus, or a nucleic acid construct incorporating a nucleic acid sequence encoding this Rm86Texas protein, are effective for eliciting a protective immune response in non-bovine animals. The Rm86Texas protein is immunogenic and can be administered as a protein vaccine, or in the alternative, the nucleic acid construct can be utilized as a DNA vaccine. Induction of the immune response significantly reduces or eliminates the infestation of treated, non-bovine animals with ticks. Moreover, as ticks are vectors of a variety of pathogens, the reduction in the incidence of tick infestation afforded by the vaccines may concurrently reduce the incidence of diseases caused by these pathogens in susceptible animals.

Substantially purified salivary Lu. longipalpis polypeptides, and polynucleotides encoding these polypeptides are disclosed. Vectors and host cells including the Lu. longipalpis polynucleotides are also disclosed. In one embodiment, a method is disclosed for inducing an immune response to sand fly saliva. In other embodiments, methods for treating, diagnosing, or preventing Leishmaniasis are disclosed.

The present invention describes vaccine compositions for treatment and/or prevention against sea lice infestation in salmon. The present invention further describes nucleic acids, host cells, vectors and methods of using said vaccine for the prevention and/or treatment of sea lice infestation in salmon.

A liposomal vaccine composition comprises a ?-amyloid (A?)-derived peptide antigen displayed on the surface of the liposome. The vaccine composition also comprises a peptide comprising a universal T-cell epitope encapsulated within the liposome. The vaccine composition also comprises an adjuvant, which may form part of the liposome and may be displayed at least in part on the surface of the liposome. These vaccine compositions are used for treating, preventing, inducing a protective immune response against or alleviating the symptoms associated with an amyloid-beta associated disease or condition or a condition characterised by, or associated with, loss of cognitive memory capacity in a subject. The vaccine compositions may be provided as a kit. Related methods of producing a liposomal vaccine composition are also provided.
