The present invention relates to compositions, immunogenic or vaccine compositions and pharmaceutical compositions for the prevention or treatment of canine atopic dermatitis (CAD). Furthermore, the invention provides methods for preventing or treating CAD. The compositions of the invention induce efficient immune responses, in particular antibody responses, in dogs and are, therefore, useful for the treatment and/or prevention of CAD.

The invention provides compositions of matter comprising a cowpea chlorotic mottle virus capsid protein (CCMV CP) and a ribonucleic acid, as well as methods for using such compositions. In such compositions, the cowpea chlorotic mottle virus capsid protein envelops the ribonucleic acid so as to for a capsid that can inhibit the degradation of the ribonucleic acid (e.g. by RNAses). A method of delivering a ribonucleic acid into the cytoplasm of a mammalian cell is also provided. Typically, the method comprises the steps of combining the mammalian cell with a composition of matter described herein under conditions selected to allow the cowpea chlorotic mottle virus capsid to contact the mammalian cell and deliver the ribonucleic acid into the cytoplasm of a mammalian cell.

Provided herein is a method for stabilising a single stranded RNA (ssRNA) by encapsidation of the ssRNA with a tobamovirus coat protein to obtain a pseudovirion (PsV), the method comprising expressing a tobamovirus coat protein and the ssRNA comprising a tobamovirus encapsidation origin (OriA), wherein the expressed tobamovirus coat protein interacts with the OriA sequence on the ssRNA to initiate encapsidation of the ssRNA by the tobamovirus coat protein, thereby forming a pseudovirion. The PsVs produced according to the method can be used as a diagnostic control composition, where the ssRNA is a sequence detected by a molecular diagnostic assay. The pseudovirions may also be used as a vaccine to elicit an immune response in a subject, and in pharmaceutical compositions to be administered to a subject.

The present invention relates to a technology for constructing and producing, in the form of virus-like particles (VLPs), alfalfa mosaic virus (AMV) isolated from a plant transformed using a recombinant vector for plant expression that is targeted to the chloroplast, and provides a recombinant vector comprising a polynucleotide encoding a recombinant protein in which a chloroplast-targeting protein and an AMV capsid protein are fused. The present invention also provides a transgenic plant transformed by the recombinant vector, a method for isolating and purifying a target protein from the transgenic plant, a method for producing virus-like particles using same, and the like.

The present invention relates to compositions comprising modified virus-like particles (VLPs) of Cucumber Mosaic Virus (CMV), and in particular to modified VLPs of CMV comprising chimeric CMV polypeptides which comprise a stretch of consecutive negative amino acids selected from aspartic acid and/or glutamic acid to which specific Interleukin-1 mutein antigens, IL-1-D145X antigens, are linked, as well as pharmaceutical compositions thereof, which compositions preferably serve as vaccines for generating immune responses, in particular antibody responses, against IL-1.

The present invention relates to compositions comprising modified virus-like particles (VLPs) of Cucumber Mosaic Virus (CMV), and in particular to modified VLPs of CMV comprising chimeric CMV polypeptides which preferably comprise a stretch of consecutive negative amino acids selected from aspartic acid and/or glutamic acid to which specific feline Interleukin-1 mutein antigens, fIL-1-D145X antigens, are linked, as well as pharmaceutical compositions thereof, which compositions preferably serve as vaccines for generating immune responses, in particular antibody responses, against fIL-1.

The present invention relates to compositions comprising modified virus-like particles (VLPs) of Cucumber Mosaic Virus (CMV), and in particular to modified VLPs of CMV comprising chimeric CMV polypeptides which comprise a stretch of consecutive negative amino acids selected from aspartic acid and/or glutamic acid to which canine Interleukin-1 mutein antigens, cIL-1-D145X antigens, are linked, as well as pharmaceutical compositions thereof, which compositions preferably serve as vaccines for generating immune responses, in particular antibody responses, against cIL-1.

The present invention relates to virus-like particles of plant virus Cucumber Mosaic Virus (CMV), and in particular to modified VLPs of CMV comprising Th cell epitopes, in particular universal Th cell epitopes. Furthermore, these modified VLPs serve as, preferably, vaccine platform, for generating immune responses, in particular antibody responses, against antigens linked to said modified VLPs. The presence of the Th cell epitopes, in particular universal Th cell epitopes, led to a further increase in the generated immune response.
