A coat protein of Junonia coenia densovirus (JcDNV) is used to deliver attached peptide insect toxin across the gut epithelium of a fall armyworm, Spodoptera frugiperda. A fusion protein comprising VP4 attached to an insect toxin via a peptide linker is developed. A composition comprising a JcDNV coat protein attached to an insect toxin via a peptide linker can be used for insect pest control.

The disclosure relates to compositions, methods, and processes for the preparation, use, and/or formulation of adeno-associated virus capsid proteins, wherein the capsid proteins comprise targeting peptide inserts for enhanced tropism to a target tissue.

The present invention provides novel mRNA elements capable of forming hairpin, double-stranded RNA structures independent of other non-coding RNAs. These mRNAs are stably expressed, lack polyadenylation tails, and allow minimal protein translation except when in the presence of specific proteins. Also provided, are compositions and kits comprising the mRNA element, as well as methods for its use in the regulation of protein translation. Advantageously, the disclosed elements represent a novel tool useful in regulating the expression of a wide variety of proteins of interest.

The present invention relates to the field of (vector) vaccines, and especially to an enhanced arrangement of nucleotide sequences for expressing a Paramyxoviridae virus containing an exogenous gene of interest. The present invention further concerns related expression cassettes and vectors, which are suitable to express genes of interest, especially antigen encoding sequences. The viral vectors of the present invention are useful for producing an immunogenic composition or vaccine.

The present invention provides: a recombinant expression vector comprising a gene encoding a porcine parvovirus VP2 protein; a recombinant plant or a recombinant insect cell transformed with the vector; and a vaccine composition for a porcine parvovirus and a composition for diagnosing porcine parvovirus, both of which contain a porcine parvovirus VP2 protein obtained from the recombinant plant or the recombinant insect cell. When the recombinant plant or recombinant insect cell of the present invention is used, the porcine parvovirus antigenic protein can be produced with high efficiency, and the porcine parvovirus antigenic protein production method using the recombinant plant or recombinant insect cell has excellent safety and stability compared with other antigen production methods.
