摘要:
A novel chimeric envelope coat protein of rabies virus was strategically designed to express a chimeric G protein at a high level in transgenic plants. A gene was theoretically designed and chemically synthesised to encode the chimeric G protein and expressed at high level in plant tissue. The gene was expressed in transgenic tobacco plants to examine its therapeutic efficacy against infection by rabies virus. The chimeric G protein was enriched in plant membranes. The BalbC mice were immunised with the plant leaf expressed G-protein. Commercially available killed rabies virus vaccine served as positive control. Plant derived chimeric G protein elicited higher immune response as compared to the commercial vaccine. The mice displayed protective immunity when they were challenged with live virus.Chimeric G protein expressed at high level in plant leaves was demonstrated to function as a commercially valuable subunit vaccine against rabies virus infection. It is very valuable for rabies management in human, pets and wild life. Further, edible part of such transgenic plants or the purified protein may also be useful as oral vaccine.

The present invention relates to recombinant anti-rabies vaccines and the oral administration of such vaccines to skunks and/or mongooses. Advantageously, the antirabies vaccine may comprise a recombinant vaccinia virus containing a rabies glycoprotein gene. The invention encompasses methods of vaccinating skunks and/or mongooses by administration of an anti-rabies vaccines which may comprise a recombinant vaccinia virus containing a rabies glycoprotein gene.
摘要:
A method of inducing a CD8+ T response against a selected molecule by delivering the molecule via a recombinant simian adenovirus is provided. Also provided are methods of inducing interferon-α and interferon-β by delivering a recombinant simian adenovirus to a subject. The methods and compositions of the invention are particularly well suited for prophylaxis and treatment of infections with human immunodeficiency virus and human papilloma virus, among others, and cancer therapy.
摘要:
A cat vaccine formula including at least three polynucleotide vaccine valencies that each include a plasmid containing a cat pathogen valency gene capable of being expressed in vivo in host cells. Said valencies are selected from the group which consists of feline leukaemia virus, panleukopenia virus, infectious peritonitis virus, coryza virus, calicivirus disease virus, feline immunodeficiency virus and optionally rabies virus. Said plasmids include one or more genes per valency, and said genes are selected from the group which consists of env and gag for feline leukaemia, VP2 for panleukopenia, modified S, M and N for infectious peritonitis, gB and gD for coryza, capsid for calicivirus disease, env and gag/pro for feline immunodeficiency and G for rabies.
摘要:
A recombinant adenovirus acting as a vector for an antigen-producing gene (e.g. a rabies glycoprotein gene) comprises a CAV-2 strain modified to contain the promoter-gene sequence within the region from the SmaI site close to the end of the inverted terminal repeat up to the promoter for the early region 4 (E4). To assist replication the recombinant virus is transfected into a cell line expressing Ela proteins. The recombinant virus is used for the production of a corresponding vaccine.
摘要:
The present disclosure is directed towards chimeric glycoproteins wherein the clip region, a core region, a flap region, and a transmembrane and cytoplasmic domain are defined by starting from the amino terminus of the protein, these domains are comprised of the following amino acid residue ranges: clip, 1 through 40 to 60; core, 40 to 60 through 249 to 281; flap, 249 to 281 through 419 to 459; the transmembrane domain is comprised of amino acids 460 through 480, and the remaining amino acids 481 through 525 comprise the cytoplasmic domain.; and wherein the clip, core, flap, transmembrane, and cytoplasmic domain comprise a chimeric combination of at least two lyssavirus, wherein the chimeric glycoprotein is advantageously inserted into a rabies-based vaccine vector.

摘要:
The present invention relates to an mRNA sequence, comprising a coding region, encoding at least one antigenic peptide or protein of Rabies virus or a fragment, variant or derivative thereof. Additionally the present invention relates to a composition comprising a plurality of mRNA sequences comprising a coding region, encoding at least one antigenic peptide or protein of Rabies virus or a fragment, variant or derivative thereof. Furthermore it also discloses the use of the mRNA sequence or the composition comprising a plurality of mRNA sequences for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the prophylaxis or treatment of Rabies virus infections. The present invention further describes a method of treatment or prophylaxis of rabies using the mRNA sequence.
