The present invention relates to recombinantly constructed proteins useful for analytical assays, in particular for determining in a biological sample obtained from an individual the presence of antibodies specific for a rhabdovirus. More particular, the present invention relates to a polypeptide comprising an ectodomain of a rhabdovirus glycoprotein and a heterologous multimerization domain linked to said ectodomain. In one example, a fusion protein of the formula x-y-z is provided, wherein x consists of or comprises such an ectodomain being optionally free of a furin cleavage site, y is a linker moiety, and z is a heterologous multimerization domain optionally selected from the group consisting of immunoglobulin sequence, coiled coil sequence, streptavidin sequence, fibritin sequence, and avidin sequence.

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.

The present invention relates to a recombinant plasma membrane-based vesicle, and more specifically to a recombinant plasma membrane-based vesicle comprising a VSV-G mutated protein in which histidine, the 162.sup.nd amino acid, has been substituted with arginine, and a pharmaceutical composition for treating cancer comprising the recombinant plasma membrane-based vesicle.

The present disclosure concerns an oncolytic virus for the treatment of cancer, such as in brain cancer, for example glioblastoma. The oncolytic virus may exhibit reduced levels of neurotoxicity. The oncolytic virus may be an isolated viral particle capable of producing a cDNA polynucleotide that includes a sequence according to SEQ ID NO: 1 when the virus is in a host cell. The oncolytic virus may be an isolated viral particle that includes an RNA polynuclotide that includes a sequence according to SEQ ID NO: 2. The oncolytic virus may be an isolated viral particle having a genome that includes open reading frames that encode: proteins having sequences comprising SEQ ID NOs: 3, 4, 5, 6 and 7; or variants thereof.

The present invention belongs to the field of compliance markers and marker vaccines which allow for the differentiation between infected and vaccinated individuals. In particular, it relates to a method of determining whether an individual has received an immunogenic composition comprising a recombinant protein produced by a baculovirus expression system in cultured insect cells.

Provided for herein are viral particles comprising a heterologous viral glycoprotein and a targeting moiety, wherein the targeting moiety comprises a polypeptide comprising a formula of T-S.sub.1, wherein T is a target binding domain and S.sub.1 is a stalk portion. The stalk portion may comprise a variant Fe domain. The stalk portion may comprise a flexible polypeptide domain. The targeting moiety comprising the formula T-S.sub.1 may be incorporated into a viral particle to assist with targeting such particles to a specific cell type. Also provided for herein are compositions comprising the same, and methods of using the same.

The disclosure provides artificial viral compositions for use in treating cancer or a hyperproliferative disorder in a subject to whom the compositions are administered, as well as to methods of making and using the compositions.
