The invention relates to a genetically modified infectious measles virus derived from a live-attenuated measles virus strain, in which the gene encoding the viral accessory C protein has been knocked out (MV-deltaC). It concerns in particular the use of said genetically modified infectious MV-deltaC in the treatment of malignant tumor or cancer conditions, and for the preparation of agents or compositions for such treatment.

The present invention relates to a recombinant virus of the family Paramyxoviridae, comprising at least one expressible polynucleotide encoding a multispecific binding polypeptide, said multispecific binding polypeptide comprising a first binding domain binding to a surface molecule of an immune cell with antitumor activity, preferably a lymphocyte, more preferably a T cell or a dendritic cell, and a second binding domain binding to a tumor-associated antigen; to a polynucleotide encoding the same, and to a kit comprising the same. Moreover, the present invention relates to a method for treating cancer in a subject afflicted with cancer, comprising contacting said subject with a recombinant virus of the family Paramyxoviridae of the invention, and thereby, treating cancer in a subject afflicted with cancer.

Provided is an adjuvant composition comprising a nucleic acid comprising a double-stranded RNA bound to a single-stranded DNA, the double-stranded RNA consisting of a nucleotide sequence of SEQ ID NO: 1 and its complementary sequence, the single-stranded DNA consisting of a nucleotide sequence of SEQ ID NO: 2. Also provided is a vaccine composition comprising the adjuvant composition and an antigen or an antigen component. The nucleic acid contained in the adjuvant composition is a chemically synthesizable nucleic acid having potent adjuvant activity and high safety.

Engineered fusion proteins comprising a self-excising degron for controlling protein production are disclosed. In particular, the inventors have constructed fusion proteins comprising a degron connected to a protein of interest through a cleavable linker comprising a hepatitis C virus (HCV) protease site. The degron can be removed from the protein of interest by a czs-encoded HCV protease such that the protein of interest can be produced with minimal structural modification. Clinically available HCV protease inhibitors can be used to block protease cleavage such that the degron is retained after inhibitor addition on subsequently synthesized protein copies. The degron when attached causes rapid degradation of the linked protein. Such fusions of a degron to a protein of interest will be especially useful when control over protein production with minimal structural modification is desired.

The use of targeting knottin polypeptides provides a means of selectively infecting target cells presenting species bound by the knottins. The targeted viruses may be used as cytotoxic agents, for example, as oncolytic viral therapeutics. Alternatively, the knottin-targeted viruses may be used to transform target cells in a gene therapy or immunotherapy context. An effective retargeted measles virus directed to integrins is demonstrated.
