Abstract: The present invention provides a vector system comprising a mutated post-transcriptional regulatory element. In particular, the present invention relates to a mutated WPRE sequence that can efficiently express nucleotides of interest in a retroviral vector system. The present invention also relates to methods of delivering and expressing nucleotides of interest to a target cell.

Abstract: The present invention provides a vector system comprising a nucleotide sequence coding for an antibody. In particular, the present invention relates to the use of such a vector system in a subject, where the nucleotide sequence is expressed in vivo to produce said antibody.

Abstract: The invention relates to the exploitation of the migratory behaviour of mononuclear phagocytes with a view to targeting therapeutic drug delivery. The invention therefore concerns the attachment or incorporation of a therapeutic agent to or into a mononuclear phagocyte and the subsequent migration of the mononuclear phagocyte to a target area.

Abstract: The present invention provides 5T4 tumour-associated antigen (TAA) for use in a method of immunotherapy of tumours. The invention also relates to a recombinant poxvirus vector from which at least one immune evasion gene has been deleted, which comprises a nucleic acid sequence encoding a 5T4 TAA and the use thereof in vaccinating against and in treating tumours.

Abstract: The present invention relates to a retroviral vector system comprising a therapeutic gene wherein said retroviral vector system is pseudotyped with at least part of a heterologous envelope protein or a mutant, variant or homologue thereof and wherein said therapeutic gene is downstream of an internal promoter.

Abstract: A retroviral vector is described. The retroviral vector comprises a functional splice donor site and a functional splice acceptor site; wherein the functional splice donor site and the functional splice acceptor site flank a first nucleotide sequence of interest (“NOI”); wherein the functional splice donor site is upstream of the functional splice acceptor site; wherein the retroviral vector is derived from a retroviral pro-vector; wherein the retroviral pro-vector comprises a first nucleotide sequence (“NS”) capable of yielding the functional splice donor site and a second NS capable of yielding the functional splice acceptor site; wherein the first NS is downstream of the second NS; such that the retroviral vector is formed as a result of reverse transcription of the retroviral pro-vector.

Abstract: The use of an ScFv Ab (ScFv Ab) capable of recognising a disease associated molecule (DAM) in the manufacture of a medicament for the prevention and/or treatment of a disease condition associated with a DAM is described. The ScFv Ab has therapeutic, diagnostic and prognostic applications.

Abstract: Retroviral vector production systems for producing lentivirus-based vector particles which are capable of infecting and transducing non-dividing target cells, wherein one or more of the auxiliary genes such as vpr, vif, tat, and nef in the case of HIV-1 are absent from the system. The systems and resulting retrovirus vector particles have improved safety over existing systems and vectors.

Abstract: The invention relates to the exploitation of the migratory behavior of mononuclear phagocytes with a view to targeting therapeutic drug delivery. The invention therefore concerns the attachment or incorporation of a therapeutic agent to or into a mononuclear phagocyte and the subsequent migration of the munonuclear phagocyte to a target area.

Abstract: A method for producing viral vectors is described using packaging and producer cell lines is described. The producer cell comprises: (i) a first nucleotide sequence (NS) encoding a toxic viral envelope protein operably linked to a promoter; wherein the promoter is operably linked to at least one copy of a TRE; (ii) a second NS wherein the second NS comprises a sequence encoding a tetracycline modulator; (iii) a third NS encoding a retrovirus nucleocapsid protein; and (iv) a fourth NS comprising a retroviral sequence capable of being encapsidated in the nucleocapsid protein such that the retroviral vector particle titre obtainable from the producer cell is regulatable by tetracycline and an initial stimulus with sodium butyrate or functional analogues thereof.
