Abstract: The present invention is in the field of oncolytic viruses. The invention provides new poxviruses which are engineered to be defective for the function encoded by the M2L locus (i.e., m2 function). Such poxviruses lack a functional m2 binding activity to at least one or both of CD80 and CD86 co-stimulatory antigens. Said oncolytic poxviruses are preferably vaccinia virus having a total or partial deletion of the M2L locus. The present invention also relates to cells and compositions comprising such poxviruses and their use for treating proliferative diseases such as cancers and for preventing diseases (vaccination, especially in veterinary field). More precisely, the invention provides an alternative to the existing oncolytic viruses which are largely used in virotherapy. The m2-defective poxviruses are particularly useful for the expression of immunomodulatory polypeptides such as anti-CTLA-4 antibodies with the purposes of stimulating or improve immune response.

Abstract: Described are novel anti-CTLA-4 antibody molecules and nucleotide sequences and expression vectors, such as viruses, encoding such antibody molecules. The novel antibody molecules are Treg depleting antibody molecules, and they have an improved depleting effect on CTLA-4 positive cells, such as Tregs, compared to ipilimumab. Described is also the use of such antibody molecules or nucleotide sequences or viruses in medicine, such as in the treatment of cancer, such as solid tumours.

Abstract: The present invention relates generally to novel immunogenic combinations comprising or encoding at least two heterooligomeric mycobacterial antigens and preferably a fusion polypeptide comprising said two heterooligomeric mycobacterial antigens, where the mycobacterial antigens are selected from the group of Esx, PE and PPE antigens of a Mycobacterium species, particularly a Mycobacterium of the tuberculosis complex such as Mycobacterium tuberculosis (Mtb). The present invention also relates to vectors, host cells and compositions comprising or encoding said immunogenic combination as well as to methods for expressing and producing it. The present invention also relates to methods of using said immunogenic combination, fusion polypeptide, vector, host cell, composition particularly for inducing or stimulating an immune response with the goal of providing a protective response against a Mycobacterium infection or any disease caused by or associated with a Mycobacterium infection.
