Abstract: The present invention pertains to a new nanoparticle-like delivery system for intracellular delivery of cargo molecules such as nucleic acids, ribonucleoproteins and extracellular vesicles.

Abstract: The present invention relates to a system for intracellular delivery of a cargo comprising at least one component A chosen from aliphatic linear or branched moieties with at least 4 carbon atoms and/or cyclic ring systems comprising 2-4 rings which may contain several hetero atoms chosen from N, S, O and P, wherein component(s) A is (are) attached to a cell penetrating peptide B and/or a non-peptide analogue thereof. It also relates to methods of using the system in diagnosis of diseases, as research tool and as a targeting system, a composition comprising the system and especially a pharmaceutical composition a material covered with the system and a material having the delivery systems into the material. Finally it relates to novel peptides.

Abstract: Viral vectors are potential tools for eliminating the viability of eukaryotic cells in anti-cancer therapies since they can efficiently destroy the cancer cells and trigger an immune response against tumours. Typically viruses are not specific to cancer cells and all methods known in art aiming to the construction of cancer-specific viruses suffer from serious problems. The present invention presents a universal method to overcome these problems and is usable for any DNA virus replicating in nucleus or for any layered vector of RNA viruses. In this method the viral gene expression and/or replication will be blocked by the introduction of one or more aberrantly spliced introns into crucial gene expression units of the virus or vector. Lethal effect of these mutations is reverted in a controlled manner by the delivery of splice-switch oligonucleotide (s) correcting the introduced defects and restoring the biological functionality of the virus or vector, including cytolytic properties.
