RNA DELIVERY VEHICLES

摘要

The present invention relates to double stranded nucleic acid (dsNA) delivery vehicles comprising a dsNA, and a clostridial endosomal translocation domain. Said delivery vehicle may further comprise a non-cytotoxic protease and/ or a Targeting Moiety (TM). The present invention also provides a method for delivering an RNA guide strand into a target cell, and to the use of a dsNA delivery vehicle for down-regulating mRNAactivity in a target cell. In one embodiment, the RNA guide strand binds to a SNARE mRNA target sequence, which leads to the suppression of SNARE protein expression in the target cell.
