Abstract: Disclosed are new synthetic compounds that includes a lipid diether to which a sugar group is grafted via a PEG spacer, and to now liposomes including at least one of the compounds. In particular, new synthetic compounds of general formula (I) and to new liposomes including at least one of the compounds is disclosed, as well as new liposomes for use as vectors and/or adjuvants, especially for use in vaccines.

Abstract: The invention describes a device (10) for dispensing microbubbles (30) for cell sonoporation, comprising: a tube configured to receive a vial (20) containing a solution (26) of microbubbles (30), at least two catheters (11, 12) arranged inside the tube and opening into the vial (20) when the latter is received by the tube, wherein, when the first catheter (11) is connected to a first air injection source, air can be injected into the vial (20) via the first catheter so as to generate an overpressure therein, the microbubbles (30) contained in the vial (20) entering the second catheter (12) and moving toward its second end (122). The invention also relates to a sonoporation device, a sonoporation process and a computer program product.

Abstract: The application relates to the production of RNA of interest, more specifically of messenger RNA of interest or of long non-coding RNA of interest, by yeasts with recombinant pseudo-viral particles. The recombinant yeasts have been genetically modified in order to produce the RNA of interest in the form of a complex, particularly in the form of recombinant pseudo-viral particles. These recombinant pseudo-viral particles are produced from certain elements of yeast Ty retrotransposon, but do not retrotranscribe the RNA that they contain. Thus, the application relates to the components that are thus capable of being implemented or produced, and particularly to the nucleic acid constructs, kits, bacteria cells, yeast cells, culture or transfection media containing them, as well as to a method for producing a pharmaceutical composition, particularly for medical applications, more specifically for vaccines, anti-tumour and pro-regenerative applications.

Abstract: A method for the in vitro production of DNA minicircles includes steps of: a) providing nicked double-stranded oligodeoxynucleotides bunt-ended substrates having at least one phosphorylated 5? end, b) performing a ligase-mediated circularization on a reaction mixture including the nicked double-stranded oligodeoxynucleotides substrates and a DNA bending protein, and c) obtaining DNA minicircles.
