  • Publication number: 20180355372
    Abstract: An expression vector containing appropriate mitochondrion-targeting sequences (MTS) and appropriate 3?UTR sequences provides efficient and stable delivery of a mRNA encoding a protein (CDS) to the mitochondrion of a mammalian cell. The MTS and 3?UTR sequences guide the CDS mRNA from the nuclear compartment of the cell to mitochondrion-bound polysomes, where the CDS is translated. This provides an efficient translocation of a mature functional protein into the mitochondria. A method of targeting mRNA expressed in the nuclear compartment of a mammalian cell to the mitochondrion is also provided. The vector and methods can be used to treat defects in mitochondrial function.

  • Patent number: 10154235
    Abstract: A device for displaying an image sequence in the form of a pixel matrix, includes a control unit coupled to a projector. The control unit includes an input interface designed to receive asynchronous information representing, for each pixel of the matrix, events concerning the pixel, and a processor designed to control the activation of each pixel of the matrix at moments determined by the respective events indicated by the asynchronous information for the pixel. The projector is disposed on a support so as to illuminate the light receptors of the eye when the device is in use and is designed to project a light flux corresponding to the pixels activated by the control unit.
