  • 1

    The INSTALL system utilizes circular single-stranded DNA (cssDNA) to reduce immune responses during genome editing.

  • 2

    Traditional double-stranded DNA (dsDNA) templates activate immune sensors, limiting their use in genome editing.

  • 3

    INSTALL achieves high-fidelity DNA integration with improved efficiency and tolerability in human cells and mice.

  • 4

    Lipid nanoparticle delivery of cssDNA allows for systemic dosing and repeat administration without severe immune activation.

  • 5

    INSTALL combines immune-evasive nucleic acids with recombinase precision, enhancing non-viral in vivo genome writing.
