  • Publication number: 20230272342
    Abstract: The present invention relates to regulatory T cell and uses thereof. By their immunosuppressive and anti-inflammatory activities, regulatory T cells play a central role in peripheral tolerance and thus critically prevent the development of autoimmune and inflammatory disorders. The inventors showed that Foxp3+CD4+ Tregs express high levels of LT?, which negatively regulates their immunosuppressive signature. They demonstrated that the adoptive transfer of LT??/? Tregs in mice protects from dextran sodium sulfate (DSS)-induced colitis and attenuates inflammatory bowel disease (IBD), multi-organ autoimmunity and the development of CAC. The inventors also showed that by mixed bone marrow chimeras that LT? expression specifically in hematopoietic cells negatively controls the immunosuppressive signature of Tregs. In particular, the present invention relates to regulatory T cell characterized in that it does not express or expresses reduced levels of lymphotoxin alpha.

  • Publication number: 20230272385
    Abstract: The present invention relates to nucleic acids for inhibiting expression of a target gene in a cell, comprising at least one duplex region that comprises at least a portion of a first strand and at least a portion of a second strand that is at least partially complementary to the first strand, wherein said first strand is at least partially complementary to at least a portion of RNA transcribed from said target gene to be inhibited. The first strand of the nucleic acid has a terminal 5?(E)-vinylphosphonate nucleotide that is linked to the second nucleotide in the first strand by a phosphodiester linkage.

  • Publication number: 20230272387
    Abstract: Provided herein are methods for increasing levels of SCN2A protein in a cell, comprising contacting the cell with an antisense oligonucleotide that enhances splicing at a splice site of a retained intron in an intron-retaining SCN2A mRNA or pre-mRNA, wherein the retained intron is selected from among intron 1, 2, 3, 4, 5, 11, 13, 17 and 24 and wherein the antisense oligonucleotide comprises a sequence of nucleobases that is complementary to a target region in the SCN2A mRNA or pre-mRNA. Also provided are antisense oligonucleotides for use in such methods. Also provided are methods for treating disorders associated with a heterozygous loss-of-function mutation in SCN2A, comprising administering to the subject such antisense oligonucleotides.

  • Publication number: 20230272389
    Abstract: The present invention relates to miRNA interference technology. More specifically the invention relates to circular miRNA sponges that carry a plurality of binding sites directed to at least two types of miRNA and separated by random, non-identical spacers, allowing for the inhibition of functional classes of m1RNAs. Preferably, the binding sites are bulged binding sites wherein each bulge is created by a one base deletion and two base mismatch at positions 9-11 nt from the 3? end of each binding site. Preferably, each spacer is 6 to 24 nucleotides in length. Preferably, the binding sites are against miR-132 and miR-212, miR-17-5p and miR-18a-5p, or miR-20b-5p and miR-106a-5p. Construction vectors and uses of said miRNA sponges for the treatment of diseases, such as cardiomyopathy and cancer, are also disclosed.
