  • Patent number: 9487786
    Abstract: A method and compound for suppressing an immune response in a mammalian subject, for the treatment or prevention of an autoimmune condition or transplantation rejection are disclosed. The compound is an antisense oligonucleotide analog compound having a targeting sequence complementary to a preprocessed CTLA-4 mRNA region identified by SEQ ID NO: 22 in SEQ ID NO: 1, spanning the splice junction between intron 1 and exon 2 of the preprocessed mRNA of the subject. The compound is effective, when administered to a subject, to form within host cells, a heteroduplex structure (i) composed of the preprocessed CTLA-4 mRNA and the oligonucleotide compound, (ii) characterized by a Tm of dissociation of at least 45° C., and (iii) resulting in an increased ratio of processed mRNA encoding ligand-independent CTLA-4 to processed mRNA encoding full-length CTLA-4.

  • Patent number: 8415313
    Abstract: A method and composition for inducing human dendritic cells to a condition of reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10 is disclosed. A population of dendritic cells is exposed to a substantially uncharged antisense compound, including partially positively charged, containing 12-40 subunits and a base sequence effective to hybridize to a target region within the sequence identified by SEQ ID NO:9, to form a duplex structure between the compound and transcript having a Tm of at least 45° C. Formation of the duplex blocks expression of full-length CD86 in the cells, which in turn leads to reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10.

  • Publication number: 20120027791
    Abstract: A method and conjugate for selectively killing antigen-activated T cells are disclosed. The conjugate is composed of a substantially uncharged antisense compound targeted against the human cFLIP protein, and a reverse TAT (rTAT) polypeptide coupled covalently to the antisense compound. The rTAT polypeptide is effective to produce selective uptake of the conjugate into antigen-activated T cells, relative to the uptake of the conjugate into non-activated T cells. The cFLIP antisense compound causes activation induced cell death (AICD) of activated lymphocytes. The method is useful in treating transplantation rejection and autoimmune conditions.

  • Publication number: 20110318382
    Abstract: An antisense oligonucleotide compound, composition, vaccine and methods for treating a variety of conditions characterized by up-regulation of IL-10 in a mammalian subject are disclosed. The compound (i) is composed of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5? exocyclic carbon of an adjacent subunit, (ii) is capable of uptake by monocytes, lymphocytes, and dendritic cells in a mammalian subject, (iii) contains between 10-40 nucleotide bases, and (iv) has a base sequence effective to hybridize to at least 12 contiguous bases of a target sequence contained in an exon-2 or exon-4 slice site region of human IL-10 pre-mRNA.
