20090012280OLIGONUCLEOTIDE COMPOUND AND METHOD FOR TREATING NIDOVIRUS INFECTIONS - A method and oligonucleotide compound for inhibiting replication of a nidovirus in virus-infected animal cells are disclosed. The compound (i) has a nuclease-resistant backbone, (ii) is capable of uptake by the infected cells, (iii) contains between 8-25 nucleotide bases, and (iv) has a sequence capable of disrupting base pairing between the transcriptional regulatory sequences in the 5′ leader region of the positive-strand viral genome and negative-strand 3′ subgenomic region. In practicing the method, infected cells are exposed to the compound in an amount effective to inhibit viral replication.01-08-2009
20090088562Oligonucleotide analogs having cationic intersubunit linkages - Morpholino oligomers containing both uncharged and cationic intersubunit linkages are provided. The oligomers are oligonucleotide analogs containing predetermined sequences of base-pairing moieties. The presence of the cationic intersubunit linkages in the oligomers, typically at a level of about 10-50% of total linkages, provides enhanced antisense activity, in various antisense applications, relative to the corresponding uncharged oligomers. Also provided are such oligomers conjugated to peptide transporter moieties, where the transporters are preferably composed of arginine subunits, or arginine dimers, alternating with neutral amino acid subunits.04-02-2009
20090110689IMMUNOSUPPRESSION COMPOUND AND TREATMENT METHOD - 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-4.04-30-2009
