摘要:
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.

摘要:
A method and antisense compound for inhibiting the growth of pathogenic bacterial cells are disclosed. The compound contains no more than 12 nucleotide bases and has a targeting nucleic acid sequence of no fewer than 10 bases in length that is complementary to a target sequence containing or within 10 bases, in a downstream direction, of the translational start codon of a bacterial mRNA that encodes a bacterial protein essential for bacterial replication. The compound binds to a target mRNA with a Tm of between 50° to 60° C. The relatively short antisense compounds are substantially more active than conventional antisense compounds having a targeting base sequence of 15 or more bases.
摘要:
Improved methods are described for solid-phase synthesis of morpholino oligomers, in which a protected morpholino ring nitrogen is deprotected between coupling steps using a heterocyclic amine salt in a trifluoroethanol-containing solvent, where the salt is a salt of a heterocyclic amine, having a pKa in the range of 1-4 in its protonated form, with an acid selected from a sulfonic acid, trifluoroacetic acid, and hydrochloric acid. Examples are 3-chloropyridinium methanesulfonate (CPM) and 4-cyanopyridinium trifluoroacetate (CYTFA).
摘要:
An antisense compound for use in treating myotonic dystrophy DM1 or DM2, a method of enhancing antisense targeting to heart and quadricep muscles, and a method for treating DM1 or DM2 in a mammalian subject are disclosed. The oligonucleotide has 8-30 bases, with at least 8 contiguous bases being complementary to the polyCUG or polyCCUG repeats in the 3′UTR region of dystrophia myotonica protein kinase (DMPK) mRNA in DM1 or DM2, respectively. Conjugated to the oligonucleotide is a cell-penetrating peptide having the sequence (RXRR(B/X)R)2XB, where R is arginine; B is β-alanine; and each X is —C(O)—(CH2)n—NH—, where n is 4-6. The antisense compound is effective to selectively block the sequestration of muscleblind-like 1 protein (MBNL1) and/or CUGBP, in heart and quadricep muscle in a myotonic dystrophy animal model.
摘要:
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.

A method and compound for treating skeletal muscle mass deficiency in a human subject are disclosed. The composition is an oligomer of morpholino subunits and phosphorus-containing intersubunit linkages joining a morpholino nitrogen of one subunit to a 5′ exocyclic carbon of an adjacent subunit, contains between 10-40 nucleotide bases, has a base sequence effective to hybridize to an expression-sensitive region of processed or preprocessed human myostatin RNA transcript, identified, in its processed form, by SEQ ID NO:6, and is capable of uptake by target muscle cells in the subject. In practicing the method, the compound is administered in an amount and at a dosage schedule to produce an overall reduction in the level of serum myostatin measured in the patient, and preferably to bring the myostatin level within the a range determined for normal, healthy individuals.
