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.

The antisense antiviral compounds have morpholino subunits linked by uncharged phosphorodiamidate linkages interspersed with cationic phosphorodiamidate linkages. An exemplary embodiment of the invention provides an antisense compound directed to the HIV Vif gene, causing the production of defective HIV- 1 virions in an infected individual.

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 an expression-sensitive region of a preprocessed or processed human CD86 transcript identified, in its processed form, by SEQ ID NO:33, to form a duplex structure between said compound and transcript having a Tm of at least 45° C. Formation of the duplex blocks expression of full-length CD86 in said 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 therapeutic oligomer-peptide conjugate, and methods of using the conjugate are disclosed. The conjugate includes (a) a substantially uncharged oligonucleotide analog compound having a base sequence that includes a string of bases that are complementary to four or more contiguous cytosine bases in a target nucleic acid region to which the compound is intended to bind, and (b) conjugated to the compound, an arginine-rich peptide effective to enhance the uptake of the compound into target cells. The string of bases in the compound includes at least one inosine base positioned in the string so as to limit the number of contiguous guanine bases in said string to three or fewer. The conjugate has greater cellular uptake than the compound alone, by virtue of the arginine-rich peptide, and substantially greater antisense activity greater activity than the conjugate in the absence of inosine-for guanine substitutions.
