Provided are compositions comprising an oligonucleotide that targets Thymic stromal lymphopoietin (TSLP). The oligonucleotide may include a small interfering RNA (siRNA) or an antisense oligonucleotide (ASO). Also provided herein are methods of treating an airway disorder by providing an oligonucleotide that targets TSLP to a subject in need thereof. In some embodiments, the oligonucleotide targeting is specific for a long isoform of TSLP (1fTSLP).

An siRNA conjugate having a structure as represented by formula (1) for inhibiting hepatitis B vims gene expression, comprising siRNA and a conjugated group, wherein the sense strand of the siRNA comprises a nucleotide sequence 1, and the antisense strand comprises a nucleotide sequence 2; the nucleotide sequence 1 and the nucleotide sequence 2 are, at least in part, reversely complementary to form a double-stranded region; the nucleotide sequence 1 and SEQ ID NO: 1 are equal in length and differ by no more than three nucleotides; the nucleotide sequence 2 and SEQ ID NO: 2 are equal in length and differ by no more than three nucleotides. The siRNA conjugate can specifically target liver cells and effectively solve the problem of siRNA delivery in vivo, and shows excellent activity and low toxicity to inhibit HBV gene expression while maintaining high stability of siRNA.

The present invention relates to RNAi agents, e.g., double stranded RNA (dsRNA) agents, targeting the SERPINF2 gene. The invention also relates to methods of using such RNAi agents to inhibit expression of a SERPINF2 gene and to methods of preventing and treating a SERPINF2-associated disorder, e.g., a disorder associated with thrombosis.

This disclosure relates to novel DGAT2 targeting sequences. Novel DGAT2 targeting oligonucleotides for the treatment of non-alcoholic fatty liver disease (NAFLD) and lipodystrophy syndromes (or metabolic syndrome) are also provided.

Described are RNA interference (RNAi) agents for treating a Hepatitis D Virus (HDV) infection in a subject in need thereof.

This invention relates to compounds, compositions, and methods useful for reducing α-1 antitrypsin target RNA and protein levels via use of dsRNAs, e.g., Dicer substrate siRNA (DsiRNA) agents.

The present invention relates to RNAi agents, e.g., dsRNA agents, targeting the coronavirus genome. The invention also relates to methods of using such RNAi agents to inhibit expression of a coronavirus genome and to methods of treating or preventing a coronavirus-associated disease in a subject.

Described are methods for inhibition of Hepatitis B virus gene expression or treating symptoms and/or diseases associated with Hepatitis B virus infection. Dosing regimens for administering these RNAi agents are also described. RNA interference (RNAi) agents for inhibiting the expression of Hepatitis B virus gene are described. The HBV RNAi agents disclosed herein may be targeted to cells, such as hepatocytes, for example, by using conjugated targeting ligands. Pharmaceutical compositions comprising one or more HBV RNAi agents optionally with one or more additional therapeutics are also described. Delivery of the described HBV RNAi agents to infected liver in vivo provides for inhibition of HBV gene expression and treatment of diseases and conditions associated with HBV infection.

RNAi agents for inhibiting the expression of the alpha-1 antitrypsin (AAT) gene, compositions including AAT RNAi agents, and methods of use are described. Also disclosed are pharmaceutical compositions including one or more AAT RNAi agents together with one or more excipients capable of delivering the RNAi agent(s) to a liver cell in vivo. Delivery of the AAT RNAi agent(s) to liver cells in vivo inhibits AAT gene expression and treats diseases associated with AAT deficiency such as chronic hepatitis, cirrhosis, hepatocellular carcinoma, transaminitis, cholestasis, fibrosis, and fulminant hepatic failure.

One aspect of the present invention relates to double-stranded RNA (dsRNA) agent capable of inhibiting the expression of a target gene. Other aspects of the invention relate to pharmaceutical compositions comprising these dsRNA molecules suitable for therapeutic use, and methods of inhibiting the expression of a target gene by administering these dsRNA molecules, e.g., for the treatment of various disease conditions.
