摘要:
The present invention relates to compositions comprising one or more active agents that selectively modulate the expression of two or more genes, for example at the post-transcription level, that are involved in fibrosis and/or inflammatory conditions. Also provided are methods of using such compositions for treating fibrotic diseases, as well as other diseases including inflammatory diseases and cancer.
摘要:
The present application provides peptides and nucleic acids that are useful for treating virus (e.g., SARS-CoV-2) infection. Exemplary peptides comprise chimeric peptides and blocking peptides that block the interaction between SPIKE and ACE2. Exemplary nucleic acids include siRNAs that specifically target SARS-CoV-2. The present applications also provide complexes and nanoparticles further comprising a second peptide (e.g., a cell-penetrating peptide) that promotes intracellular delivery of the peptides and nucleic acids.
