The paper details a scientific study published in Cell Reports Medicine regarding a novel gene therapy designed to treat pulmonary fibrosis. Researchers developed a targeted DNA triplex-forming oligonucleotide (TFO) liposome, known as tLipo-TFO1, which specifically targets fibrotic lung cells using an isoDGR peptide that binds to $\alpha$v$\beta$6 integrin receptors. By forming a DNA triplex at the Serpine1 gene site, this therapy effectively suppresses the production of plasminogen activator inhibitor 1 (PAI-1). Reducing PAI-1 levels activates the fibrinolytic system, which promotes the…
