Targeted-Penetrating Biomimetic Hybrid Transfersomes for Enhanced Transdermal Gene Transfection in Hypertrophic Scar Therapy.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hypertrophic scar (HS) is a recurrent and inflammatory dermal fibrotic disorder, characterized by abnormal fibroblast proliferation and excessive extracellular matrix (ECM) deposition. Affecting over 310 million patients worldwide, while effective strategies to halt progression remain lacking. The TGF-β-mediated fibrotic cascade is the central driver of HS, and siRNA-based therapeutics offer a promising gene-level intervention owing to their high sequence specificity and low off-target risk. However, siRNA translation is limited by rapid degradation, poor transfection, insufficient targeting, and the dense scar barrier that restricts noninvasive delivery. Proteomic analysis revealed that hypertrophic scar fibroblasts (HSFs) exhibit enhanced bioadhesion and protein-binding functions, with Thy-1 membrane glycoprotein highly and specifically expressed, providing a target for HSFs-active delivery. We hybridized HSFs membranes with cationic transfersomes using ultrasonic co-extrusion and achieved efficient loading of TGF-β1 siRNA through electrostatic self-assembly. This membrane-hybridized platform enabled multipathway transdermal delivery of siRNA via intercellular transport, transcytosis, and skin appendageal routes, while improving transfection, immune evasion, and homotypic targeting. Studies demonstrated efficient silencing of TGF-β1, suppression of α-SMA, ECM deposition, and pro-inflammatory cytokine release, thereby mitigating fibrotic progression. The system provides an innovative strategy for transdermal targeted siRNA therapy of HS and other skin diseases requiring genetic intervention.
