Accelerating Oral Wound Healing Using Bilayer Biomaterial Delivery of FTY720 Immunotherapy.
Article in Advanced healthcare materials, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Orofacial clefts are the most common congenital craniofacial anomaly. Adverse healing following cleft palate repair can lead to oronasal fistula (ONF), a persistent connection between the oral and nasal cavities. Although human allograft tissues are currently the gold standard for ONF repair, these methods carry risks of infection and rejection, often requiring surgical revision. Immunoregenerative therapies present a novel alternative approach to harness the body's immune response and enhance the wound healing environment. An FDA-approved immunomodulatory drug, FTY720, is repurposed to reduce lymphocyte egress and induce immune cell fate switching toward pro-regenerative phenotypes. In this study, a bilayer biomaterial system is engineered using Tegaderm to secure and control the delivery of FTY720-nanofiber scaffolds (FTY720-NF). The release kinetics of the bilayer FTY720-NF is optimized to maintain drug release for up to 7 days, ensuring safe transdermal absorption and tissue biodistribution. The comprehensive immunophenotyping results demonstrate a regenerative state transition in hybrid immune cells recruited to the wound site. Further, histological evaluations reveal a significant ONF closure in mice by day 7 following bilayer FTY720-NF implantation. These findings demonstrate the utility of immunomodulatory strategies for oral wound healing, better positing the field to develop more efficacious treatment options in pediatric patients.
