Abstract

Gene therapies and cell therapies require precise, reversible and patient-friendly control over the production of therapeutic proteins. Here we present a fully human nitric-oxide-responsive gene-regulation system for the on-demand and localized release of therapeutic proteins through clinically licensed nitroglycerin patches. Designed for simplicity and robust human compatibility, the system incorporates human mitochondrial aldehyde dehydrogenase for converting nitroglycerin into nitric oxide, which then activates soluble guanylate cyclase to produce cyclic guanosine monophosphate, followed by protein kinase G to amplify the signal and to trigger target gene expression. In a proof-of-concept study, human cells expressing the nitroglycerin-responsive system were encapsulated and implanted subcutaneously in obese mice with type 2 diabetes. Transdermal nitroglycerin patches applied over the implant enabled the controlled and reversible production of glucagon-like peptide-1 throughout the 35-day experimental period, effectively restoring blood glucose levels in these mice without affecting heart rate or blood pressure. The approach may facilitate the development of safe, convenient and responsive implantable devices for the sustained delivery of biopharmaceuticals for the management of chronic diseases.

期刊介绍： Nature Biomedical Engineering is an online-only monthly journal that was launched in January 2017. It aims to publish original research, reviews, and commentary focusing on applied biomedicine and health technology. The journal targets a diverse audience, including life scientists who are involved in developing experimental or computational systems and methods to enhance our understanding of human physiology. It also covers biomedical researchers and engineers who are engaged in designing or optimizing therapies, assays, devices, or procedures for diagnosing or treating diseases. Additionally, clinicians, who make use of research outputs to evaluate patient health or administer therapy in various clinical settings and healthcare contexts, are also part of the target audience.
