Zip14-AAV Genetic MRI Reporter System for Non-Invasive Cell & Gene-Therapy Tracking
This technology includes a gene-based magnetic resonance imaging (MRI) reporter platform that harnesses adeno-associated virus (AAV) delivery of the metal transporter Zip14 to create image contrast wherever the gene is expressed. By driving Zip14 from cell-specific promoters, investigators obtain robust, long-lasting signal changes on standard clinical MRI sequences (e.g., MPRAGE and GRE), enabling real-time visualization of living cells and their gene-expression patterns. Because no external contrast agents, exotic pulse sequences, or tissue implantation steps are required, the system simplifies longitudinal studies and reduces safety concerns. The modular design supports rapid retargeting to other tissues, providing a scalable solution for tracking gene-therapy vectors, regenerative processes, or engineered cell therapies. Overall, Zip14-AAV reporters bridge the gap between molecular biology and routine radiology, opening a clear path toward clinically translatable, image-guided therapeutics.
- Non-invasive validation and dose-finding for AAV-mediated gene therapies in pre-clinical and early-phase clinical trials.
- Live mapping of neural-circuit plasticity, neuroregeneration, and brain-injury recovery in central-nervous-system (CNS) research.
- Longitudinal tracking of engineered cell therapies (e.g., CAR-T, stem cells) or oncolytic viruses without radioactive or optical labels.
- Contrast-agent free: generates MRI signal intrinsically through Zip14 expression, eliminating the cost, toxicity, and regulatory hurdles of injectable agents.
- Plug-and-play with existing scanners: produces high-contrast images on widely used MRI sequences, avoiding specialized hardware or pulse-sequence development.
- Promoter-based specificity: interchangeable promoters let users target neurons, glia, or peripheral cell types for precise, longitudinal monitoring across disease models.
