Building mouse models for a new SEND mRNA delivery system
Prototype Mouse Models for SEND-Based mRNA Delivery and Technology Development
This project is developing a natural cell-based way to carry therapeutic mRNA into target cells, with the goal of making gene and mRNA therapies safer and more effective for people with genetic diseases.

What this research studies
Researchers are creating and using mouse models to test a recently discovered system called SEND, which packages mRNA inside PEG10 protein particles that can move between cells. They will engineer PEG10 capsids and partner proteins (fusogens) to carry different therapeutic mRNAs and watch how well these particles get into target tissues in living animals. The team will compare designs to improve targeting, stability, and safety before any human use. Findings will guide whether SEND-based delivery could move into future human trials for gene or mRNA therapies.
Who could benefit from this research
Good fit: People with inherited or genetic diseases that might be treated by gene replacement or mRNA therapies are the eventual candidates who could benefit from future trials based on this technology.
Not a fit: Patients with conditions unrelated to gene or mRNA-based approaches, or those needing immediate therapy, are unlikely to benefit directly from this preclinical mouse-focused work.
Why it matters
Potential benefit: If successful, this work could lead to a safer, more precise way to deliver gene or mRNA treatments to patients with genetic disorders.
How similar studies have performed: Early laboratory studies and initial mouse experiments show SEND can package and transfer mRNA between cells, but human testing has not yet occurred and clinical benefit remains unproven.
