Imagine a future where cancer treatments are more effective and easier to access. That future might be closer than you think, thanks to groundbreaking research from Purdue University. Their innovative approach to delivering messenger RNA (mRNA) therapies for bladder cancer is making waves, and here's why you should care.
This isn't just another medical breakthrough; it's a game-changer. Purdue researchers have developed a patent-pending, virus-mimicking platform technology that surpasses traditional methods. The study, published in the prestigious Proceedings of the National Academy of Sciences, highlights the impressive capabilities of this new delivery system. We're talking about improvements in size, targetability, encapsulation efficiency, complex stability, gene expression, and even 'green' manufacturability.
So, what's the secret sauce? The team, led by Professor David Thompson from the James Tarpo Jr. and Margaret Tarpo Department of Chemistry and a member of the Purdue Institute for Cancer Research and the Purdue Institute for Drug Discovery, has been working on a layer-by-layer elastin-like polypeptide nucleic acid nanoparticle (LENN). Saloni Darji, a commercialization postdoctoral research associate, is the lead author of the paper.
Professor Thompson explains that the LENN system can be freeze-dried and stored as a powder for several days, retaining its full biological activity after rehydration. This is a huge deal because it addresses a major hurdle in current mRNA therapies. But here's where it gets controversial... Traditional lipid nanoparticle delivery systems need to be stored as liquids at temperatures below minus 45 degrees Celsius to maintain their effectiveness. LENN bypasses this need, offering a shelf-stable solution.
"We also confirmed that this biomanufacturable system homes to the target tissue and neither alters the natural entry pathway to those tumors nor triggers an immune response," Thompson stated. LENN delivers the mRNA directly into the cancer cells, leading to the expression of the protein encoded by the mRNA. And this is the part most people miss... The components of the LENN system are products of biological expression, making the delivery system readily manufacturable.
This technology has been disclosed to the Purdue Innovates Office of Technology Commercialization.
