<p>Central to our <b>delivery system</b> is <b>AirBuddy</b>, a lung-specific lipid nanoparticle designed to stabilize and protect the prime editing complex during transport to lung epithelial cells. <b>AirBuddy</b> ensures that the protein complex is delivered specifically to lung cells, enhancing the efficiency of the gene-editing process. By modifying the lipid nanoparticle with protective features, we achieved increased stability, ensuring effective delivery to the target cells. </p>
<p>We further optimized the prime editing fusion protein, <b>PrimeGuide</b>, to streamline its components, resulting in a smaller and more efficient prime editing complex. This improvement significantly enhances the precision of the gene editing process, reducing off-target effects and increasing the overall success of mutation correction. </p>
<p>In subsequent experiments, <b>HEK and lung (CFBE41o-)cells</b> carrying the CFTR <i>F508del</i> mutation were successfully <b>transfected</b> with the optimized prime editing complex. Our results indicated successful correction of the mutation, confirming the potential of our approach for treating Cystic Fibrosis. </p>
<p>Additionally, we explored <b>downstream applications</b>. Primary cell cultures were treated with lipid nanoparticles to introduce a reporter RNA. We also established 2D cultures transfected with YFP, a sodium-sensitive reporter protein, to assess ion channel functionality. Finally, in CFTR-deficient organoids, our system facilitated repair of the CFTR channel, evidenced by an increase in organoid volume upon treatment. This suggests successful functional restoration of CFTR activity. </p>

<p>At <b>PreCyse</b>, we envision a future where gene therapy for Cystic Fibrosis (CF) is as simple and user-friendly as using an inhaler. Our goal is to develop a fully integrated Prime Editing system, <b>PrimeGuide</b>, delivered via a cutting-edge lipid nanoparticle (LNP) platform, <b>AirBuddy</b>. The therapy would allow patients to inhale the therapeutic complex, targeting the underlying genetic mutation that causes CF—specifically, the F508del mutation in the CFTR gene. </p>
