<H4 text="Size impact of pulmonary LNPs" id="text" />
In the context of pulmonary delivery, where the goal is to target the lungs, the size and properties of the LNPs are crucial. Particles smaller than 2 micrometers are particularly effective for reaching the alveolar regions of the lungs [11].
<H4 text="Role of surface modifications in targeting" id="text" />
<p>LNPs are pivotal not only for shielding mRNA but also for ensuring its efficient delivery into target cells. They facilitate cellular uptake through endocytosis, where the cell membrane engulfs the nanoparticle. LNPs are acclaimed for their high drug-loading capacities, which greatly enhance their therapeutic effectiveness. However, the success of this delivery hinges on effective endosomal escape. Ideally, LNPs release their mRNA payload into the cytoplasm after escaping from endosomes. If this escape process is inefficient, the mRNA can be degraded by lysosomes, which poses a significant challenge for mRNA vaccines and therapies [4].</p>
<p>A crucial advancement in LNP technology involves the use of pH-sensitive cationizable lipids. These lipids remain neutral at physiological pH but become cationic in the acidic environment of endosomes. This shift in charge helps dissociate the nanoparticles and disrupt the endosomal membrane, enhancing the likelihood of successful endosomal escape [5]. </p>
<p>Moreover, the surface of LNPs can be customized to improve targeting. For instance, incorporating specific lipids or modifying the surface with charged groups can direct the delivery of mRNA to targeted organs like the lungs or spleen [6]. Additionally, LNPs can be engineered with targeting ligands or antibodies to precisely direct their payload to specific cell types, further enhancing their therapeutic efficacy [7]. Another approach can be chitosan-based nanoparticles have been explored for their ability to adhere to mucus and enhance drug delivery through the respiratory tract. These nanoparticles can penetrate through the mucus layer to reach the lung tissues more effectively [8]. This versatility in design is essential for optimizing the delivery and effectiveness of LNP-based therapies.</p>

<p>We optimized lipid nanoparticles (LNPs) as a robust delivery system to transport larger therapeutic cargo, such as Prime Editing mRNA, to lung epithelial cells via inhalation. LNPs were chosen over other delivery systems, like Adeno-associated viruses (AAVs), due to their superior cargo capacity and reduced immunogenicity. Our goal is to create a lung-specific LNP, named AirBuddy, capable of efficiently delivering of our Prime Editing components, referred to as PrimeGuide, to lung tissues through inhalation. This approach is designed to advance precision medicine by ensuring targeted delivery with minimal off-target effects.</p>
