Endosomal escape, and the potential for reducing inflammation in LNP-based therapies: a possibility that might become a reality sooner than expected
Despite their success of LNPs in the clinic, a significant hurdle remains: LNPs are associated with severe, sometimes exacerbated pre-existing inflammation, an unintended consequence which has prompted a deeper exploration into the mechanisms of LNP-induced inflammation and the pursuit of innovative solutions to mitigate these effects.
Through what I would call a "meticulous process of structure-function screening" of lipids and analyses of signaling pathways, a team of researchers have begun to unravel the complexities behind the inflammation caused by LNPs.
A key discovery is the dual role of the LNPs' ability to escape endosomes. While essential for effective RNA expression, this feature also directly triggers inflammation by damaging endosomal membranes. The large, irreparable holes created are recognized by cytosolic proteins known as galectins, which bind to sugars on the damaged endosomal membranes and catalyze downstream inflammatory responses.
Their research reveals two promising strategies to circumvent this inflammatory response:
1- Inhibiting galectins effectively abrogates LNP-associated inflammation, both in vitro and in vivo. This approach prevents the recognition of extensive endosomal damage, thus blocking the inflammatory cascade at its origin.
2- Secondly, the team has developed rapidly biodegradable ionizable lipids that create smaller, reparable holes in endosomes. These minor disruptions are manageable by the endosomal sorting complex required for transport (ESCRT) pathway, allowing for high mRNA expression without significant inflammatory reactions.
These findings not only enhance our understanding of LNP-induced inflammation but also offer viable paths forward. By either inhibiting galectin activity or employing biodegradable ionizable lipids, we can design LNPs that minimize inflammation while maintaining their efficacy in mRNA delivery. Both approaches have shown compatibility with therapeutic mRNAs that reduce inflammation in disease models, contrasting sharply with traditional LNPs that exacerbate inflammatory conditions.

Isolating the formation kinetics of peptide-based miRNA nanoparticles for better targeted nano therapeutics!
In the quest to harness the power of microRNA (miRNA) for cancer treatment, scientists face significant challenges, including the broad size distribution and poor long-term colloidal stability of miRNA-carrying nanoparticles. Indeed, these obstacles have delayed the clinical application of such nanoparticles, particularly those formed through polyelectrolyte complexation. However, a new study has set a new precedent.
Leveraging the art of peptide design and a "cutting-edge" technique known as optimized flash nanocomplexation (FNC), researchers have crafted uniform peptide-based miRNA particles that stand out for their exceptional stability and potent anticancer activity, both in vitro and in vivo. The secret to their success? The strategic modulation of lysine-based charge within small intrinsically disordered peptides, essential for complexing miRNA and achieving stable colloidal solutions.
FNC emerges as a game-changer, isolating kinetic steps in particle formation, thus allowing for the production of particles with discrete sizes in a manner that is not only highly reproducible but also scalable. This advancement paves the way for seamless pre-clinical studies and marks the first instance, to the authors' knowledge, of using FNC for preparing miRNA and peptide polyelectrolyte complexes.
The encapsulation of these particles within an injectable hydrogel matrix revolutionizes their in vivo delivery. A one-time syringe injection of a gel laden with particles composed of miRNA-215-5p and the peptide PKM1 significantly curtails tumor progression in a xenograft model of mesothelioma.
This study not only shows a clearer path toward overcoming longstanding barriers in miRNA therapeutic delivery but also exemplifies the potential of peptide-based nanoparticles in advancing cancer treatment.
