Abstract
The newly developed PFS formulation demonstrated successful expression of mRNA in both Raw 264.7 cells and Balb/c mice.
- PFS is a modified cationic polymer that enhances mRNA delivery through improved cellular uptake.
- The formulation utilizes sorbitol channels and caveolae-mediated endocytosis for effective delivery.
- Fluorination of the polymer aids in endosomal escape and reduces toxicity.
- Intramuscular administration of the SARS-CoV-2 spike mRNA vaccine produced immune responses comparable to Moderna's formulation.
- The vaccine effectively neutralized the Wuhan variant strain of SARS-CoV-2, as shown by PRNT testing.
- The findings indicate that PFS could be a promising candidate for developing mRNA vaccines for various diseases.
