🎓 Scientific Highlight of the Week 🎓 We are delighted to share insights from a brand-new study entitled "Modeling memory B cell responses in a lymphoid organ-chip to evaluate mRNA vaccine boosting" published in J. Exp. Med by Raphaël Jeger-Madiot et al: https://lnkd.in/dydxf_Rw Congratulations to all authors for this impressive study. They developed a lymphoid organ-chip (LO chip) model to predict the immunogenicity of candidate vaccines and demonstrated that the LO chip represents a versatile platform suited to the preclinical evaluation of vaccine-boosting strategies. Our LNP formulations engineered with a “Moderna-like” lipid composition and encapsulating mRNA encoding for GFP ad Ovalbumine were used as controls.

💉 How does LNP size affect vaccine performance? 👩🔬 In "Impact of lipid nanoparticle size on mRNA vaccine immunogenicity”, Kimberly Hassett and colleagues from the Moderna team took a systematic approach to modifying the particle size of #mRNA-#LNPs #vaccine formulations encoding for a cytomegalovirus surface pentamer complex and for envelope glycoprotein gB by adjusting formulation process variables while keeping lipid composition constant. 🔬 #CryoEM nicely confirmed the intended increase in particle size as measured by NTA and DLS. Furthermore, cryo-EM images showed a wider size range as well as the presence of #multilamellar structures in the larger particle formulations. The particle surface was found to be less polar with increasing size, and after showing that total mRNA encapsulation did not correlate with LNP size measurements, the impact of LNP size on innate immunogenicity in mice and non-human primates was studied. 🧪 The researchers show that in mice LNPs smaller than 85–100 nm induced significantly lower immunogenicity with respect to the size interval of 100–200 nm, whereas in non-human primates all tested LNPs in the 60-150nm size range triggered a strong immune response when the LNPs were delivered intramuscularly, suggesting species-specific differences in LNP size sensitivity. 📑 Read the study: https://lnkd.in/gu4fgxTs 👉 Learn more about phase appropriate characterization of #lipidnanoparticles: https://lnkd.in/g5s7Pk7z

FYI: 5 Advantages of mRNA Vaccines 1. Safety: No risk of evolution/resurgence, mutation/recombination, or integration into host genome. 2. Cellular Immune Response: More comprehensive, stronger and durable immune response. 3. Short R&D cycle: DNA sequence to mRNA/LNP only takes 2 months. 4. Easy to Scale Production: The mRNA manufacturing process does not involve cells, and one liter of IVT reaction can generate 100,000 doses. 5. Multivalent Vaccine Possible: Different mRNA sequences can be encapsulated in a single LNP. Have any questions on how to develop mRNA vaccines? We are happy to help you.

The authors of this paper investigated and reported which cell types LNPs stimulate and show immunostimulatory activity. They prepared empty LNPs without mRNA using the ionizable lipid used in the marketed Corona vaccine, added them to several cell types in vitro, and evaluated the chemokines produced by these cells. The results showed that lymphatic endothelial cells (LECs) produced chemokines involved in the recruitment of monocytes/neutrophils. This suggests that LECs would act as the first signaling cells in response to LNP. https://lnkd.in/efSesxSW #LNP, #lipidnanoparticles, #stimulate, #immunostimulatory, #ionizablelipid, #mRNA, #LEC

Messenger RNA (mRNA) vaccines have great potential for the treatment of human diseases. However, problems such as the production of reactive oxygen species during mRNA translation can greatly affect translation efficiency, which in turn limits the application of mRNA vaccines. In view of this, researchers have developed a new strategy to significantly improve the efficacy of mRNA vaccines by promoting mRNA translation and stimulating the activation of interferon genes (STING). https://lnkd.in/gUDCCJt8
