August 15, 2021

A study conducted by Vigil et al. 2021 from Astrazeneca Biopharmaceuticals R&D showcases the applicability of high-content fluorescent imaging as a technique for the rapid characterization of mRNA-LNPs generated from a NanoAssemblr® mixing device in order to determine the optimal conditions for transfection that minimize cellular cytotoxicity and maximize mRNA internalization. Through high-content fluorescent imaging, mRNA-LNP characteristics such as transfection parameters, transfection-induced cytotoxicity, mRNA delivery, and mRNA translation were investigated in HEPG2 two dimensional monolayer and three dimensional spheroid cell cultures. This research demonstrates the value in utilizing high fluorescent imaging especially for future studies toward the development of novel gene therapies and drug candidates for various disease areas.

Naturally-occurring Cholesterol Analogues in Lipid Nanoparticles Induce Polymorphic Shape and Enhance Intracellular Delivery of mRNA

S. Patel, N. Ashwanikumar, E. Robinson, Y. Xia, C. Mihai, J.P. Griffith III, S. Hou, A.A. Esposito, T. Ketova, K. Welsher, J.L Joyal, Ö. Almarsson and G. Sahay

Endosomal sequestration of lipid-based nanoparticles (LNPs) remains a formidable barrier to delivery. Herein, structure-activity analysis of cholesterol analogues reveals that incorporation of C-24 alkyl phytosterols into LNPs (eLNPs) enhances gene transfection and the length of ...
