Ionizable lipidic systems are developed to reduce the toxicity while retaining the advantageous transfection characteristics. The mRNA is incorporated into the hydrophilic interior of the ionizable lipid. Specifically, the effective ionizable lipid's positive charge facilitates its electrostatic interaction, which aids in mRNA complexation and subsequent fusion with the negatively charged endosomal membrane for reduced toxicity post-injection. Furthermore, an ability for nanoparticles to ionize seems to be crucial to the endosomal escape process. Ideally, these novel ionizable lipids will allow for the safe and effective use of mRNA-based therapies in acute and chronic diseases.
