Web15 de mai. de 2024 · The current COVID-19 mRNA-LNPs vaccines must be stored at (ultra)low temperatures. The core of LNPs contains mRNA, an ionizable cationic lipid, a neutral lipid and water. mRNA hydrolysis is the determining factor for mRNA-LNP instability. Improving stability through mRNA molecule optimization should be prioritized. WebLiposomes and polycations are two major nonviral gene delivery carriers. Liposome-based carriers such as Lipofectamine have been widely used as nonviral vectors to deliver numerous genes; however, safety and efficiency have yet to be achieved, due to their cytotoxicity, low transfection efficiency, and nonspecific uptake.
