Lipid nanoparticles used to deliver RNA in vaccines

September 30, 2019 / Victoria Rees

Researchers have developed a series of lipid nanoparticles, which encapsulate RNA, for effective and improved vaccine delivery. Researchers have developed a series of lipid nanoparticles to deliver RNA vaccines accurately, to ensure the therapy reaches the correct immune cells and produces sufficient amounts of the encoded protein. A team from the Massachusetts Institute of Technology (MIT), US conducted the research into the vaccine. They say it also behaves like an “adjuvant”, boosting the effectiveness of the treatment. Using mouse models, the researchers showed that the RNA vaccine is successful in inhibiting the growth of melanoma tumours. “One of the key discoveries of this paper is that you can build RNA delivery lipids that can also activate the immune system in important ways,” says Daniel Anderson, an associate professor at MIT and the senior author of the study. Anderson’s lab has previously developed lipid nanoparticles for delivering RNA and D...
