Why Is Pieter Cullis Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Pieter Rutter Cullis is a Canadian physicist and biochemist known for his contributions to the field of lipid nanoparticles . Lipid nanoparticles are essential to current mRNA vaccines as a delivery system. Prof. Cullis is best known for the development of ionizable cationic lipids. These lipids are able to complex with negatively charged nucleic acids at low pH where they are positively charged because they have a pKa if approximately 6.4. They reduce or eliminate toxicity associated with cationic lipids at physiological pH of 7.4 because they adopt a net neutral charge. Finally, they enable endosomal escape because they again become positively charged in acidified endosomes and promote formation of non-bilayer structures by interaction with negatively charged lipids. These properties are critical to the function of the mRNA vaccines and are rapidly enabling gene therapy in clinical settings.
