Abstract:A new lipid system broadening the capacity of antigen carriage, including mRNA and protein, is established, and an assembled virus-like-structure (VLS) encapsulated mRNA of S1 protein from XBB.1 and loaded S1 protein from omicron BA.1 on the surface is identified. This characterized VLS enables to specifically augment mRNA expression in human respiratory epithelial cells and macrophages via its loaded S1 protein on the surface interacting with ACE2 or DC-SIGN molecules of cells. It also archives effective mRNA… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
