Lymphatic-targeted cationic liposomes: A robust vaccine adjuvant for promoting long-term immunological memory

Highlights • OVA antigen was encapsulated with mannosylated DOTAP liposomes (LP-Man) to generate lymphatic-targeted liposome vaccines. • LP-Man vaccines showed increased accumulation in secondary lymphoid organs and enhanced uptake by antigen-presenting cells. • LP-Man vaccines led to vigorous and p...

Zusammenfassung:Highlights • OVA antigen was encapsulated with mannosylated DOTAP liposomes (LP-Man) to generate lymphatic-targeted liposome vaccines. • LP-Man vaccines showed increased accumulation in secondary lymphoid organs and enhanced uptake by antigen-presenting cells. • LP-Man vaccines led to vigorous and persistent germinal center responses. • LP-Man vaccines increased Tfh cells and central memory CD4+ T cells in the secondary lymphoid organs. • LP-Man vaccines elicited sustained antibody production and robust recall responses three months after priming.
