abstract = {Direct delivery of proteins and peptides into living
mammalian cells has been accomplished using phospholipid
liposomes as carrier particles. Such liposomes are usually
taken up via endocytosis where the main part of their cargo
is degraded in lysosomes before reaching its destination.
Here, fusogenic liposomes, a newly developed molecular
carrier system, were used for protein delivery. When such
liposomes were loaded with water-soluble proteins and
brought into contact with mammalian cells, the liposomal
membrane efficiently fused with the cellular plasma membrane
delivering the liposomal content to the cytoplasm without
degradation. To explore the key factors of proteofection
processes, the complex formation of fusogenic liposomes and
proteins of interest and the size and zeta potential of the
formed fusogenic proteoliposoms were monitored.
Intracellular protein delivery was analyzed using
fluorescence microscopy and flow cytometry. Proteins such as
EGFP, Dendra2, and R-phycoerythrin or peptides such as
LifeAct-FITC and NTF2-AlexaFluor488 were successfully
incorporated into mammalian cells with high efficiency.
Moreover, correct functionality and faithful transport to
binding sites were also proven for the imported proteins.},
