Characterization and quantification of the interaction between the NFL-TBS.40‐63 peptide and lipid nanocapsules
Several studies previously showed that the NFL-TBS.40–63 peptide (NFL-peptide) is capable to specifically penetrating several glioblastoma cell lines (rat, mouse, human) and inhibiting their cell division in vitro and their tumor development in vivo. When lipid nanocapsules (LNCs) are functionalized...

| description | Several studies previously showed that the NFL-TBS.40–63 peptide (NFL-peptide) is capable to specifically penetrating several glioblastoma cell lines (rat, mouse, human) and inhibiting their cell division in vitro and their tumor development in vivo. When lipid nanocapsules (LNCs) are functionalized with the NFL-peptide, their absorption is targeted in glioblastoma cells both in vitro and in vivo. In the present study, we investigated the molecular architecture of these nanovectors (LNC-NFL) by using several microscopy techniques (transmission electron microscopy, cryo-electron microscopy, and cryo-electron tomography). We also used high-performance liquid chromatography (UPLC) technique to evaluate the interaction between LNCs and peptides. The work shows that the NFL-peptide forms stable long filaments along which the lipid nanocapsules interact strongly to form some sort of nanomolecular bracelets. This new construction composed of the NFL-peptide and lipid nanocapsules shows a better internalization in rat glioblastoma cells (F98 cells) than lipid nanocapsules alone. |
