Gene delivery to brain cells with apoprotein E derived peptide conjugated to polylysine (apoEdp-PLL)

Abstract: A promising strategy to carry genetic material to brain cells either in vitro or in vivo is using the LDL receptor (LDLr) on blood-brain barrier. LDLr naturally help to low density lipoproteins (LDL(S)) transporting across the BBB by endocytosis. Here we present the idea of using the LDLr-mediated pathway for transporting genetic material to brain cells. A tandem dimer Sequence of apoprotein-E (apoE) (141-150) conjugated to polylysine sequence was used as a novel DNA Delivery vector for transfecting of brain c… Show more

“…Specifically, LRP1 is a multifunctional receptor that interacts with a range of ligands, such as apolipoprotein E (ApoE), α 2 -macroglobulin, aprotinin, amyloid precursor protein, and Aß [213]. One of the first examples of targeted gene delivery to the brain by means of P(Lys) nanocarriers was reported by Mousazadeh and co-workers using this receptor to shuttle them across the BBB [214]. An LDL receptor-binding peptide dimer (LRKLRKRLLR-LRKLRKRLLR) derived from its endogenous ligand ApoE was conjugated to P(Lys) 16 .…”
