To assess the feasibility of utilizing the malaria circumsporozoite protein as a liver-specific ligand for targeted gene delivery into hepatocytes and other cell lines.
Chemically conjugated recombinant circumsporozoite (CS) proteins to poly(L-lysine) and complexed the conjugates with reporter plasmid DNA.
Transfected primary hepatocyte cultures with CS-DNA complexes in the presence and absence of adenovirus to overcome endosomal entrapment.
Evaluated transfection efficacy across multiple established cell lines (HepG2, HeLa, NIH3T3, K562, and HL-60) and determined the necessity of the conserved region II+ binding sequence.
CS-plasmid complexes induced low baseline reporter gene expression in primary hepatocytes, which increased markedly upon cotransfection with adenovirus.
Gene transfer depended strictly on the conserved region II+ amino acid sequence and occurred efficiently in HepG2, HeLa, NIH3T3, and K562 cells, but not in receptor-deficient HL-60 cells.
