In previous work, researchers from CEINGE (Naples, Italy) and collaborating institutions developed an alternative gene therapy strategy based on the expression of a secreted fusion protein, including the extracellular portion of the human LDLR for LDL binding, linked to rabbit transferrin (TF), targeting the transferrin receptor (TFr), resulting in internalization and uptake of LDL particles. They have now published more recent work to further improve the efficacy and safety of this strategy.
