Georgia Tech researchers have designed and produced a protein nanocarrier, a drug delivery device, made from proteins capable of carrying any antibody. Antibodies are attached to the assembled protein core to create the nanoscale drug delivery carrier. The protein core is completely degradable and is small relative to the size of the antibodies it carries. It also enables a multitude of antibodies, of the same or different types, to reach and penetrate active cells. This design allows antibodies to effectively reach intracellular target of a variety of diseases in an unprecedented way.
- Self-assembling – Forms an organized structure in water at room temperature
- Nano-scale – Approximately 35 nm, ideal for intracellular uptake
- Versatile – Can be used with any antibody
- Novel approach – Opens up an entire new class of protein drugs that can deliver therapeutics inside cells
- Diseases via intracellular protein targeting
There is a significant list of “undruggable” diseases, meaning diseases that are related to intracellular protein interactions that small molecules cannot block. While many antibodies with intracellular targets exist, they can only be used as research tools because the antibodies cannot penetrate live cells. Delivering sufficient amounts of functional antibody inside live cells is a challenge that research has not been able to overcome.
