Synthesis of the Targeted Biobrick
The synthesized genome will be capable of producing gene therapy "viroins" with protein C specially modified. This targeted biobrick enables the synthetic gene therapy vector to be targeted specifically for certain types of cells. We generally decouple this biobrick into four "modules" (will be expressed to different domains in the C-Fiber fusion protein).
Functioning of the targeted gene therapy vector
An idealized model for the functioning of the targeted gene therapy vector is proposed. After the injection of the purified gene therapy vectors, the vectors will conveyed to target cells by circulation (specific situations should be discussed with respect to different types of cells and different diseases). The synthetic vectors will invade into the target cells in a manner similiar to the wildtype adenovirus-attachment and internalization. This function is empowered by the targeted biobrick in the synthetic genome.
Firstly, the tissue-specific peptide (selected by phage display) on the surface of the viroin will attach to the receptors on the surface of the target cells. Secondly, the RGD domian at the bottom of the engineered fiber will interact with integrin of the targeted cells, thus internalize the whole viroin by endocytosis.
