SEND delivery device

Part Description

Our delivery system SEND platform which formed of 3 domains the first component PEG10 which is GAG protein forms capsid or vesicle incircles its own mRNA and self-assembles into virion-like. The second component : VSVg-Fusogen is a typical type III viral fusion protein that, will mediate the delivery of VLPs to target tissues (hepatocytes). Third component: cargo RNA the RNA needed to be carried by the VLPs which is the mRNA of PAH with the addition of 5’ UTR of PEG10 gene to ensure its casidation by PEG10 capsid.

Usage

We used a brand new platform to deliver our circuit to the targeted tissue by employing the capacity of PEG10 mRNA to be encapsidated by its expressed GAG protein to deliver the mRNA of PAH to hepatocytes through VLPs.

This was done by adding 5’ and 3’ UTR of PEG10 gene to PAH sequence to guarantee it’s encapsidation with PEG10 proteins And we employed VSVg-Fusogen to deliver PAH mRNA to the tissue of interest (hepatocytes) as shown in figure 1.
