Exosome booster

• Considering that TIL cells can't secret enough exosomes under normal condition, we fuse three genes to increase the number of exosomes (Alenquer, 2015), thus increasing the transfer efficiency of exosomes.
• Exosome booster refers to hSDC4-T2A-STEAP3-P2A-NadB.We identified STEAP3 (involved in exosomebiogenesis), syndecan-4(SDC4; supports budding of endosomal membranes to form multivesicular bodies), and a fragment of L-aspartate oxidase (NadB; possibly boosts cellular metabolism by tuning up the citric acid cycle) as potential synthetic exosome production boosters. Combined expression of these genes significantly increased exosome production.(Ryosuke Kojima et al. 2008)

They combine with each other to boost exosomal transfer efficiency：

• In previous article, it use IRES (internal ribosome entry site,IRES) to connect three genes, we change it into linkers T2A and P2A to ensure proper expression of three genes.Then we use use reporter gene copGFP to manifest the expression of exosome booster with the promoter of 5-HRE-PminCMV.

• Here is the final device that we designed for this project.

It combines with exosome booster and miR attacker under control of induced promoter.More details and description you can obtain in our wiki!
