Motivation
We hope to develop a fresh-expression transdermal vaccination.
We hope everyone in this world could equally enjoy the benefit of medical progress.

Design of Project
With the support of TD-1, a special polypeptide which can greatly facilitate macromolecule transdermal delivery through intact skin, we construct three different fuctional engineered bacillus subtilis; besides, we design a reporter system, including a kill switch, in the fouth type B.subtilis to improve usability and ensure biosafety.
ANTIGEN
As the core of our in-situ system,
TD1-antigen expresser is designed
and will share a great percentage of
the total bacteria in our "band-aid".

LTB
As one kind of our adjuvant expresser,
TD1-LTB is used to enhance the antigenicity.
For LTB has so many advantages, it's a wild using adjuvant for most of exsiting injected vaccine.

TNFα
It's worth mentioning that to improve the effects of
traditional vaccine, as another kind of our TD1-adjuvant expresser, TNFα bear the weight of our hope to increase the sensitivity of our immune system.

REPORTER
Reporter notifies users whether the status of vaccine patch is all right and when they can stick the patches to arms . Further more killing switch is conveyed in them as a biosafety guard.

Experimental Measurement
Molecules part
We took E.coli and the PET vector as the positive control and realized our ideas in the B.subtilis expression system based on PHT43 shuttle vector.

Protein part
Before we achieve fresh expression, we use purified protein to obtain accurate data to verify our assumptions.

Mice experiments
The most obvious character of our 2013USTC iGEM team is that we have not only achieved a series of molecule experiments but also tried mice experiments, which could be divided into transdermal experiments in vitro and animate mice experiments
