<h1>Motivation</h1>
-
  Abstract: In our world, billions of people suffer from contagion, however, only part of them can be prevented by proper vaccine. Many disadvantages limit the usage of traditional vaccine especially in developing countries. This year, our project focused on a revolutionary vaccine delivery. We chose bacillus subtilis as chassis to establish a transdermal vaccine fresh secreting band-aid which consists of four engineering  b.subtilis, each of them carries a gene circuit independently. By using an excellent transdermal peptide TD1, three of them could express a serious of fusion proteins(antigen, 2 kinds of adjuvants) which could penetrating the skin and work as traditional vaccine molecule. The fourth type of them is our “reporter” which could notify users whether the band-aid works well and when they could stick or tear off the patch. Moreover we designed a reliable suicide system in bacillus subtilis for the very first time in iGEM. So it would be ok if our users tear patches off and throw them away. Cheap and convenient, we just create a world without needle.

TNFα is a chemotactic factor recruiting Langerhans Cells, the antigen presenting cells beneath the skin barrier. The TNFα expresser is responsible for collecting LC and triggering more intense immune responses.

In Situ Transdermal Vaccine

2013, We Redefined Vaccine
A Revolutionary Transdermal Vaccine
Safe, Reliable, Needle-free and Available for Everyone

Project

Motivation

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

Design of Project

With the support of TD-1, a special polypeptide which can greatly facilitate macromolecule transdermal delivery across intact skin, we constructed three different fuctional engineered Bacillus subtilis; besides, we designed 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 make up great percentage of
in the total bacteria in our "band-aid".
more
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 widely used adjuvant for most of exsiting injected vaccine.
more
TNFα
TNFα is a chemotactic factor recruiting Langerhans Cells, the antigen presenting cells beneath the skin barrier. The TNFα expresser is responsible for collecting LC and triggering more intense immune responses.
more
REPORTER
Reporter notifies users the status of vaccine patch and when to stick. Furthermore, it contains killing switch as a biosafety guard.
more

Experimental Measurement

Construction of Vectors
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.
more
Tests on fusion protein
To achieve fresh expression ultimately, we used purified protein to obtain accurate data and verify our design.
more
Immunogenicity experiments
The most prominent character of 2013USTC iGEM team is that we have not only achieved a series of molecule experiments but also conducted mice experiments, including in vitro transdermal experiments and mice experiments
