Introduction

This part of the project was focus on two points:

fusion between the vesicle and the targeted bacteria.

- to enable gene transcription after fusionning OMVs with the outer membrane of the receiving bacterium.

We also hope that we could achieve this aim without sacrifying important proprieties of our message : specific, repeatable , multidirectional. It seems that we have two possible ways : the ABC transporters or the two component systems . ABC transporters and two component systems are natural transport system (export or import) of information, nutriments or toxines.

There is another possibility but the mecanism is mostly unknown : the DNA-containing OMVs which could be a useful mean of information transport.
