Introduction

This part of the project was focus on two points:

• The fusion between the OMVs and the targeted bacteria.

• The activation of the transcription of a genetic construction after fusionning the OMVs with the outer membrane of the receiving bacterium.

The sinequanone conditions : we tried to 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 systems (export or import) of nutriments or toxines, and even information, the mecanism is mostly unknown but the DNA-containing OMVs could be a useful mean of information transport. Here for information about ABC transporter and Two Component System.

C. Our strategy and D. Construction part explains our aim in this OMV production system.
