Problems
Our Message in a Bubble project is fully integrated inside a reflection on communication between bacterias. Therefore, the modeling studies aimed at answering 3 major problematics directly linked to the improvement of messengers and messages efficiency :
- How can we get a synchronisation between the maximum concentration of proteins encapsulated and the maximum quantity of vesicules sent by time units thus improving the quality of signal sent ?
- Can we make vesicules only by overexpressing soluble parts of membrane proteins ?
- How can we optimize the quality of the reception i.e getting a robust response with a limited number of messengers sent ?
Results
The synchronisation between protein creation and vesicules creation was acheived by the use of a transcriptional cascade inside the genetic network thus leading the a delay between the maximum concentration of proteins and of the maximum creation of vesicules :
