I'm saving the html scripts I've changed in case anyone needs them back!
 
-
Templates 08 and 08a Done.
 
-
Protocols page done.
 
-
Please note UK spelling! So double L for signalling and Modelling pages please! Please ammend your own links if you've got it wrong.
 
-
Noticed that the two titles by the end of the B.subtilis transformation protocol page have no content. What's that? Perhaps an answer from Ian? Dan? Marie?

This year, the Cambridge iGEM team is working towards creating an integrated Bacterial Recombinant Artificial Intelligence Network (iBRAIN). Our concept is to model eukaryotic neural behaviour using populations of bacteria. We are looking at two main aspects of this concept: self-organisation using Turing pattern formation, and synaptic signal transduction using voltage output glutamate detection

In order to simulate neural activity in bacteria, a mechanism resembling a synapse is necessary. At the synapse, neurotransmitter molecules are released from the presynaptic plasma membrane. The neurotransmitter diffuses through the synaptic cleft and binds to chemical receptor molecules on the membrane of the postsynaptic cell. These receptors cause ion channels to open so that ions rush out, changing the transmembrane potential.

Signalling Bacillus Voltage Modelling

Overview

Since the emergence of Synthetic Biology, bacteria have been engineered to perform a wide variety of simple tasks. They can be made to express proteins, respond to their environment and communicate primitively with each other. Presently, a key goal for the field is to create a communicating, organised and differentiated population of bacteria that can be considered a multicellular organism, capable of performing even more complex tasks. The ultimate goal for this line of research would be to mimic a brain, the most complex structure in the universe. To realize this goal requires the development of systems for rapid, robust communication and self-organised differentiation.
Our project sets the foundation for future research in engineered multi-cellularity by pursuing electrical and peptide signalling, and cellular self-differentiation through spontaneous spatial patterning.

Voltage

In order to simulate neural activity in bacteria, a mechanism resembling a synapse is necessary. At the synapse, neurotransmitter molecules are released from the presynaptic plasma membrane. The neurotransmitter diffuses through the synaptic cleft and binds to chemical receptor molecules on the membrane of the postsynaptic cell. These receptors cause ion channels to open so that ions rush out, changing the transmembrane potential. Attempting to mimic this in a prokaryotic system is particularly attractive as, in a more general sense, it provides an interface between chemical or biological and electrical systems.
Using the amino acid glutamate as our 'neurotransmitter', we have successfully demonstrated a voltage response in bacterial cells. Read on...

Signalling

Using peptide-based signalling systems from gram-positive bacteria, we have laid the foundations for a self-organising biological system, capable of expressing spatial patterns of GFP expression on a bacterial lawn. The focus of our investigation was on a simple two-component Reaction-Diffusion system, allowing for simple spatial 'patterning' of gene expression. The simplest of these patterns mimic the spots and stripes seen on animal coats.

To build more complex cellular systems, new tools and techniques are required. We are generating standardized parts, tools, and techniques for the gram-positive chassis ''B. subtillis''. Easy to handle and transform, this bacterium offers many adantages to ''E. coli', including the ability to secrete proteins and integrate DNA into the chromosome. We have designed, built, and submitted gram-positive RBSes, promoters, and shuttle vectors.
As a part of this work we have confirmed single copy chromosomal insertion, demonstrated InFusion assembly, and characterized an improved GFP variant. Read on...

We have introduced a model of the AGR quorum-sensing system of S.aureus to illustrate how a typical quorum-sensing system works. The model predicts theoretical values for biological parameters (such as the threshold cell density) that can be verified and we will be also be able to predict how the system behaves if we change a number crucial parameters. This can be extremely useful in informing design decisions when building a synthetic device. We have also expanded this model into a hypothetical setup with a second parallel agr-system.
