34 students initially applied for the team. Project proposals were due March 10 and we received 13 different project ideas. Both supervisors will evaluate the proposed projects and select the team members (possibly) by April 10.

Mammalian systems can be a subject of cellular engineering similarly to bacterial cells. We decided to tinker with the existing cell signaling network of the response to the bacterial infection. Binding of bacterial components (PAMPs – Pathogen associated molecular patterns) to a family of Toll-like receptors activates the cells of the immune system but the exaggerated response may lead to systemic inflammation and sepsis which is often fatal. We designed a feedback loop, which inhibits the signaling cascade at the »weak spot« - MyD88, a consensus adaptor protein of the Toll-like receptors. A mathematical model of cell activation with engineered feedback loop was constructed, which predicts the decrease of the cellular activation after the repeated stimulation. Twenty-six new BrioBricks were constructed specially for the mammalian system. We have experimentally confirmed the function of the feedback device by detecting the inhibition of cellular activation after the repeated stimulation. Cell activation decreased without completely deleting the responsiveness to the bacterial infection, thus our engineered cell system represents a type of artificial immunotolerance.
