Project description
Mapping adaptive signalling in pathogenic bacteria
Bacteria have an inherent capacity to quickly respond to external cues and adapt to changes in their immediate environment. Adaptation of cell behaviour involves the transmission of signals inside the cell through specific pathways. Scientists of the EU-funded SNiB-cdG-P project are interested in cyclic di-guanosine-monophosphate (c-di-GMP), a key signalling molecule implicated in bacterial growth and survival. Using state-of-the-art proteomics and mass spectrometry techniques, they will focus on mapping the c-di-GMP signalling network in Gram-negative bacteria. Results will help understand the implication of c-di-GMP in antibiotic resistance and bacteria pathogenesis.
Objective
To survive in diverse niches, bacteria must adapt to changes in their local environment by sensing and responding to environmental cues. External cues are transduced through complex signaling networks throughout a cell and drive diverse changes in cellular behavior. In bacteria, cyclic di-guanosine-monophosphate (c-di-GMP) is a nucleotide-derived second messenger that mediates signal transduction of important biological processes for bacterial growth and survival e.g. motility, biofilm formation and metabolism. These biological processes are also crucial in clinical settings as they underlay antibiotic resistance in important pathogenic bacteria. Recent advances in MS-based proteomics have provided different tools to investigate the proteome of an organism in a systematic and global manner. Especially, thermal proteome profiling (TPP) and limited-proteolysis MS (LiP-MS) are pioneering methods to study change of protein states proteome-wide. I aim to employ these proteomics based approaches to achieve the global map of the c-di-GMP signaling network in two different bacteria, Escherichia coli and Caulobacter crescentus, both are model organisms of Gram-negative bacteria. Furthermore, I will apply these methods to investigate signaling network of another important second messenger, (p)ppGpp, and explore how the networks of these two messenger molecules interact in bacteria to dictate cellular physiology.

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
