Obiettivo del progetto (Objective)
'Bacterial biofilms are the primary cause of chronic infections and of resulting infection relapses. To be able to interfere with bacterial persistence it is vital to understand the molecular details of biofilm formation and to define how motile planktonic cells transit into surface-grown communities. The nucleotide second messenger cyclic di-guanosinemonophosphate (cdGMP) has emerged as a central regulatory factor governing bacterial surface adaptation and biofilm formation. Although cdGMP signaling may well represent the Achilles heel of bacterial communities, cdGMP networks in bacterial pathogens are exquisitely complex and an integrated cellular system to uncover the details of cdGMP dynamics is missing. To quantitatively describe cdGMP signaling we propose to exploit Caulobacter crescentus, an organism with a simple bimodal life-style that integrates the sessile-motile switch into its asymmetric division cycle. We aim to: 1) identify the role and regulation of all diguanylate cyclases and phosphodiesterases that contribute to the asymmetric cellular program with the goal to model the temporal and spatial distribution of cdGMP during development; 2) identify and characterize cdGMP effectors, their downstream targets and cellular pathways; 3) elucidate how cdGMP coordinates cell differentiation with cell growth and propagation; 4) unravel the role of cdGMP as an allosteric regulator in mechanosensation and in rapid adaptation of bacteria to growth on surfaces; 5) develop novel tools to quantitatively describe cdGMP network dynamics as the basis for mathematical modeling that provides the predictive power to experimentally test and refine important network parameters. We propose a multidisciplinary research program at the forefront of bacterial signal transduction that will provide the molecular and conceptual framework for a rapidly growing research field of second messenger signaling in pathogenic bacteria.'
