1. Regulation of bacterial adaptive behavior by the second messenger cyclic-di-GMP and host components
Abstract : To optimize survival and growth, bacteria have evolved adaptive behaviors that respond to relevant environmental signals. A switch from the motile to the sessile lifestyle is probably the most ancient behavioral transition of microorganisms. READ MORE

2. Characterization of c-di-GMP signaling in Salmonella typhimurium
Abstract : Signal transduction via cyclic nucleotides is a general mechanism utilized by cells from all kingdoms of life. Identification of cyclic diguanosine monophosphate (c-di-GMP) as an allosteric activator of the cellulose synthase in Gluconacetobacter xylinus 20 years ago, paved the way for the discovery of a novel general signalling system which is unique to bacteria.

3. Diverse cyclic dinucleotide signals regulate Escherichia coli lifestyle transition
Abstract : Bacteria have the ability to change their lifestyle to adapt to various environmental conditions. Cyclic dinucleotides (cDNs) are ubiquitous second messengers that can regulate fundamental lifestyle switches, such as motility versus sessility and acute versus chronic virulence, in bacteria.

4. Role of c-di-GMP signalling in bacterial-host interactions
Abstract : Bacteria have various ways to sense environmental signals and to adapt their behavior and physiology through different signaling systems. Secondary messenger signaling, amplified by enzymatic activity, rapidly transmits a signal in the cell, resulting in allosteric functional control. READ MORE

5. Nitric oxide (NO) and carbon monoxide (CO): A novel class of messenger molecules regulating insulin and glucagon secretion
Abstract : During the last decade it has been shown that nitric oxide (NO) and carbon monoxide (CO) are produced in our own body, and that they constitute a novel class of messenger molecules. In 1992 a constitutive NO-producing NO-synthase (cNOS) was found in the islets of Langerhans, and in 1997 we could show for the first time that the islets also contained a CO-producing constitutive heme oxygenase (HO-2).
