Activation of Gingival Fibroblasts by Bacterial Cyclic Dinucleotides and Lipopolysaccharide
Pathogens, 2020 Human gingival fibroblasts (HGFs) recognize microbe-associated molecular patterns (MAMPs) and respond with inflammatory proteins. Simultaneous impacts of bacterial cyclic di-guanosine monophosphate (c-di-GMP), cyclic di-adenosine monophosphate (c-di-AMP),

Convergence of Lasserre's hierarchy: the general case [PDF]
Optimization Letters 16(3):1015-1033, 2022, 2020 Lasserre's moment-SOS hierarchy consists of approximating instances of the generalized moment problem (GMP) with moment relaxations and sums-of-squares (SOS) strenghtenings that boil down to convex semidefinite programming (SDP) problems. Due to the generality of the initial GMP, applications of this technology are countless, and one can cite among ...

Nucleotides as Bacterial Second Messengers
Molecules, 2023 In addition to comprising monomers of nucleic acids, nucleotides have signaling functions and act as second messengers in both prokaryotic and eukaryotic cells. The most common example is cyclic AMP (cAMP).

Dual Regulatory Role Exerted by Cyclic Dimeric GMP To Control FsnR-Mediated Bacterial Swimming
mBio, 2022 Bacterial motility has great medical and ecological significance because of its essential role in bacterial survival and pathogenesis. Cyclic dimeric GMP (c-di-GMP), a second messenger in bacteria, is the predominant regulator of flagellar synthesis and ...

Estimating the rate constant of cyclic GMP hydrolysis by activated phosphodiesterase in photoreceptors [PDF]
THE JOURNAL OF CHEMICAL PHYSICS 129, 145102 (2008), 2008 The early steps of light response occur in the outer segment of rod and cone photoreceptor. They involve the hydrolysis of cGMP, a soluble cyclic nucleotide, that gates ionic channels located in the outer segment membrane. We shall study here the rate by which cGMP is hydrolyzed by activated phosphodiesterase (PDE).

The HD-GYP Domain, Cyclic Di-GMP Signaling, and Bacterial Virulence to Plants
Molecular Plant-Microbe Interactions, 2006 Cyclic di-GMP is an almost ubiquitous second messenger in bacteria that was first described as an allosteric activator of cellulose synthase but is now known to regulate a range of functions, including virulence in human and animal pathogens. Two protein
