    c-di-GMP heterogeneity is generated by the chemotaxis machinery to regulate flagellar motility

    Bridget R Kulasekara et al.
    Real time measurements of c-di-GMP in individual cells reveal an unexpected mechanism by which the chemotaxis machinery controls c-di-GMP heterogeneity, thereby regulating flagellar-based motility.

    β3-Adrenoceptor redistribution impairs NO/cGMP/PDE2 signalling in failing cardiomyocytes

    Sophie Schobesberger et al.
    β3-AR signalling via cGMP in cardiomyocytes is regulated via phosphodiesterase 2 and 5 degradation, it is potentially cardioprotective, but dysregulated in heart failure through signal redistribution and higher phosphodiesterase activity.

    Sir2 phosphorylation through cAMP-PKA and CK2 signaling inhibits the lifespan extension activity of Sir2 in yeast

    Woo Kyu Kang et al.
    The deacetylase Sir2 fine-tunes transcription of PMA1 and other aging related genes in a cAMP-PKA and CK2 signaling dependent manner.

    A synthetic peptide that prevents cAMP regulation in mammalian hyperpolarization-activated cyclic nucleotide-gated (HCN) channels

    Andrea Saponaro et al.
    Cell-penetrating peptide drugs prevent adrenergic regulation of pacemaker channels without altering the overall response of the cell to cAMP.

    Structure and mechanism of a Hypr GGDEF enzyme that activates cGAMP signaling to control extracellular metal respiration

    Zachary F Hallberg et al.
    A newfound signaling enzyme that diverged from a protein family ubiquitous in bacteria provides mechanistic insights into how new signaling activity emerges to control distinct cellular function and physiology.

    PDE2A2 regulates mitochondria morphology and apoptotic cell death via local modulation of cAMP/PKA signalling

    Stefania Monterisi et al.
    The enzyme phosphodiesterase 2A2 localises at the mitochondrial membrane and its inhibition results in a local increase in cAMP concentration, mitochondrial elongation and resistance to apoptosis.

    Mechanistic insight into the conserved allosteric regulation of periplasmic proteolysis by the signaling molecule cyclic-di-GMP

    Debashree Chatterjee et al.
    Structure-function analyses reveal the mechanistic underpinnings of inside-out transmembrane signaling that controls periplasmic proteolysis, and thereby biofilm formation, in bacteria and may be relevant in the context of other signaling proteins with similar control elements.

    cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool

    Vladimir Camarena et al.
    cAMP is identified to play a novel role in regulating DNA demethylation and gene transcription by augmenting the intracellular reactive Fe(II) pool.

    The mucosal adjuvant cyclic di-GMP enhances antigen uptake and selectively activates pinocytosis-efficient cells in vivo

    Steven M Blaauboer et al.
    In mice, cyclic di-GMP is an effective mucosal pneumococcal vaccine adjuvant that stimulates the immune response via two distinct mechanisms.

    Differences and similarities between human and chimpanzee neural progenitors during cerebral cortex development

    Felipe Mora-Bermúdez et al.
    Neural progenitors in humans and chimpanzee organoids show remarkably similar cellular and molecular parameters, but metaphase is longer during human mitosis.
