Harnessing the Therapeutic Potential of Cell Secretomes and Extracellular Vesicles for Craniofacial Regenerative Applications

open access: yesJournal of Periodontal Research, EarlyView.
The scoping review summarizes the current preclinical and clinical evidence for the use of “cell‐free” therapies in craniofacial (periodontal, bone and soft‐tissue) regeneration. It also aims to highlight key challenges and strategies towards the clinical translation of these therapies.

Nanoparticles in Periodontology and Implant Dentistry: From Mechanisms to Clinical Applications

open access: yesJournal of Periodontal Research, EarlyView.
Nanotechnology holds significant promise in improving dental care, yet there is a need for more reliable clinical studies to validate its effectiveness and safety. ABSTRACT Recent advances in nanotechnology are reshaping the landscape of periodontology and implant dentistry, particularly through the application of nanoparticles (NPs).

Naturally Occurring CodY Variants Alter Ligand Binding, DNA Target Affinity, and Virulence in Clostridioides difficile

open access: yesMolecular Microbiology, EarlyView.
Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

To Move or Not to Move: When and How Bacteria Suppress Flagellar Motility

open access: yesMolecular Microbiology, EarlyView.
Motility cessation in bacteria is a key regulatory strategy that provides multiple survival advantages including enhanced community cooperation, niche adaptation and evasion of host immune responses. This process is controlled by associated mechanisms such as post‐translational modifications and second messenger signalling that stabilise non‐motile ...

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

open access: yesOral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Mechanisms of Cyclic-di-GMP Signaling in Bacteria

Annual Review of Genetics, 2006
Cyclic-di-GMP is a ubiquitous second messenger in bacteria. The recent discovery that c-di-GMP antagonistically controls motility and virulence of single, planktonic cells on one hand and cell adhesion and persistence of multicellular communities on the other has spurred interest in this regulatory compound.

Measuring Individual Cell Cyclic di-GMP: Identifying Population Diversity and Cyclic di-GMP Heterogeneity

open access: yes, 2020
Cyclic di-GMP is a second messenger used by bacteria to regulate motility, extracellular polysaccharide production, and the cell cycle. Recent advances in the measurement of real time cyclic di-GMP levels in single cells have uncovered significant dynamic heterogeneity of second messenger concentrations within bacterial populations.

Regulation by Cyclic di-GMP in Myxococcus xanthus

open access: yes, 2020
Myxococcus xanthus has a complex lifecycle that is regulated by nutrient availability. In the presence of nutrients, M. xanthus cells grow, divide, and move to assemble into colonies that feed cooperatively either saprophytically or on prey. In response to starvation, a developmental program is initiated that culminates in formation of multicellular ...

Cyclic di-GMP as a second messenger

Current Opinion in Microbiology, 2006
In many bacteria bis-(3',5')-cyclic dimeric guanosine monophosphate (c-di-GMP) signaling determines the timing and amplitude of complex biological processes from biofilm formation and virulence to photosynthesis. Thereby, the tightly regulated temporal and spatial activity patterns of GGDEF and EAL domain proteins, which synthesize and degrade c-di-GMP,
