Caffeine affects the biological responses of human hematopoietic cells of myeloid lineage via downregulation of the mTOR pathway and xanthine oxidase activity [PDF]

, 2015
Correction of human myeloid cell function is crucial for the prevention of inflammatory and allergic reactions as well as leukaemia progression. Caffeine, a naturally occurring food component, is known to display anti-inflammatory effects which have ...

DNA sensor cGAS-mediated immune recognition

Protein & Cell, 2016
The host takes use of pattern recognition receptors (PRRs) to defend against pathogen invasion or cellular damage. Among microorganism-associated molecular patterns detected by host PRRs, nucleic acids derived from bacteria or viruses are tightly ...

Differential Sperm DNA Methylation Profiles in Healthy Men With High Versus Low Adherence to the Mediterranean Diet in the Led‐Fertyl Study

Andrology, EarlyView.
ABSTRACT Background Diet is known to play an essential role not only in sperm quality but also in offspring health, likely mediated through the sperm epigenome. Moreover, one of the main components of the Mediterranean diet (MedDiet) (i.e., nuts) have shown to impact sperm DNA methylation patterns.

“Cyclic nucleotides in plants: from obscure messengers to central regulators“

Frontiers in Plant Science
This review examines the historical trajectory of cyclic nucleotides (cNMPs) research in plants, a field that has encountered prolonged challenges and skepticism, contrasting sharply with its rapid validation in animal systems.

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.

The Molecular Organization of Human cGMP Specific Phosphodiesterase 6 (PDE6): Structural Implications of Somatic Mutations in Cancer and Retinitis Pigmentosa

Computational and Structural Biotechnology Journal, 2019
In the cyclic guanosine monophosphate (cGMP) signaling pathway, phosphodiesterase 6 (PDE6) maintains a critical balance of the intracellular concentration of cGMP by catalyzing it to 5′ guanosine monophosphate (5′-GMP).

New biosensors and transgenic mice for multiplex cGMP imaging

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a versatile second messenger that is important for human (patho‐)physiology and pharmacotherapy. Live‐cell imaging of cGMP with biosensors allows to elucidate its spatiotemporal dynamics in real time under close‐to‐native conditions. However, to monitor two separate cGMP pools or cGMP/cAMP

Characterisation of the anti-inflammatory and anti-proliferative effects of natriuretic peptides in rodents. [PDF]

, 2007
Natriuretic peptides are a family of vasoactive hormones that play important roles in cardiovascular homeostasis. These peptides exert biological effects primarily via activation of guanylate cyclase (GC)-coupled natriuretic peptide receptors (NPR) that ...

An intracellular recombinant single‐chain variable antibody fragment as a new class of phosphodiesterase type 5 inhibitors

British Journal of Pharmacology, EarlyView.
Background and Purpose Cyclic guanosine monophosphate (cGMP) is a ubiquitous second messenger involved in human (patho‐)physiology. Phosphodiesterase 5 (PDE5) is a major cGMP hydrolyzing enzyme in many cell types including vascular smooth muscle cells (VSMCs). Several highly selective PDE5 inhibitors are in clinical use. However, there are currently no
