Modular analysis of the control of flagellar Ca2+-spike trains produced by CatSper and CaV channels in sea urchin sperm [PDF]

open access: yes, 2020
Intracellular calcium ([Ca2+]i) is a basic and ubiquitous cellular signal controlling a wide variety of biological processes. A remarkable example is the steering of sea urchin spermatozoa towards the conspecific egg by a spatially and temporally ...

Phosphodiesterase 3 inhibitors boost bone outgrowth

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose C‐type natriuretic peptide (CNP) stimulates skeletal growth by acting on the growth plates of long bones, and a CNP variant is clinically used for achondroplasia treatment. We previously reported that CNP stimulates the autonomic Ca2+ influx mediated by TRPM7 channels in growth plate chondrocytes to facilitate extracellular ...

Cloning and functional complementation of ten Schistosoma mansoni phosphodiesterases expressed in the mammalian host stages.

open access: yesPLoS Neglected Tropical Diseases, 2020
Only a single drug against schistosomiasis is currently available and new drug development is urgently required but very few drug targets have been validated and characterised.

The ever unfolding story of cAMP signaling in trypanosomatids: vive la difference! [PDF]

open access: yes, 2015
Kinetoplastids are unicellular, eukaryotic, flagellated protozoans containing the eponymous kinetoplast. Within this order, the family of trypanosomatids are responsible for some of the most serious human diseases, including Chagas disease (Trypanosoma ...

Compartmentalisation in cAMP signalling: A phase separation perspective

open access: yesBritish 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.

Synergistic effect of phosphodiesterase 4 inhibitor and serum on migration of endotoxin-stimulated macrophages. [PDF]

open access: yes, 2018
Macrophage migration is an essential step in host defense against infection and wound healing. Elevation of cAMP by inhibiting phosphodiesterase 4 (PDE4), enzymes that specifically degrade cAMP, is known to suppress various inflammatory responses in ...

STING-dependent recognition of cyclic di-AMP mediates type I interferon responses during Chlamydia trachomatis infection. [PDF]

open access: yes, 2013
UnlabelledSTING (stimulator of interferon [IFN] genes) initiates type I IFN responses in mammalian cells through the detection of microbial nucleic acids. The membrane-bound obligate intracellular bacterium Chlamydia trachomatis induces a STING-dependent

Non‐canonical PKG1 regulation in cardiovascular health and disease

open access: yesBritish 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 effects of portacaval shunt upon hepatic cholesterol synthesis and cyclic AMP in dogs and baboons [PDF]

open access: yes, 1980
Hepatic cholesterol synthesis, hepatic cyclic AMP, and portal and peripheral insulin and glucagon levels were investigated in nine dogs and three baboons after complete portacaval shunt.

Clinically relevant enhancement of human sperm motility using compounds with reported phosphodiesterase inhibitor activity [PDF]

open access: yes, 2014
STUDY QUESTION: Can we identify compound(s) with reported phosphodiesterase inhibitor (PDEI) activity that could be added to human spermatozoa in vitro to enhance their motility without compromising other sperm functions?
