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

Differential segment‐specific signalling pathways for guanylate cyclase C‐activated anion secretion in murine ileocolon

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Guanylate cyclase‐C (GC‐C) is the receptor for endogenous (uro)guanylin peptides, bacterial toxins and pharmacological analogues. Receptor activation leads to intestinal fluid loss, but also activates an antiproliferative pathway and is a promising target in colorectal cancer therapy.

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, EarlyView.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Sodium thiosulfate treatment rescues hyperglycaemia‐induced pronephros damage in zebrafish by upregulating nitric oxide signalling

The Journal of Physiology, EarlyView.
Abstract figure legend Sodium thiosulfate (STS) rescues the pronephros phenotype of pdx1 morphants through compensatory upregulation of nitric oxide (NO) metabolism. Zebrafish larvae injected with a control morpholino show the typical pronephros structure at 48 h post‐fertilization (hpf) with and without STS treatment.

Assessment of exercise tolerance using cardiopulmonary exercise test in patients with chronic obstructive pulmonary disease and secondary pulmonary arterial hypertension treated with Sildenafil versus those receiving only standard-of-care

The Egyptian Journal of Bronchology
Background Pulmonary arterial hypertension (PAH) is a common complication of chronic obstructive pulmonary disease (COPD), which can lead to shorter survival and poor clinical outcomes.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Anti‐Biofilm Properties of Polyurethane Biomaterials Tethered With Small Molecules via Polyethylene Glycol Linker

Journal of Biomedical Materials Research Part A, Volume 114, Issue 4, April 2026.
Interfering with nucleotide signaling pathways using small molecules represents a promising strategy to disrupt biofilm formation on biomaterial surfaces. This study reported a new approach for tethering small molecules onto polyurethane surfaces using a PEG long linker.

Future Prospects of Imatinib in Advanced Pulmonary Hypertension Management

IUBMB Life, Volume 78, Issue 3, March 2026.
ABSTRACT Pulmonary arterial hypertension (PAH) is a severe, progressive disease characterized by elevated pulmonary arterial pressure and increased vascular resistance. This hemodynamic strain forces the right ventricle to pump against a high‐pressure system, ultimately leading to right‐sided heart failure and death.

Distinct Thromboxane A₂–Dependent Pathways Regulate Arachidonic Acid–Triggered VASP Phosphorylation at Ser239 and Ser157 in Human Platelets: Real‐Time Visualization Reveals Superior Antithrombotic Efficacy by Targeting Thromboxane A₂ Signaling over Cyclooxygenase Inhibition

Journal of Cellular Physiology, Volume 241, Issue 3, March 2026.
ABSTRACT Platelets, as anucleate blood cells, play a pivotal role in the pathogenesis of cardiovascular diseases (CVDs), making antiplatelet therapy essential for preventing thrombotic events such as myocardial infarction. Thromboxane A₂ (TXA₂) is a key pro‐aggregatory mediator that drives platelet activation.
