Somatostatin modulation of initial fusion pores in Ca2+‐triggered exocytosis from mouse chromaffin cells

The Journal of Physiology, EarlyView.
Abstract figure legend Somatostatin binds to a G‐protein‐coupled receptor to inhibit the release of catecholamine from chromaffin cells. This action has no impact on Ca2+ levels and is similar for Ca2+ entry through voltage‐gated Ca2 channels and for Ca2+ mobilization from the endoplasmic reticulum.

Structure mirroring function: What's the ‘matter’ with the funny current?

The Journal of Physiology, EarlyView.
Abstract figure legend The ‘funny’ (If) current of cardiac pacemaker cells has been first identified in the late 1970s as a major mechanism in the generation and control of cardiac pacemaking. Decades of studies have since described the properties of the funny current and of its molecular components, HCN channels, in the heart and brain, providing the ...

Catecholaminergic polymorphic ventricular tachycardia–linked ryanodine receptor variants exhibit domain‐specific calcium leak and calmodulin affinity properties

The Journal of Physiology, EarlyView.
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

GATA Transcription Factors: A Cross‐Road for Erythropoiesis, Neurodevelopment, and Synucleinopathies

Developmental Neurobiology, Volume 85, Issue 3, July 2025.
ABSTRACT Alpha‐synuclein (α‐syn), a 140 amino acid protein, is abundantly expressed in the central nervous system (CNS) and in the erythrocytes, playing a pivotal role in the pathogenesis of Parkinson's disease (PD) and other synucleinopathies.
