Functional Role of Piezo1 in Regulating Whole‐Lung Vascular Reactivity

Pulmonary Circulation, Volume 16, Issue 3, July 2026.
ABSTRACT Mechanosensitive cation channels expressed in pulmonary arterial smooth muscle (SMC) and endothelial (EC) cells contribute to the regulation of vasoconstriction and vasodilation of the pulmonary vasculature. Here, we report that activating Piezo1, a mechanosensitive cation channel, with Yoda1 induced a mild increase in pulmonary arterial ...

Regulation of membrane ruffling by polarized STIM1 and ORAI1 in cortactin-rich domains

Scientific Reports, 2017
Cell motility and migration requires the reorganization of the cortical cytoskeleton at the leading edge of cells and extracellular Ca2+ entry is essential for this reorganization. However the molecular nature of the regulators of this pathway is unknown.

The Molecular Diagnosis of Myopathies: Integrating Genomic, Proteomic, and Pathological Insights Toward Precision Medicine

Clinical Genetics, Volume 110, Issue 1, Page 15-28, July 2026.
Advances in genomic, proteomic, and transcriptomic technologies are transforming the diagnosis of genetic myopathies. When integrated with traditional muscle pathology, multi‐omics approaches improve diagnostic yield, clarify disease mechanisms, and support more precise, mechanism‐based therapeutic strategies for patients with neuromuscular disorders ...

Endoplasmic Reticulum Geometry Dictates Neuronal Bursting via Calcium Store Refill Rates and Exposes Selective Neuronal Vulnerability

Advanced Science, Volume 13, Issue 36, 29 June 2026.
The ER's continuous tubular network is maintained by ER‐shaping proteins whose mutation or dysregulation contributes to neurodegenerative diseases. Here, we show that ER morphology sets the speed of Ca2+ store replenishment between firing events. Disrupting ER continuity slows intra‐ER Ca2+ redistribution from extracellular refill (SOCE) sites, driving

Sphingomyelin, ORAI1 channels, and cellular Ca2+ signaling [PDF]

Journal of General Physiology, 2015
An immunologist, asked to connect sphingomyelin and T lymphocyte signaling, would likely think first of the sphingomyelin metabolite sphingosine-1-phosphate. That thought is understandable in light of the rapid progress that has been made in studies of sphingosine-1-phosphate signaling and its ...

Ryanodine Receptor Ca2+ Leak‐Induced Redistribution of Ca2+ in Dystrophic mdx Mouse Muscle

Acta Physiologica, Volume 242, Issue 6, June 2026.
ABSTRACT Aim The dystrophic mdx mouse is a widely used model of Duchenne muscular dystrophy. Altered Ca2+ handling is a key feature, including increased Ca2+ leak through the ryanodine receptor (RyR1's), the primary Ca2+ release channel in skeletal muscle. Such leak has important downstream consequences for intracellular Ca2+ homeostasis.

Calcium Buffering in Astrocytes and Its Relevance for Experimental Data Interpretation and Computational Modeling

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.
Components and properties of Ca2+ buffers in astrocytes, which should be considered for data interpretation and in computational modeling of astrocyte Ca2+ activity. ABSTRACT Astrocytic Ca2+ signaling is essential for maintaining physiological brain function, including the modulation of synaptic transmission, neurovascular coupling, and ion homeostasis.
