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

open access: yesThe 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 ...

Two‐Pore K+ Channel TREK‐1 Regulates Sinoatrial Node Membrane Excitability

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundTwo‐pore K+ channels have emerged as potential targets to selectively regulate cardiac cell membrane excitability; however, lack of specific inhibitors and relevant animal models has impeded the effort to understand the role of 2‐pore K ...

Robust activity‐dependent mitochondrial calcium dynamics at the AIS is dispensable for action potential generation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In cortical layer (L)5 pyramidal neurons we found that mitochondria in the axon initial segment (AIS) are distributed non‐uniformly and display robust calcium (Ca2+) uptake during action potential (AP) firing. Because the AIS is the site for the initiation of APs, which are shaped by cytosolic Ca2+ levels, we hypothesized that ...

Life cycle-dependent cytoskeletal modifications in Plasmodium falciparum infected erythrocytes. [PDF]

open access: yesPLoS ONE, 2013
Plasmodium falciparum infection of human erythrocytes is known to result in the modification of the host cell cytoskeleton by parasite-coded proteins. However, such modifications and corresponding implications in malaria pathogenesis have not been fully ...

Membrane and Protein Interactions of the Pleckstrin Homology Domain Superfamily. [PDF]

open access: yes, 2015
The human genome encodes about 285 proteins that contain at least one annotated pleckstrin homology (PH) domain. As the first phosphoinositide binding module domain to be discovered, the PH domain recruits diverse protein architectures to cellular ...

Acquired Elliptocytosis as a Manifestation of Myelodysplastic Syndrome with Ring Sideroblasts and Multilineage Dysplasia. [PDF]

open access: yes, 2017
Acquired elliptocytosis is a known but rarely described abnormality in the myelodysplastic syndromes (MDS). Here we report the case of an elderly male who was admitted to the hospital with chest pain, dyspnea, and fatigue and was found to be anemic with ...

Neuronal Activity Promotes Node‐Like Cluster Assembly Prior to Myelination and Remyelination in the Central Nervous System

open access: yesGlia, Volume 74, Issue 4, April 2026.
Ronzano et al. show that neuronal activity promotes node‐like cluster (NLC) formation before (re)myelination by regulating β1Nav and Nav1.1, which are essential for NLC assembly. This may represent an intermediate step in activity‐driven myelination and contribute to the regulation of axonal conduction.

Bridging the computational gap between mesoscopic and continuum modeling of red blood cells for fully resolved blood flow

open access: yes, 2019
We present a computational framework for the simulation of blood flow with fully resolved red blood cells (RBCs) using a modular approach that consists of a lattice Boltzmann solver for the blood plasma, a novel finite element based solver for the ...

Plasmodium falciparum infection induces dynamic changes in the erythrocyte phospho-proteome [PDF]

open access: yes, 2016
The phosphorylation status of red blood cell proteins is strongly altered during the infection by the malaria parasite Plasmodium falciparum. We identify the key phosphorylation events that occur in the erythrocyte membrane and cytoskeleton during ...
