Introduction
I am investigating the role of TRP channels and store-operated Ca2+ entry (Stim1 and Orai1) in endothelial progenitor cells (EPCs) from both peripheral and umbilical cord blood. We are also studying the remodeling of the Ca2+ toolkit in EPCs from human cancer (kidney and breast) patients. Ca2+ channels might be a feasible target for both regenerative medicine and anti-cancer strategies. We use Ca2+ imaging and patch-clamp, Western Blotting and immunofluorescence, qRT-PCR and gene silencing.

Tumor diseases are unfortunately quick spreading, even though numerous studies are under way to improve early diagnosis and targeted treatments that take into account both the different characteristics associated with the various tumor types and the conditions of individual patients. In recent years, studies have focused on the role of ion channels...

Background Cardiac mesenchymal stromal cells (C-MSC) were recently shown to differentiate into adipocytes and myofibroblasts to promote the aberrant remodeling of cardiac tissue that characterizes arrhythmogenic cardiomyopathy (ACM). A calcium (Ca²⁺) signaling dysfunction, mainly demonstrated in mouse models, is recognized as a mechanism impacting...

Background: Platelets can support cancer progression via the release of microparticles and microvesicles that enhance the migratory behaviour of recipient cancer cells. We recently showed that platelet-derived extracellular vesicles (PEVs) stimulate migration and invasiveness in highly metastatic MDA-MB-231 cells by stimulating the phosphorylation...

Histamine is an inflammatory mediator that can be released from mast cells to induce airway remodeling and cause persistent airflow limitation in asthma. In addition to stimulating airway smooth muscle cell constriction and hyperplasia, histamine promotes pulmonary remodeling by inducing fibroblast proliferation, contraction, and migration. It has...

(1) Background: Store-operated Ca2+ entry (SOCE) drives the cytotoxic activity of cytotoxic T lymphocytes (CTLs) against cancer cells. However, SOCE can be enhanced in cancer cells due to an increase in the expression and/or function of its underlying molecular components, i.e., STIM1 and Orai1. Herein, we evaluated the SOCE expression and function...
Article
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant disorder that associates with nucleotide sequence variants in genes encoding sarcomere related proteins, and is recognized as the most common heritable cardiac diseases. Clinically, HCM can be extremely variable and this makes the diagnosis difficult until the development of serious or fata...

The mechanism whereby an increase in neuronal activity (NA) leads to a local elevation in cerebral blood flow to supply the active neurons with oxygen and nutrients and remove the catabolic waste has been termed neurovascular coupling (NVC). Although it has long been thought that the vasoactive mediators involved in NVC are generated by neurons and...

Nicotinic acid adenine dinucleotide phosphate (NAADP) is a newly discovered second messenger that gates two pore channels 1 (TPC1) and 2 (TPC2) to elicit endo-lysosomal (EL) Ca2+ release. NAADP-induced lysosomal Ca2+ release may be amplified by the endoplasmic reticulum (ER) through the Ca2+-induced Ca2+ release (CICR) mechanism. NAADP-induced intr...

An increase in intracellular Ca2+ concentration ([Ca2+]i) controls virtually all endothelial cell functions and is, therefore, crucial to maintain cardiovascular homeostasis. An aberrant elevation in endothelial can indeed lead to severe cardiovascular disorders. Likewise, moderate amounts of reactive oxygen species (ROS) induce intracellular Ca2+...

During myocardial ischemia, timely reperfusion is critical to limit infarct area and the overall loss of cardiac contractile function. However, reperfusion further exacerbates the damage of the ischemic heart. This type of injury is known as ischemia-reperfusion injury (IRI). Ischemic conditioning is a procedure which consists of brief cycles of is...

The cerebellar granule cells (GrCs) are classically described as a homogeneous neuronal population discharging regularly without adaptation. We show that GrCs in fact generate diverse response patterns to current injection and synaptic activation, ranging from adap- tation to acceleration of firing. Adaptation was predicted by parameter optimizatio...
