The Open University

Professional biography

I am a cell physiologist specialising in calcium signalling and the regulation of calcium channels. My PhD was obtained in the laboratory of Bernd Walz at the University of Potsdam in Germany on the topic of ‘Signalling Pathways that Stimulate Protein and Fluid Secretion in Cockroach Salivary Glands’. This was followed by studying IP₃ receptor-interacting proteins in Martin Bootman and Mike Berridge’s laboratory at The Babraham Institute in Cambridge, and the characterisation of two-pore channels (TPCs) as endolysosomal calcium channels activated by the second messenger NAADP in Antony Galione’s laboratory at Oxford University. Subsequently I joined the laboratory of Michael Sanderson at UMASS Medical School in Worcester, MA, USA and started working on a special type of cardiac cells called pulmonary vein sleeve cells (PVCs). From UMASS I moved to The Open University, first as a Research Fellow, before I became a Lecturer in Biology in 2016.

Research interests

My research focusses on the role of calcium signalling in health and disease, especially in cardiac cells. Much of my work has focussed on the regulation of intracellular calcium release channels, namely IP₃ receptors and ryanodine receptors localised on the endo- or sarcoplasmic reticulum, and two-pore channels (TPCs) on endosomes and lysosomes. All the projects are done in close collaboration with Martin Bootman.

Over the past years, we have worked on a pro-arrhythmic type of cardiac myocyte that is located in the pulmonary vein, called pulmonary vein sleeve cells (PVCs). The spontaneous activity of these cells is one of the main causes of atrial fibrillation, the most common form of cardiac arrhythmia. In one of our projects, we are characterising the structural and functional changes that occur in PVCs during ageing.

Based on my interest in endolysosomal ion channels, especially TPCs, and the fact that recent work provided evidence that the activity of TPCs can modulate the function of cardiac myocytes, we are studying how lysosomal ion channels contribute to the function of healthy cardiac myocytes.

Patients suffering from a lysosomal storage disorder called CLN3 develop cardiac dysfunction during their disease progression. CLN3 belongs to a group of lysosomal storage disorders called Neuronal Ceroid Lipofuscinoses (NCLs). To study what causes the decline in the cardiac function observed in CLN3 patients, we are comparing the structure and function of iPSC-derived cardiac myocytes using cells from patients with and without mutations in the CLN3 gene.

Other projects in the laboratory study the role of calcium in autophagy, and mechanisms of vascular calcification caused by calcium-phosphate particles.

Altered calcium homeostasis in Crohn's Disease

Role	Start date	End date	Funding source
Co-investigator	01 Oct 2015	30 Sep 2019	Fraser McDonald;MRC Human Nutrition Research (MRC HNR)
This is a collaborative project with the MRC Human Nutrition Research Unit in Cambridge. They have a long-standing interest in understanding how peptidoglycans released by bacteria in the gut lead to dampening of immune responses. The current hypothesis suggests that the peptidoglycans are transported across the gut wall through specialized uptake cells because they are encased in a calcium-phosphate matrix. Following their transport across the gut wall, the peptidoglycan/calcium-phosphate nanoparticles are endocytosed by white blood cells that consequently express a death receptor ligand. This study will investigate the role of the mineral component of the peptidoglycan/calcium-phosphate nanoparticles, and examine whether Crohn's patients have a different response to normal, in that they cannot process the calcium deposit and it leads to abnormal cell function.

Characterising The Response Of Foamy Alveolar Macrophages To Inhaled Drug Particulates - Phase II

Role	Start date	End date	Funding source
Co-investigator	16 Jan 2015	15 Jan 2018	NC3Rs (National Centre for the Replacement Refinement and Reduction of Animals in Research)
Lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) affect the lives of millions of people in the UK. Whilst the number of patients diagnosed with lung disease increases each year, the treatments available have changed very little over the past 30 years, despite large investment from pharmaceutical companies for the development of new treatments. One of the main reasons that many new medicines have not reached the market is the limited understanding of how the immune system in the lungs responds to the inhalation of therapeutic drug powders. Additionally, current methods used to test the safety of new inhaled medicines, rely on animal models which may not accurately predict safety in humans. Regulatory bodies are therefore unable to approve new medicines that appear to sensitise the immune system in animal models, despite not knowing fully if these observations are adverse in human patients. This project aims to better characterise inflammatory responses in the lung to inhaled medicines. Commercially available cell based models of the lung will be used, and imaging, biological and analytical tools will be employed to determine the reactions to inhaled medicines. The ultimate goal will be to use non-animal methods to provide an in depth understanding of the immune responses in the lung to reduce the numbers of animal experiments required to achieve an accurate prediction of the safety of new inhaled medicines in humans.
