Professor Tom Carter

Professor of Endothelial Cell Biology
I am a Professor of Cell Biology within the Molecular & Cellular Sciences Research Section
Neuroscience & Cell Biology Research Institute

Professor Tom Carter’s research is aimed at identifying the molecular mechanisms that control the regulated secretion of coagulant and inflammatory mediators from vascular endothelial cells.

Tom Carter graduated from King's College London in 1986 with a joint honors degree in Physiology and Pharmacology and then carried out research for a PhD in Pharmacology in the group of Professor Jeremy Pearson in the Vascular Biology Unit of the MRC Clinical Research Center in Harrow, London.

His PhD work established a crucial role for intracellular calcium as the major trigger for the synthesis of prostacyclin (a potent vasodilator and anti-platelet mediator) during purinoceptor-activation in human endothelial cells. In 1989 he moved to the laboratory of Dr David Ogden in the Division of Neurophysiology at the MRC National Institute for Medical Research (NIMR) to learn and apply whole cell patch clamp, fluorescence photometry and flash photolysis techniques. Here he studied the mechanisms that underlie the generation of hormone-evoked calcium signals in endothelial cells and established the use of novel caged nitric oxide donors for the quantitative investigation of nitric oxide action in vascular tissues.

In 1995 he was awarded a British Heart Foundation Gerry Turner Fellowship and in 1998 a British Heart Foundation Basic University Lectureship. In 1998 he moved from the NIMR to join the Pharmacology Department at University College London as a lecturer and an honorary lecturer in Clinical Pharmacology. In 2003, he returned to NIMR, to take up a Career Scientist position within the Division of Molecular Neuroendocrinology where he concentrated on developing and applying new tools for high resolution, high speed, multicolour imaging of the intracellular trafficking and exocytosis of individual secretory granules in living endothelial cells.

In 2009 he became Acting Head of the Division of Molecular Neuroendocrinology and in 2010 became a Principle Investigator in the Division of Physical Biochemistry at NIMR. In October 2013 he joined the Division of Biomedical Sciences at St George's University of London as Professor of Endothelial Cell Biology. In 2016 he became head of the Cell Biology & Genetics research center at St George's University, and was elected a Fellow of the Royal Society of Biology (FRSB).

Professor Tom Carter’s research is aimed at identifying the molecular mechanisms that control the regulated secretion of coagulant and inflammatory mediators from vascular endothelial cells.

Endothelial cells line the lumen of all blood vessels and together constitute one of the largest and most complex secretory organs in the body. Endothelial cells control vital physiological processes such as blood flow, blood clotting, inflammation, vessel growth and wound healing through the secretion of a variety of coagulant, inflammatory and angiogenic molecules. Endothelial cell dysfunction alters the balance of secreted molecules and increases the risk of hypertension, ischemia, stroke, heart attack, infection and cancer. The mechanisms controlling the synthesis, packaging, trafficking and secretion of molecules in endothelial cells represent targets for modifying endothelial cell function in health and disease. Professor Carter’s group’s goal is to understand how endothelial cells secrete mediators directly implicated in human health and disease under “normal” and “perturbed” conditions. A better understanding of the basic cellular processes by which endothelial cells function will translate into novel therapeutic agents for human medicine.

Professor Carter’s  current work focuses on the biology of Weibel-Palade bodies (WPBs), the main regulated secretory granule of endothelial cells. WPBs contain von Willebrand factor, a pro-coagulant and adhesive molecule that plays a vital role in haemostasis.

Professor Carter’s current work comprises three interrelated strands of research which address the following questions:

  1. How is the transport, exocytosis and recycling of WPBs in endothelial cells controlled and regulated?
  2. What are the structural changes in von Willebrand Factor and WPBs during granule maturation, export and secretion?
  3. How is WPB fusion pore opening and closing regulated and controlled?
