David Alfred Eisner, FRCP (Hon), FMedSci, [2] (born 3 January 1955) [1] [3] is British Heart Foundation Professor of Cardiac Physiology at the University of Manchester and editor-in-chief of The Journal of General Physiology (JGP). [4]

Contents

Education

Eisner was born in 1955 in Manchester, the son of the physicist and writer Herbert Eisner. [5] [3] [6] After attending Manchester Grammar School, he received his B.A. in natural sciences at King's College, Cambridge in 1976. In 1979 he obtained a D.Phil. in physiology at Oxford University in the laboratory of Denis Noble for work on the sodium pump in cardiac muscle.

Career

Following postdoctoral research at the University of Cambridge on the kinetics of the sodium pump [7] in the laboratory of Ian Glynn, he took up a lectureship in the Department of Physiology at University College London in 1980. In 1990 he moved to The University of Liverpool as professor of veterinary biology. In 1999 he took up a chair of cardiac physiology at the University of Manchester and, in 2000, was awarded the BHF Chair of Cardiac Physiology. [8]

Eisner was chair of the editorial board of The Journal of Physiology from 1997 to 2000 [9] and editor-in chief of the Journal of Molecular and Cellular Cardiology from 2007 to 2016. He was president of The Federation of European Physiological Societies (FEPS) from 2011-2015 [10] and The Physiological Society from 2016 to 2018.

Research

Eisner's early research focused on the regulation of intracellular sodium in cardiac muscle and the effects on contraction. [11] He then investigated the control of intracellular calcium concentration [12] and its role in the production of arrhythmias. [13] He has identified the factors that regulate the calcium content of the sarcoplasmic reticulum [14] [15] and how this is altered in disease. [16] His recent research has focused on the control of diastolic calcium [17] [18] and the effects of calcium buffering. [19] [20] He has also written [21] and spoken [22] about scientific reproducibility and fraud.

Personal life

Eisner is married to Susan Wray, professor of cellular and molecular physiology at the University of Liverpool, with whom he has three children. [6]

Honours and awards

Eisner was elected as a Fellow of The Academy of Medical Sciences in 1999 [23] and The International Society for Heart Research in 2001. [24] and as a Member of Academia Europaea in 2007. [25] He was elected to Honorary Fellowship of The Royal College of Physicians in 2010. In 2018 he received an honorary doctorate, Doctor Honoris Causa, from The University of Debrecen. [26] and , in 2021 from The University of Szeged. [27] Prizes awarded to him include: The GL Brown [28] [29] and Annual Review Lecture [30] of The Physiological Society; the Keith Reimer Lecture [31] [32] and the Peter Harris Distinguished Scientist Award of the International Society for Heart Research; the Carmeliet-Coraboeuf-Weidmann Lecture of the European Working Group on Cardiac Cellular Electrophysiology; [33] the Fabio Ruzzier Lecture of The Italian Physiological Society. [34] He has also delivered the Burdon-Sanderson Lecture (Oxford) in 2013. [35]

<span class="mw-page-title-main">Sarcoplasmic reticulum</span> Menbrane-bound structure in muscle cells for storing calcium

The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+). Calcium ion levels are kept relatively constant, with the concentration of calcium ions within a cell being 10,000 times smaller than the concentration of calcium ions outside the cell. This means that small increases in calcium ions within the cell are easily detected and can bring about important cellular changes (the calcium is said to be a second messenger). Calcium is used to make calcium carbonate (found in chalk) and calcium phosphate, two compounds that the body uses to make teeth and bones. This means that too much calcium within the cells can lead to hardening (calcification) of certain intracellular structures, including the mitochondria, leading to cell death. Therefore, it is vital that calcium ion levels are controlled tightly, and can be released into the cell when necessary and then removed from the cell.

<span class="mw-page-title-main">Cardiac muscle</span> Muscular tissue of heart in vertebrates

Cardiac muscle is one of three types of vertebrate muscle tissues, with the other two being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart. The cardiac muscle (myocardium) forms a thick middle layer between the outer layer of the heart wall and the inner layer, with blood supplied via the coronary circulation. It is composed of individual cardiac muscle cells joined by intercalated discs, and encased by collagen fibers and other substances that form the extracellular matrix.

<span class="mw-page-title-main">Sinoatrial node</span> Group of cells located in the wall of the right atrium of the heart

The sinoatrial node is an oval shaped region of special cardiac muscle in the upper back wall of the right atrium made up of cells known as pacemaker cells. The sinus node is approximately 15 mm long, 3 mm wide, and 1 mm thick, located directly below and to the side of the superior vena cava.

<span class="mw-page-title-main">Frank–Starling law</span> Relationship between stroke volume and end diastolic volume

The Frank–Starling law of the heart represents the relationship between stroke volume and end diastolic volume. The law states that the stroke volume of the heart increases in response to an increase in the volume of blood in the ventricles, before contraction, when all other factors remain constant. As a larger volume of blood flows into the ventricle, the blood stretches cardiac muscle, leading to an increase in the force of contraction. The Frank-Starling mechanism allows the cardiac output to be synchronized with the venous return, arterial blood supply and humoral length, without depending upon external regulation to make alterations. The physiological importance of the mechanism lies mainly in maintaining left and right ventricular output equality.

<span class="mw-page-title-main">Cardiac action potential</span> Biological process in the heart

The cardiac action potential is a brief change in voltage across the cell membrane of heart cells. This is caused by the movement of charged atoms between the inside and outside of the cell, through proteins called ion channels. The cardiac action potential differs from action potentials found in other types of electrically excitable cells, such as nerves. Action potentials also vary within the heart; this is due to the presence of different ion channels in different cells.

<span class="mw-page-title-main">Muscle contraction</span> Activation of tension-generating sites in muscle

Muscle contraction is the activation of tension-generating sites within muscle cells. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.

<span class="mw-page-title-main">T-tubule</span> Extensions in cell membrane of muscle fibres

T-tubules are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells. With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration.

Sydney Ringer FRS was a British clinician, physiologist and pharmacologist, best known for inventing Ringer's solution. He was born in 1835 in Norwich, England and died following a stroke in 1910 in Lastingham, Yorkshire, England. His gravestone and some other records report 1835 for his birth, some census records and other documents suggest 1836, but his baptismal record at St Mary's Baptist Chapel confirms this was 1835.

The sodium-calcium exchanger (often denoted Na+/Ca2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na+) by allowing Na+ to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca2+). A single calcium ion is exported for the import of three sodium ions. The exchanger exists in many different cell types and animal species. The NCX is considered one of the most important cellular mechanisms for removing Ca2+.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an inherited genetic disorder that predisposes those affected to potentially life-threatening abnormal heart rhythms or arrhythmias. The arrhythmias seen in CPVT typically occur during exercise or at times of emotional stress, and classically take the form of bidirectional ventricular tachycardia or ventricular fibrillation. Those affected may be asymptomatic, but they may also experience blackouts or even sudden cardiac death.

The Bowditch effect, also known as the Treppe phenomenon and the Treppe effect, is an autoregulation method by which myocardial tension increases with an increase in heart rate. It was first observed by Henry Pickering Bowditch in 1871.

The Anrep effect is an autoregulation method in which myocardial contractility increases with afterload. It was experimentally determined that increasing afterload caused a proportional linear increase in ventricular inotropy. This effect is found in denervated heart preparations, such as the Starling Preparation, and represents an intrinsic autoregulation mechanism.

Calcium buffering describes the processes which help stabilise the concentration of free calcium ions within cells, in a similar manner to how pH buffers maintain a stable concentration of hydrogen ions. The majority of calcium ions within the cell are bound to intracellular proteins, leaving a minority freely dissociated. When calcium is added to or removed from the cytoplasm by transport across the cell membrane or sarcoplasmic reticulum, calcium buffers minimise the effect on changes in cytoplasmic free calcium concentration by binding calcium to or releasing calcium from intracellular proteins. As a result, 99% of the calcium added to the cytosol of a cardiomyocyte during each cardiac cycle becomes bound to calcium buffers, creating a relatively small change in free calcium.
