Session 1: Intracellular Ca2+ Stores [8:30 ～ 10:25]
- Andrew Marks
- (Columbia University, USA)
- Andrew R. Marks, MD, was born February 22, 1955 in New York City. He received his undergraduate degree from Amherst College in 1976 where he was the first student in the history of the college to graduate with honors in two subjects (Biology and English), and his MD from Harvard Medical School in 1980. Following an internship and residency in internal medicine at the Massachusetts General Hospital (MGH), he was a post-doctoral fellow in molecular genetics at Harvard Medical School, and then a clinical cardiology fellow at the MGH. He is board certified in internal medicine and in cardiology. Dr. Marks is Chair and Professor of the Physiology and Cellular Biophysics Department at Columbia University. From 2002-2007 Dr. Marks was Editor-in-Chief of the Journal of Clinical Investigation. His honors include: ASCI (1995) AAP, the Institute of Medicine of the National Academies, American Academy of Arts and Sciences and the National Academy of Sciences. Doctor of Science Honoris Causa from Amherst College (2009), Docteur Honoris causa, del’Université de Montpellier (2016), the ASCI Stanley J. Korsmeyer Award (2010), the Pasarow Foundation Award for Cardiovascular Research (2011) and the Ellison Medical Foundation Senior Scholar in Aging Award (2011), Glorney-Raisbeck Award from NY Academy of Medicine (2016). In 2015 Dr. Marks was chosen to present the Ulf von Euler lecture at the Karolinska Institute. Dr. Marks’ identification of the mechanism of action of rapamycin’s inhibition of vascular smooth muscle proliferation and migration lead to the development of the first drug-eluting stent (coated with rapamycin) for treatment of coronary artery disease. This substantially reduced the incidence of instent restenosis. In 2014 Dr. Marks reported the high resolution structure of the mammalian type 1 ryanodine receptor/calcium release channel (required for excitation-contraction coupling in skeletal muscle) which he had cloned and work on since 1989. His work has contributed new understandings of fundamental mechanisms that control muscle contraction, lymphocyte activation, and cognitive function. He discovered that “leaky” intracellular calcium release channels (ryanodine receptors) contribute to heart failure, fatal cardiac arrhythmias, and impaired exercise capacity particularly in muscular dystrophy, post-traumatic stress disorder (PTSD) and Alzheimer’s Disease. Dr. Marks discovered a new class of small molecules (Rycals), developed in his laboratory, that target leaky ryanodine receptor channels and effectively treat cardiac arrhythmias, heart failure, muscular dystrophy and prevent stress induced cognitive dysfunction in pre-clinical studies. Rycals are now in Phase II clinical trials for the treatment of heart failure and cardiac arrhythmias, and entering clinical trials for the treatment of Duchenne Muscular Dystrophy.
- David Yule
- (University of Rochester, USA)
- David I. Yule. PhD. University of Liverpool, UK. (1990). Fellow, University of Michigan, USA (1990-1998) Professor of Pharmacology and Physiology, University of Rochester, USA (1998-present). Over the past 20 years, the focus of my research has been to gain a better understanding of how intracellular free Ca2+, a ubiquitous second messenger, can control a multitude of cellular processes with precise specificity and fidelity. In particular, my lab has investigated the mechanisms, which underlie Ca2+ signaling events and their downstream effectors necessary for proper exocrine function in pancreatic and salivary acinar cells. A particular focus of the laboratory is investigating the properties and regulation of Inositol 1,4,5-trisphosphate receptors, the primary Ca2+ release mechanisms in many cell types. This knowledge is important because it is increasing clear that dysregulation of normal signaling is a common occurrence in pathological states of many organ systems. Our primary approaches involve imaging techniques including multi-photon, confocal and TIRF microscopy complemented by single channel and whole-cell patch clamp electrophysiology. Throughout the past 15 years we have complemented this experimental work by using a computation and modeling systems biology based approach through a collaboration with Dr. James Sneyd at the University of Auckland, NZ.
- Sandip Patel
- (University College London, UK)
- Sandip Patel obtained his PhD under the supervision of Colin W. Taylor (Cambridge, 1995). He did post-doctoral work with Andrew P. Thomas (USA, 1996-1999) and Antony Galione (Oxford, 1999). Sandip started his own lab in 2000 in Oxford through a Wellcome Trust Career Development Fellowship which he re-located to its present location at University College London in 2001. He was promoted to Professor in 2011.
Sandip was Vice-chair of the Signalling Panel of the Biochemical Society (2009-2012) and currently a member of the Grants advisory panel of Parkinson’s UK (2016-). He is an Associate Editor of Messenger (2012-) and a member of the Editorial boards of Biology of the Cell (2003-2006), the Biochemical Journal (2004-2011) and Cell Calcium (2007-).
He was elected a Fellow of the Royal Society of Biology (FRSB) in 2013.
- Roberto Docampo
- (University of Georgia, USA)
- Prof. Roberto Docampo graduate work at the University of Buenos Aires (1976-1979) revealed the role of free radicals in the mechanism of action and toxicity of antiparasitic drugs. During his postdoc work at the NIH (1982-1986), Docampo discovered the first and only example of a biochemical reaction (pyruvate-ferredoxin oxidoreductase) in which two free radicals, a carbon-centered free radical derived from pyruvate and a thyil radical derived from CoA, combine to form a high-energy compound (acetyl-CoA). When a Visiting Professor at the Federal University of Rio de Janeiro (1986-1988), his lab found that Trypanosoma cruzi, the agent of Chagas disease, possesses a mitochondrial calcium uniporter of similar characteristics to those of the mammalian uniporter, a finding that was fundamental for the recent discovery of the gene encoding this uniporter in eukaryotes. When a Professor at the University of Illinois at Urbana-Champaign (1990-2004) his lab discovered and characterized the acidocalcisome, an acidic calcium store rich in polyphosphate that is the only organelle conserved from bacteria to mammalian cells. The finding of similar acidocalcisome-like organelles rich in polyphosphate in human platelets (dense granules) led to his lab discovery of the role of this polymer as a procoagulant and antifibrinolytic agent, and the further discovery of its role in inflammation and thrombosis. His lab also discovered the antiparasitic action of pyrophosphate analogs (bisphosphonates), some of which had curative effects on experimental trypanosomiasis. He moved to the University of Georgia in 2005, where he further characterized the composition and functions of acidocalcisomes, their presence in mast cells, human basophils, and insect eggs, and their interaction with other organelles, such as mitochondria and the contractile vacuole. His lab discovered a role of the contractile vacuole of T. cruzi in trafficking proteins to the plasma membrane and acidocalcisomes. His most recent work at UGA was the first successful development of the CRISPR/Cas9 technique for genome editing (gene knockout and gene tagging) of these parasites and the characterization of their calcium signaling pathways. He is the Editor-in-Chief of the Journal of Eukaryotic Microbiology, and member of the Editorial Boards of several journals. He is the principal investigator on three major research grants (R0ls) from the National Institutes of Health. For his scientific contributions, he was recognized as Fellow of the American Academy of Microbiology, and the American Association for the Advancement of Science, and as corresponding member of the Brazilian Academy of Sciences, and the Latin American Academy of Sciences. He was also recognized as Doctor Honoris Causa of the University of San Martin, Argentina

- Axel Nimmerjahn
- (Salk Institute, USA)
- Axel Nimmerjahn received his Ph.D. in physics in the laboratories of Fritjof Helmchen and Bert Sakmann at the Max Planck Institute for Medical Research and the University of Heidelberg, Germany. Following postdoctoral training with Mark J. Schnitzer and Ben A. Barres in the Departments of Biology and Applied Physics at Stanford University, USA, he joined the Waitt Advanced Biophotonics Center at the Salk Institute for Biological Studies, USA, as an assistant professor. As of 2017, he is an associate professor at the same institution.
Dr. Nimmerjahn’s research focuses on elucidating the role of glial cells in protecting and maintaining mammalian central nervous system (CNS) function. To study glia he and his team have developed novel in vivo imaging, staining, molecular genetic, behavioral and computational methods. This has allowed them to provide the first study of microglia’s immune surveillance dynamics in the intact healthy and injured brain. They showed that microglial branch motility and convergence to sites of blood-brain barrier disruption depends on the TAM receptor tyrosine kinases Mer and Axl. They further demonstrated that TAM receptors play crucial roles in the removal of virus-transduced and newborn cells, and they identified mechanisms through which the viral innate immune response by microglia can be controlled. Through development of two- and miniaturized one-photon microscopes, and the discovery of sulforhodamine 101 as a glial marker, they provided the first study of astrocyte calcium excitation in the brain and spinal cord of behaving animals. This revealed that astrocytes exhibit distinct forms of neural activity-dependent and -independent calcium excitation. In particular, they showed that behavioral transitions in the brain and nociceptive signaling in the spinal cord can evoke millimeter-scale excitation in astrocyte networks, placing these cells in a position to initiate macroscopic changes in CNS dynamics.
Dr. Nimmerjahn’s work has been recognized by a variety of awards, including the Du Bois-Reymond Award of the German Physiologic Society, Otto Hahn Medal and Award of the Max Planck Society, a Rita Allen Foundation Scholar Award, and New Innovator and EUREKA Awards by the National Institutes of Health.

- Thomas Simmen
- (University of Alberta, USA)
- My laboratory focuses on the characterization of connections between the endoplasmic reticulum (ER) and mitochondria and their role in disease. We are interested in understanding how mitochondria influence ER homeostasis and how ER stress triggers ER-mitochondria calcium exchange and eventually apoptosis. We examine why tumor cells often are defective for these signaling mechanisms, resulting in the excessive toxin production by tumor cells that would normally trigger apoptosis, but which fail to do so in a cancer setting. Additionally, we examine the significance of the MAM in neuroinflammation. Since its start-up in 2005, our laboratory has been awarded with an operating grant from the Canadian Institutes of Health Research (CIHR), 2 operating grants from the Canadian Cancer Society Research Institute (CCSRI) and the National Science and Engineering Research Council (NSERC) each, one Canadian Breast Cancer Foundation (CBCF) operating grant and one Cancer Research Society (CRS) grant, among others.

as an adolescent, for a number of Summers I hitchhiked across war-ravaged Europe as an hitchhiker. Well into middle age I kept climbing mountains, mostly in the rocky Dolomites. Poetry and art, including music, have been my main intellectual non scientific lifelong interests.
When I entered Medical School at the University of Modena I had in mind to become a practicing Doctor, following the footsteps of my father and grandfather. But I soon shifted my interests toward science: which in this case was bioenergetics, as the Institute in which I was working as an internal student was one of the first to work on mitochondria in Italy. And so, after graduation and a brief stint in psychiatry, I ended up as a postdoc in the Laboratory of Albert L. Lehninger at Johns Hopkins. There, the transport of calcium by mitochondria had just been discovered, and Lehninger recommended it to me as the topic of work. It was a turning point in my life, as calcium was to remain my lifelong companion. Our work at at Johns Hopkins on mitochondrial calcium transport provided fundamental support for the revolutionary chemiosmotic theory of Peter Mitchell. After my return to Europe and my appointment at the ETH in Zurich I gradually shifted my interests away from mitochondria, and started working on the calcium transporting ATPase of the plasma membrane. We have worked on it for over three decades, providing fundamental information on the properties and the ATPase and its role in the regulation of cellular calcium signaling. In 2001, having reached retirement age at the ETH in Zurich, I moved back to Padova as a Professor of Biochemistry: two years later, I co-founded the Venetian Institute if Molecular Medicine (VIMM) , where I presently work. In the last ten years or so at the VIMM I have gradually extended my interests to the pathological deviations of the process of calcium signaling, particularly to the genetic mutations of the plasma membrane calcium ATPases in neuronal pathologies.
Nishizuka Lecture [16:10 ～ 17:10]
- Anjana Rao
- (Lajolla Institute, USA)
- Dr. Anjana Rao obtained her Ph.D. in Biophysics from Harvard University and was a Professor at Harvard Medical School until 2010, when she moved to the La Jolla Institute and UCSD (University of California in San Diego). Her research is focused on the regulation of gene expression, using primarily immune cells as a model system. Her lab purified and molecularly characterized the calcium/ calcineurin-regulated transcription factor NFAT; defined diverse transcriptional programs regulated by NFAT proteins in T cells; identified the pore subunit of the store-operated Ca2+ channel, ORAI1; and discovered that proteins of the TET family are enzymes that alter DNA methylation status and regulate gene expression by oxidizing 5-methylcytosine. In recent studies, she has defined the role of NFAT in the hyporesponsive state termed exhaustion in tumor-infiltrating T cells, and explored the roles of TET proteins and oxidized methylcytosines in the immune, haematopoietic and nervous systems as well as in embryonic development and oncogenesis. Dr. Rao has received numerous awards throughout her career.

- Murali Prakriya
- (Northwestern University, USA)
- Murali Prakriya is a Professor of Pharmacology, Northwestern University, Chicago, USA. His research examines the mechanisms and functions of store-operated calcium channels (SOCs). SOCs are expressed in most animal cells and regulate diverse cellular functions ranging from gene expression, motility and secretion to tissue and organ development, and the immune response. The best-described SOCs are made of the Orai proteins, which form the calcium-selective pores of the channels, and are activated by the ER calcium sensors, STIM1 and STIM2. Prakriya’s work examines the biophysical and structural mechanisms of Orai channel gating, and their physiological roles in neurons, glia, and immune cells.

- POSITION TITLE
Professor and Chair, Department of Cellular and Molecular Physiology The Pennsylvania State University College of Medicine
My lab has been studying the molecular mechanisms mediating Ca2+ signals for the last 30 years. We have de-fined many novel parameters of the structure, function and control of the Ca2+ signaling machinery, focusing on smooth muscle and immune cell models to understand the extraordinary molecular cross-talk and functional integration that exists between Ca2+ sensors and Ca2+ channel proteins. My lab has maintained two complemen-tary research projects for many years, one on Ca2+ signaling by STIM proteins in smooth muscle (GM 109279), and the other on control of Orai Ca2+ entry channels in B cells (GM 120783). In recent years, we have focused on the ubiquitously expressed STIM and Orai proteins that mediate essential but quite distinct Ca2+ signals in these two cell types. The MIRA application is an opportunity to combine these studies into a comprehensive program to understand the fundamental “coupling interface” between the STIM protein ER Ca2+ sensors and the ubiquitously expressed Orai family of highly Ca2+-selective Ca2+ entry channels. This tightly regulated STIM-Orai coupling process functions to mediate and integrate Ca2+ signals crucial in controlling transcription, proliferation, motility, and growth remodeling, with broad implications for all cell types.
Over the last 20 years, my lab has maintained a leading role in understanding how “store-operated” Ca2+ signals are generated and how the STIM-Orai Ca2+ signaling pathway operates. Our initial work revealed the process involves reversible ER-PM junctional interactions. Subsequently, we designed the screen used to first identify STIM proteins, and revealed that STIM and Orai proteins reconstitute the authentic Ca2+ release-activated Ca2+ (CRAC) current, the classical hall-mark of store-operated Ca2+ entry (SOCE) in all cells. More recently, we developed a spectrum of molecular probes and cell imaging approaches with which we have mapped the molecular interactions, dynamics and mechanism of the STIM-Orai coupling pathway. These studies utilize a combination of high-resolution imaging technology, real-time FRET analyses, functional channel studies, protein structural analyses, CRISPR/Cas9 gene editing approaches, and design of a spectrum of genetically-encoded single molecule and concatenated molecular probes. Our probes and reagents are rigorously authenticated and key studies are controlled and blinded to avoid misinterpretation or bias. We share our probes and assist others in their use and interpretation; we present findings widely at meetings including the highly subscribed Calcium Signaling Gordon Research Conference I founded in 1993.
This cadre of tools and approaches has allowed my lab to make some critical advances over the last three years that provide an important basis for the MIRA-supported studies we propose. These advances (refs 1-4) fundamentally change our understanding of the STIM-Orai signaling pathway, revealing: (1) the crucial locus on STIM proteins for Orai channel interaction which defines important functional distinctions between STIM1 and STIM2; (2) that the dimeric STIM proteins undergo a surprising unimolecular coupling interaction with Orai channel subunits with important implications for channel cross-talk and clustering; (3) that the Orai1 channel functions as a hexamer (not a tetramer as widely reported) ; (4) that gating of Orai channels is mediated by a remote STIM-induced allosteric control mechanism and not a direct pore-displacement mechanism suggested earlier. The studies proposed build upon this new base of information to determine: (a) how the STIM protein subtypes activate and unfold to interact with Orai channels, (b) what constitutes the molecular basis of STIM-binding to the Orai channel subtypes and how this binding is transduced into channel gating, and (c) how the spatially organized STIM-Orai complexes formed within ER-PM junctions generate coded oscillatory Ca2+ signals to control transcription factor activation and altered growth phenotype.
As Chair of the Department of Cellular and Molecular Physiology at Penn State University College of Medicine, we have assembled a highly interactive group of cellular signaling investigators. We have developed some important collaborations in our study of STIM and Orai proteins. There are three Key Personnel associated with the MIRA project: (a) Dr. Yandong Zhou has worked in my lab for several years and is an extraordinarily talented expert in FRET imaging, super-resolution imaging, electrophysiology, and designing our tagged/ concatenated probes; (b) My lab now works closely with the lab of Dr. Mo Trebak who joined the Department in 2015. His direction is toward translational understanding of the role of Ca2+ entry channels (TRP, Orai and CaV subtypes) in endothelial cell function, and changes during vascular and pulmonary remodeling; (c) We undertake NMR structural analysis on STIM and Orai fragments with Dr. Fang Tian, in the Department of Biochemistry here at Hershey. Penn State is investing in two FEI Krios Cryo-EM transmission electron microscopes, and in collaboration with Dr. Susan Hafenstein (Penn State) and Dr. Vera Moiseenkova-Bell (Case Western), we are using the molecular constructs we have developed to solve structures of the STIM1-Orai1 complex and the Orai1 open channel. In the last 2 years we initiated an important collaboration with Dr. Barbara Niemeyer in Homburg, on the function of the STIM2.1 splice variant of STIM2. This is crucial work in the MIRA project and she has helped us much with examining its expression and allowing us to make dimer constructs of SOAR2.1. We also share resources with another recent Department recruit, Dr. Shengyu Yang, a cancer cell biologist studying the role of Orai channels and actin-bundling proteins in metastatic progression and the invasive properties of melanoma cells. We also have a strong collaboration with Dr. Michael Cahalan at UC Irvine, on analysis of the nature of the ER-PM junctional complex and visualization of the organization of STIM and Orai channels into clusters within the junction.
My lab will continue to train new researchers: I have mentored 15 Ph.D. students, and 21 postdoctoral fellows, and served as Graduate Program Director at U. Maryland for 12 years. At Hershey, we built the new Cellular and Integrative Physiology training program that interfaces with the strong Biomedical Sciences Program.
