Mechanism of Platelet Granule Release and its Role in Thrombus Formation: Lead Contributor to discoveries, Robert Flaumenhaft, MD, PhD, Division of Hemostasis and Thrombosis at BIDMC and Harvard Medical School

Reporter: Aviva Lev-Ari, PhD, RN

 

It is well known that platelets are crucial for stopping bleeding. Platelets prevent excessive posttraumatic blood loss at sites of vascular injury by forming a platelet plug. Upon exposure of the subendothelial extracellular matrix, platelets are recruited to the site of injury and become activated, resulting in firm adhesion and subsequent platelet aggregation. The molecular mechanisms underlying the formation of a hemostatic platelet plug are relatively well understood: upon exposure of the subendothelial matrix, platelets either interact directly with matrix proteins (eg, via glycoprotein VI [GPVI] and α2β1 to collagen) or bind to von Willebrand factor (VWF) that is deposited at the site of injury. Transient interactions between platelet GPIb and VWF support platelet tethering at sites of high shear stress. Firm adhesion and subsequent aggregation is mediated by activated integrin receptors such as αIIbβ3. G-protein–coupled receptors mediate activation signals after being triggered by soluble agonists such as thrombin, thromboxane A2, and adenosine 5′-diphosphate, which reinforce thrombus propagation.

To address the role of platelet granule content in maintaining vascular integrity in inflammation, Deppermann et al generated Unc13d−/−/Nbeal2−/− mice.1 Platelets from these mice are unable to secrete their α- or dense-granule content. The authors used these mice in models of lung inflammation, skin inflammation, and brain infarction. Similar to previous studies, intradermal hemorrhage was observed in platelet-depleted wild-type (WT) mice at the site of inflammation. Strikingly, no bleeding was observed in the inflamed skin of Unc13d−/−/Nbeal2−/− mice. Analogous results were observed in lung inflammation. These experiments show that release of α or dense granules is not necessary to maintain vascular integrity at sites of acute inflammation in skin and lung. Much different results were however obtained in the stroke model used by the authors. Indeed, when subjected to transient middle cerebral artery occlusion, Unc13d−/−/Nbeal2−/− mice were prone to intracranial bleeding in the infarcted areas. Cerebral hemorrhage in these mice resulted in a significantly increased mortality compared with WT animals. In an elegant approach using platelet transfusion experiments, the authors showed that the observed effects of combined Munc13-4 and Nbeal deficiency were related to the platelet-specific secretion effects and not to potential defects in other cells.

Procoagulant platelets: generation, function, and therapeutic targeting in thrombosis

Ejaife O. Agbani and Alastair W. Poole
Blood 2017 130:2171-2179; doi: https://doi.org/10.1182/blood-2017-05-787259

Abstract

Current understanding of how platelets localize coagulation to wound sites has come mainly from studies of a subpopulation of activated platelets. In this review, we summarize data from the last 4 decades that have described these platelets with a range of descriptive titles and attributes. We identify striking overlaps in the reported characteristics of these platelets, which imply a single subpopulation of versatile platelets and thus suggest that their commonality requires unification of their description. We therefore propose the term procoagulant platelet as the unifying terminology. We discuss the agonist requirements and molecular drivers for the dramatic morphological transformation platelets undergo when becoming procoagulant. Finally, we provide perspectives on the biomarker potential of procoagulant platelets for thrombotic events as well as on the possible clinical benefits of inhibitors of carbonic anhydrase enzymes and the water channel Aquaporin-1 for targeting this subpopulation of platelets as antiprocoagulant antithrombotics.

Platelet alpha-granules: basic biology and clinical correlates.

Blair P1, Flaumenhaft R.

Abstract

alpha-Granules are essential to normal platelet activity. These unusual secretory granules derive their cargo from both regulated secretory and endocytotic pathways in megakaryocytes. Rare, inheritable defects of alpha-granule formation in mice and man have enabled identification of proteins that mediate cargo trafficking and alpha-granule formation. In platelets, alpha-granules fuse with the plasma membrane upon activation, releasing their cargo and increasing platelet surface area. The mechanisms that control alpha-granule membrane fusion have begun to be elucidated at the molecular level. SNAREs and SNARE accessory proteins that control alpha-granule secretion have been identified. Proteomic studies demonstrate that hundreds of bioactive proteins are released from alpha-granules. This breadth of proteins implies a versatile functionality. While initially known primarily for their participation in thrombosis and hemostasis, the role of alpha-granules in inflammation, atherosclerosis, antimicrobial host defense, wound healing, angiogenesis, and malignancy has become increasingly appreciated as the function of platelets in the pathophysiology of these processes has been defined. This review will consider the formation, release, and physiologic roles of alpha-granules with special emphasis on work performed over the last decade.

Newly Elect President of Technion, Professor Uri Sivan: Key Contributions to Scientific Innovations

 

Reporter: Aviva Lev-Ari, PhD, RN

 

February 7, 2019
By: Office of the Technion Spokesperson

The Technion Council, headed by Mr. Gideon Frank, has elected Professor Uri Sivan of the Faculty of Physics as the next president of Technion. The Council’s decision was based on the recommendation of the Search Committee for the Technion President and received sweeping support from the Academic Assembly. The appointment is subject to the final approval of the International Board of Governors, which is set to convene in June.

Professor Uri Sivan

Prof. Sivan will commence his term as President of Technion on October 1 2019, and will replace the outgoing President Prof. Peretz Lavie, who will complete his term after a decade in office.

Prof. Sivan, 64, a resident of Haifa, is married and the father of three. He served as a pilot in the Israeli Air Force. He has a BSc in Physics and Mathematics, an MSc and PhD in Physics, all with honors from Tel Aviv University.

In 1991, after three years at IBM’s T. J. Watson Research Center in New York, Prof. Sivan joined the Faculty of Physics at Technion.

Key Contributions to Scientific Innovations

  • His research has covered a wide range of fields including quantum mesoscopic physics and the harnessing of molecular and cellular biology for the self-assembly of miniature electronic devices. Prof. Sivan, along with colleagues Profs. Erez Braun and Yoav Eichen, demonstrated for the first time how to harness molecular recognition by DNA molecules for wiring an electric circuit. This study gained considerable resonance and helped pave the way for a new field in nanotechnology using the self-assembly properties of biological molecules to construct miniature engineering systems.
  • His research has focused on the way water orders next to molecules and the effect of this ordering on inter-molecular interactions in biologically relevant solutions. Within this framework, Prof. Sivan’s group designs and builds unique, ultra-high-resolution atomic force microscopes.
  • His research has led to patents and industrial applications. Recently, an Israeli start-up company was established in the field of single cell analysis for cancer diagnostics, based on the technology developed in Prof. Sivan’s lab.
  •  Prof. Sivan is the founding director of the Russell Berrie Nanotechnology Institute (RBNI), which he headed between 2005 and 2010.  RBNI has led the scientific revolution in nanotechnology at Technion and has placed the university at the forefront of global research in the field. RBNI made headlines when Prof. Sivan and Dr. Ohad Zohar engraved the entire Hebrew Bible onto a tiny silicon chip. The Nano Bible was written as part of an educational program developed by the Institute to increase young people’s interest in science and especially in nanotechnology. In 2009, President Shimon Peres presented the Nano Bible to Pope Benedict XVI during his official visit to Israel. Today, there are three copies of the chip worldwide: at the Vatican Library, the Smithsonian Museum in Washington D.C., and the Israel Museum in Jerusalem. The establishment of RBNI spearheaded the development of Israel’s national nanotechnology program, and together with centers established in other Israeli universities, has positioned the country as a world leader in nanotechnology.

APPOINTMENTS

Recently, Prof. Sivan was appointed to head the National Advisory Committee in Quantum Science and Technology of the Council for Higher Education’s Planning and Budgeting Committee (PBC). The committee outlined the national quantum academic program, which was adopted and launched last year.

Prof. Sivan has served as a member of the Israeli National Committee for Research and Development (MOLMOP) and the Scientific Advisory Committee of the Batsheva de Rothschild Foundation. He currently serves on the Advisory Committee of the Maof Fellowships Committee for advancing Arab faculty and is a member of the Israeli Wolfson Foundation Advisory Board.

AWARDS

Prof. Sivan is a renowned lecturer in Israel and abroad. He was awarded with numerous prizes including

  • the Mifal Hapais Landau Prize for the Sciences and Research,
  • the Rothschild Foundation Bruno Prize,
  • the Israel Academy of Sciences Bergmann Prize,
  • the Technion’s Hershel Rich Innovation Award, and
  • the Taub Award for Excellence in Research.

Palmaz, Pinchuk, Schatz, Simpson and Yock are the 10th recipients of the Russ Prize for innovations leading to the widespread adoption of PCI at NAE Gala Ceremony, 2/20/2019, WashDC

 

Reporter: Aviva Lev-Ari, PhD, RN

 

National Academy of Engineering, Ohio University Award 2019 Russ Prize

Five interventional cardiologists awarded biennial $500,000 prize for innovations leading to the widespread adoption of PCI

National Academy of Engineering, Ohio University Award 2019 Russ Prize

January 3, 2019 — Ohio University and the National Academy of Engineering announced the 2019 Fritz J. and Dolores H. Russ Prize will be given to Julio Palmaz, Leonard Pinchuk, John Simpson, Richard Schatz and Paul Yock for innovations leading to the widespread adoption of percutaneous coronary intervention (PCI), also known as angioplasty with stent or coronary angioplasty. The $500,000 biennial prize, which recognizes a bioengineering achievement that significantly improves the human condition, cites PCI for “seminal contributions to coronary angioplasty, enabling minimally invasive treatment of advanced coronary artery disease.”

“The Russ Prize recipients personify engineering creations that advance health and healthcare every day,” said NAE President C. D. Mote, Jr.  “The PCI makes a remarkable contribution to patient well-being, helping millions afflicted with advanced coronary artery disease and significant angina. “

Ohio University alumnus and esteemed engineer Fritz Russ, BSEE ’42, HON ‘75, and his wife, Dolores Russ, established the biennial prize in 1999 with a multimillion dollar gift to Ohio University. They modeled it after the Nobel Prize, with the goal of recognizing bioengineering achievements worldwide that are in widespread use.

“This innovation — truly, sets of innovations — enables the treatment of coronary artery disease without the complexities, cost and risk of open heart surgery. Most of us have a friend or relative who has benefited greatly from angioplasty treatment,” said Russ College Dean Dennis Irwin. “These contributions have truly improved the human condition. Rewarding such innovations was the Russes’ intent.”

Percutaneous coronary intervention, also referred to as percutaneous transluminal coronary angioplasty (PTCA), is a minimally invasive procedure that uses a catheter to place a small structure called a stent to open up blood vessels in the heart that have been narrowed by plaque buildup. PCI improves blood flow, thus decreasing heart-related chest pain, making patients feel better and increasing their ability to be active. Ten of millions of patients have benefited from PCI worldwide, and this procedure has replaced or significantly delayed the need for open heart coronary bypass surgery.

Julio C. Palmaz, inventor of the first U.S. Food and Drug Administration (FDA)-approved balloon-expandable vascular stent (1990), is Ashbel Smith Professor at the University of Texas Health Science Center in San Antonio and scientific adviser of Vactronix Scientific. The Palmaz stent is on display at the Smithsonian’s National Museum of American History in Washington, D.C. In 1994 he and Richard Schatz created a modified coronary stent — two Palmaz stents joined by a single connector — approved by the FDA as the first stent indicated for the treatment of failure of coronary balloon angioplasty. The Palmaz-Schatz stent became the gold standard for every subsequent stent submitted for FDA approval.

Leonard Pinchuk is an inventor and entrepreneur in biomedical engineering, with 128 U.S. patents and 90 publications. He has co-founded 10 companies where his major accomplishments include invention of the Nylon 12 angioplasty balloon, helical wire stent, modular stent-graft, a drug-eluting stent (Taxus), several biomaterials (Bionate and polystyrene-block-isobutylene-block-styrene [SIBS]), a novel glaucoma tube (InnFocus MicroShunt), and the next-generation intraocular lens. He is a Distinguished Research Professor of Biomedical Engineering at the University of Miami.

John Simpson has helped revolutionize the field of cardiology through innovations that fundamentally altered how physicians treat cardiovascular disease. In 1981 he created a new catheter system for coronary angioplasty with an independently steerable guidewire in the central lumen of the balloon catheter, patented as the over-the-wire balloon angioplasty catheter. He now focuses his efforts on the treatment of vascular disease through the development of new technologies combined with a new approach to optical imaging.

Richard Schatz is research director of cardiovascular interventions at the Scripps Heart, Lung and Vascular Center, and director of gene and stem cell therapy. He is a recognized international expert in interventional cardiology and has published and lectured extensively. His seminal work in coronary stents spurred a revolution in the treatment of coronary artery disease — over 2 million of them are placed annually worldwide, with an immeasurable impact on relieving mortality and morbidity, improving patients’ lives, and reducing healthcare costs.

Paul Yock is the Martha Meier Weiland Professor of Medicine and founding co-chair of Stanford’s Department of Bioengineering, with courtesy appointments in the Graduate School of Business and the Department of Mechanical Engineering. He is also founder and director of the Stanford Byers Center for Biodesign. He has authored over 300 peer-reviewed publications, chapters, and editorials and two textbooks, and holds over 50 U.S. patents. Yock is internationally known for his work in inventing, developing and testing new devices, including the Rapid Exchange stenting and balloon angioplasty system, which is now the primary system in use worldwide. He also invented the fundamental approach to intravascular ultrasound imaging and founded Cardiovascular Imaging Systems (CVIS), later acquired by Boston Scientific.

“Ohio University is honored to join the National Academy of Engineering in recognizing these accomplished individuals, who have contributed to a bioengineering advancement that has enabled better health for heart patients across the world,” said Ohio University President M. Duane Nellis. “Their multi-disciplinary collaboration that lead to the development of PCI, a technology that has revolutionized coronary health, truly embraces the vision that Fritz and Dolores Russ had when creating the Russ Prize.”

Palmaz, Pinchuk, Schatz, Simpson and Yock are the 10th recipients of the Russ Prize. They will receive the award at a National Academy of Engineering gala ceremony in Washington, D.C., on Feb. 20, 2019

Reporter: Aviva Lev-Ari, PhD, RN

Personal memories from attending the Decision Theory Colloquium @Stanford University, 1985 – 1988

The Colloquium was led by Prof. Kenneth Arrow, Economics, Prof. Amos Tversky, Psychology and Prof. Abernethy, Healthcare System expert at Graduate School of Business.

These years, I worked at SRI, International in Menlo Park, CA. The Monthly meetings were on WEDs at 4PM.

I learned a lot and was most privileged to be inspired by the Colloquium leaders, students, postdocs and to attend Prof. Kenneth Arrow Class on An Economics Approach to Information Theory in Fall 1988.

Arrow Lectures

The Arrow Lecture Series on Ethics and Leadership honors the late Nobel Laureate Kenneth Arrow, the Joan Kenney Professor of Economics and Professor of Operations Research, Emeritus.

Professor Arrow made many contributions to welfare economics, social choice theory and collective decision-making. He was also a founding member of the Ethics in Society Undergraduate Honors program. Ken passed away in 2017.

Kenneth Arrow, one of the greatest economists of the twentieth century, died last month at the age of ninety-five. He was of the generation of economists whose ideas were formed by the dislocation and turmoil of the Great Depression and World War II, a generation that includes John Nash, Paul Samuelson, Harold Hotelling, and Milton Friedman. Now when so much of economics is straightjacketed by a failure to take account of ethical considerations, Arrow’s work demonstrates that economics is fundamentally a moral science. Whether tackling climate change, international security, healthcare provision, inequality, or racial prejudice, for Ken, economics was first and foremost a means to help improve human well-being. Indeed, his focus on well-being led him to consider the importance of trust and moral codes, as well as government regulations, for market behavior. Homo economicus cannot be out for himself alone. Read more of Debra Satz’s tribute to Ken.

In 2005, Patrick Byrne endowed the Arrow Lecture Series in Ethics and Leadership. Byrne is the founder and CEO of Internet retailer Overstock.com and he holds a Ph.D. in philosophy from Stanford.

Mourning the Loss of NIAMS Director Stephen Katz, M.D., Ph.D. – A Leader in Immunology of Skin Diseases

Mourning the Loss of NIAMS Director Stephen Katz, M.D., Ph.D. – A Leader in Immunology of Skin Diseases

Dr. Stephen Katz.Stephen Katz, M.D., Ph.D., Director, National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS)NIH

It is with a profoundly heavy heart that I share with you the sad news that we have lost one of our most beloved leaders at NIH. Steve Katz, M.D., Ph.D., the long-time Director of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), died early this morning after suffering a catastrophic stroke. Just yesterday he was working on a presentation for this morning’s Steering Committee, and now he is gone. I am still reeling from this sudden, tragic turn of events. But I want to reflect on who Steve was and what he meant to NIH, the biomedical research enterprise, and to me personally, as a close friend.

Steve was born in New York, grew up in Bethesda, trained in internal medicine and dermatology, and came to NIH in 1974 as a Senior Investigator in the Dermatology Branch at the National Cancer Institute, initiating a highly productive research program in the immunology of skin diseases. Six years later he was Branch Chief. And when a Director for NIAMS was sought in 1995, it was Steve who emerged as the ideal candidate. Over these years he has ably led an Institute that has made major contributions to research across a broad portfolio of disorders that affect millions of Americans. As just one example, it has been my personal privilege to work closely with him on the Accelerated Medicines Partnership (AMP) project that is shedding dramatic new light on the pathogenesis of rheumatoid arthritis and lupus. Steve was also a remarkable nurturer of his staff, always striving to give them the credit for progress.

But I would claim that there is no Institute Director who has done more over the last two decades to help the entire NIH enterprise flourish. When Harold Varmus, Elias Zerhouni, Raynard Kington, Larry Tabak, or I needed someone to wrestle a difficult budget issue to the ground, we called Steve. When we needed someone to provide wise advice on a complex topic (most recently, Big Data), we called Steve. When we wanted someone to mentor to new member of NIH leadership, we called Steve. And he always said yes. His legacy is simply profound.

I am also fortunate to claim Steve as a friend. It was a gift to be in his orbit of wisdom, warmth, and humor. It was a joy to see how he immediately fell in love with a grandchild just a month ago. He was also a fellow musician, and he taught me a song that is now a favorite. There is a verse of this song (B’Shana Ha’ba’a) for which the words now seem particularly appropriate. Here they are in English, though Steve also taught me the Hebrew version:

Men have dreams, men have died
To make a bright tomorrow,
And their vision remains in our hearts.
Now the torch must be passed
With hope and not in sorrow,
And a promise to make a new start.

The torch has been passed. May we strive to live up to the example of dedication and wisdom set by our dear friend Steve, even as we convey our deep condolences to his wife Linda and his children.

With sorrow for our shared loss, but gratitude for Steve’s many gifts to us,

Francis S. Collins, M.D., Ph.D.
Director

Angelika Amon wins 2019 Breakthrough Prize in Life Sciences

Four other MIT researchers to receive New Horizons Prizes in math and physics; two alumni win Breakthrough Prize in Fundamental Physics.

Angelika Amon, an MIT professor of biology, is one of five scientists who will receive a 2019 Breakthrough Prize in Life Sciences, given for transformative advances toward understanding living systems and extending human life.

Amon, the Kathleen and Curtis Marble Professor in Cancer Research and a member of MIT’s Koch Institute for Integrative Cancer Research, was honored for her work in determining the consequences of aneuploidy, an abnormal chromosome number that results from mis-segregation of chromosomes during cell division.

The award, announced this morning, comes with a $3 million prize.

“Angelika Amon is an outstanding choice to receive the Breakthrough Prize,” says Tyler Jacks, director of the Koch Institute and the David H. Koch Professor of Biology. “Her work on understanding how cells control the decisions to divide and the effects of imbalances in chromosome number has helped shape how we think about normal development and disease. Angelika is a fearless investigator and a true scientist’s scientist. All of us in the Koch Institute and across MIT are thrilled by this news.”

Two MIT alumni, Charles Kane PhD ’89 and Eugene Mele PhD ’78, both professors at the University of Pennsylvania, will share a Breakthrough Prize in Fundamental Physics. Kane and Mele are being recognized for their new ideas about topology and symmetry in physics, leading to the prediction of a new class of materials that conduct electricity only on their surface.

BREAKTHROUGH PRIZE PANEL DISCUSSIONS

(5:30 – 7:00PM PST)

Is there (intelligent) life in the Universe?

Featuring Jocelyn Bell, Astronomy, 2018 Laureate; John Hardy, Neuroscience, 2017 Laureate; and Kim Nasmyth, Molecular Biology, 2018 Laureate

Astronomers have been looking for life beyond Earth for decades, but have so far found nothing. But the recent discovery that almost all stars probably host planets may have changed the game. How likely are we to find primitive life? How hard is it to get from cells to brains? And why have we not seen evidence of civilizations?

What are the limits of science?

Featuring Andrei Linde, Theoretical Physics, Cosmology – 2012 Laureate; Gary Ruvkun, Molecular Biology, Genetics, 2015 Laureate; and  Xiaowei Zhuang, Biophysics, 2019 Laureate

 

Science has shown us a universe more and more distant from our familiar world: at microscopic and cosmic scales, at the dawn of time and remote stages of evolutionary history. But is this process limitless? What are the furthest and smallest physical and biological objects we can see? Can we ever know what happened at the moment of the Big Bang? And how far back can we retrace the origin of life on Earth?

Is time travel possible?

Nima Arkani-Hamed, Theoretical Physics, 2012 Laureate; Daniel Harlow, Theoretical Physics,  2019 Laureate; Daniel Jafferis, Theoretical Physics,  2019 Laureate; and Aron Wall, Theoretical Physics, 2019 Laureate

 

Time travel is a staple of science fiction, but how does mainstream science see it? Is it forbidden by the laws of physics? And if not, could it ever be a practical possibility? And do scientists even agree about what time is?
