Measles virus is perhaps the most contagious virus in the world, affecting 10 million children worldwide each year and accounting for 120,000 deaths. An article published in the Nov. 2, 2011 issue of Nature explains why this virus spreads so rapidly.
The discovery by Roberto Cattaneo, Ph.D., at Mayo Clinic in Rochester, MN, in collaboration with Veronika von Messling, DVM, at the Centre INRS–Institut Armand-Frappier and research teams at several other universities opens up promising new avenues in cancer treatment.
Measles virus spreads from host to host primarily by respiratory secretions. This mode of transmission explains why the virus spreads so quickly and how it resists worldwide vaccination programs to eradicate it.
The study in Nature shows for the first time how the measles virus "exits" its host via nectin-4, which is found in the trachea. While viruses generally use cellular receptors to trigger and spread infection in the body, measles virus uses one host protein to enter the host and another protein expressed at a strategic site to get out.
Nectin-4 is a biomarker for certain types of cancer, such as breast, ovarian, and lung cancers. Clinical trials are currently under way using a modified measles virus. Because measles virus actively targets nectin-4, measles-based cancer therapy may be more successful in patients whose cancers express nectin-4. Such therapy could be less toxic than chemotherapy or radiation.
Research was conducted in Dr. Cattaneo's laboratory in collaboration with the Paul Ehrlich Institute in Langen, Germany, the University of Iowa in Iowa City, U.S.A., Centre INRS–Institut Armand-Frappier in Laval, Canada, Inserm UMR 891/CRCM/Institut Paoli-Calmettes/Université d'Aix-Marseille in Marseille, France, and Duke-NUS Graduate Medical School in Singapore.
Institut national de recherche scientifique (INRS) is a graduate and postgraduate research and training university. One of Canada's leading research universities in terms of grants per professor, INRS brings together some 150 professors and close to 700 students and postdoctoral fellows in its centres in Montreal, Quebec City, Laval, and Varennes. INRS research teams conduct fundamental research essential to the advancement of science in Quebec as well as internationally and play a critical role in developing concrete solutions to problems facing our society.

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating....
Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
