Getting a flu shot every year can be a pain. One UW Medicine researcher is hoping to make the yearly poke a thing of the past with the development of a universal vaccine that would protect from all strains of influenza virus, even as the viruses genetically shape-shift from year to year.

Nitrogen-fixing bacteria are the chief means by which nitrogen gas in the air is changed into a form that plants and animals can use. Roughly 10 percent of these nitrogen-fixing microorganisms contain the genetic code for manufacturing a back-up enzyme, called iron iron-only nitrogenase, to do their job.

Recent research reveals that this enzyme allows these microorganisms to convert nitrogen gas to ammonia and carbon dioxide into methane at the same time. The ammonia is the main product; the methane is only a sideline.

This enzymatic pathway is a previously unknown route for the natural biological production of methane.

The findings are reported Jan. 15 in Nature Microbiology. The senior author is Caroline Harwood, the Gerald and Lyn Grinstein Endowed Professor of Microbiology at the University of Washington School of Medicine. The lead author is Yanning Zheng, a postdoctoral student in her lab.

Affiliate Associate Professor of Microbiology Jesse D. Bloom, Ph.D., of the Fred Hutchinson Cancer Research Center has been named a Howard Hughes Medical Institute (HHMI) Investigator for 2018, joining a select group of top scientists nationally. Read more here.

Jesse Bloom is fascinated by evolution.

Think how amazing it is, he says, that in nature, small, random genetic changes can add up to something new and wonderful – a stark contrast to the world of things. “If you make random mutations to your car with a baseball bat, you’re probably not going to improve the car very much,” he says. “So what is it about biology that allows living things to be so good at evolving?”

Bloom is tackling this question by helping to pioneer new approaches for studying evolution. He’s combining biology with computational wizardry. “Traditionally, evolutionary biology has been an observational science,” he explains. Researchers looked back on the creation of new species, like Darwin’s finches, or bold new innovations, like the ability to fly, then searched for the genetic steps that paved the way.

But thanks in part to Bloom, scientists don’t have to wait for nature to do its work. “Now we can do large-scale experiments in the lab that can help to explain evolution,” Bloom says. In his own lab, he’s making tens of thousands of mutations in flu viruses to see what effect they have. At the same time, he’s also charting genetic changes that appear in nature. Bloom’s goal is to discern patterns in evolution and use his mathematical modeling skills to predict what’s coming – offering a major public health advance.

His work is paying off. In one recent discovery, Bloom and his collaborators uncovered how the flu virus managed to develop resistance to the drug Tamiflu. One key mutation prevents the drug from attacking flu viruses. But that genetic change, by itself, is actually lethal to the virus because it causes the virus to break apart, Bloom discovered. Several other genetic alterations shore up the virus, letting it survive the drug-blocking mutation.

Another mystery has been the sequence of genetic steps that flu viruses take as they evolve from year to year. Bloom tackled this question by analyzing genetic changes in viruses in immunocompromised patients, whose flu infections often last for months. Not only do these viruses mutate rapidly, he found, but the changes surprisingly parallel what happens to viruses out in the world.

The similarity suggests that, with clever mathematical sleuthing, scientists can get better at guessing what new strains humanity will face in coming years. “I don’t think we will ever be able to completely forecast the future, but it will be interesting to see how good we can get,” says Bloom.

He is uniquely suited to the task. Growing up in Hamilton, Montana, Bloom loved all types of science, including biology, physics, chemistry, math, and computer programming. The problem was picking just one. Fortunately, at the time, biologists were beginning to explore the power of computers, so Bloom was able to combine his quantitative bent with his fascination for evolution.

After studying protein folding as a University of Chicago undergraduate, Bloom wanted to do something more mathematical, such as using his modeling expertise to predict proteins’ shapes from their sequence. That turned out to be fiendishly difficult, “so I thought maybe I can study how they evolved,” he says. That led him to the California Institute of Technology as a PhD student and postdoc, working to harness evolution to engineer new and useful enzymes. There, “I learned I was more of a curiosity-driven biologist than a problem-solving engineer,” he says.

Now, that curiosity – backed up by rigorous computation – may finally bring answers to some of the great questions of evolution.

NEW YORK – May 30, 2018 – The Blavatnik National Awards for Young Scientists today announced the 31 U.S. National Finalists who will compete for the world’s largest unrestricted prizes for early career scientists. Each year, three Blavatnik National Laureates in the categories of Life Sciences, Chemistry, and Physical Sciences & Engineering are awarded $250,000 each.

The Blavatnik National Finalists were selected from 286 outstanding faculty-rank researchers nominated by 146 institutions across 42 states (see list with brief summaries below).

2018 Blavatnik National Finalists in Life Sciences

The 2018 National Finalists in Life Sciences have addressed complex questions that reflect the next chapter in human health and development. The Finalists have expanded our understanding of the ways in which the human microbiome governs microbial infection and human health by studying the interactions between bacteria, pathogens and their host. They have developed extraordinary new technologies and discoveries, from harnessing cutting-edge CRISPR gene-editing technology to improve crop yields, editing RNA-based disease targets, identifying key metabolic and physical cues that control the growth and internal organization of cells, developing unique computational approaches to study cancer progression, and inventing technologies that advance our understanding of the brain and organ tissue development.

Janelle Ayres (Salk Institute for Biological Studies) – Working at the intersection of immunology and microbiology, Dr. Ayres’ pioneering research on host-pathogen interactions is re-defining our understanding of health. Dr. Ayres’ discovery that microbes have evolved mechanisms to promote the health of the host to support their own survival reveals a beneficial role for microbes in maintenance of host health. Promoting host “tolerance” of microbes may offer a novel therapeutic approach to treating infections that is not reliant on antibiotics.

Edward Boyden (Massachusetts Institute of Technology) – Dr. Boyden has invented multiple groundbreaking technologies that have advanced our understanding of the brain. Dr. Boyden revolutionized neuroscience research with the co-invention of optogenetics—using light to control cells in genetically modified living tissues. More recently, he developed expansion microscopy, a creative approach that involves physically expanding a specimen using swellable polymers to achieve high-resolution images instead of increasing the resolution of the microscope.

Clifford Brangwynne (Princeton University) – Dr. Brangwynne’s pioneering work at the interface of cell biology and soft matter physics focuses on membrane-less organelles within cells, and how their physical state plays a role in associated biological functions. Dr. Brangwynne’s seminal discovery that membrane-less organelles behave as liquids rather than solids has introduced a major paradigm shift in our understanding of intracellular organization and sheds light on the material physics underlying organelle processes.

Zachary Lippman (Cold Spring Harbor Laboratory) – Having identified several genes that determine flower production and crop productivity, geneticist Dr. Lippman is applying cutting-edge CRISPR gene-editing technologies to improve crop yield. Dr. Lippman has demonstrated that manipulating the genome of plants to fix undesirable combinations of mutations introduced by breeding or to introduce new gene mutations that improve the health or flowering capacity of the plant can improve yield. In doing so, Dr. Lippman’s work has the potential to help address one of our top public health concerns: global food supply shortage.

Franziska Michor (Dana-Farber Cancer Institute) – Dr. Michor’s work has led to the first clinical trials based on the evolutionary mathematical modeling of cancer. Dr. Michor investigates the evolutionary dynamics of cancer using mathematical modeling methodologies and a unique combination of approaches.

Benjamin Tu (UT Southwestern Medical Center) – Molecular and cellular biologist Dr. Tu studies metabolism and cellular processes using both yeast and mammalian systems. He has uncovered novel molecular mechanisms that govern cell growth and proliferation in response to metabolic and nutritional cues. Dr. Tu’s research focuses on the metabolic state of cells and responses to conditions that induce or halt cell proliferation to promote survival and homeostasis.

Gene Yeo (University of California, San Diego) – Dr. Yeo has created multiple novel technologies that have increased our understanding of RNA processing and RNA-binding proteins. Dr. Yeo was the first to target RNA (as opposed to DNA) using the CRISPR/Cas9 system in live cells and demonstrated reversal of key pathological features of microsatellite expansion diseases by destroying toxic RNA in patient cells. Dr. Yeo’s discoveries hint at the enormous possibilities of tapping the therapeutic potential of RNA manipulation in the treatment of human disease.

For instance, his research investigating hot Jupiter-class exoplanet atmospheres has provided strong evidence for the existence of two unique classes of exoplanetary atmospheres on these planets and is shaping our understanding of planetary composition and formation.

Ryan Hayward (University of Massachusetts Amherst) – As a polymer scientist and chemical engineer, Dr. Hayward creates material systems with elastic buckling instabilities that transform their shape, surface morphology and material properties, on demand. He has developed microscale polymeric sheets that self-fold into origami structures and 3D shapes in response to external stimuli such as light and heat. His work also focuses on the assembly of nanoscale materials such as polymer nanowires and polymer-embedded nanoparticles to control macroscale properties.

Sergei V. Kalinin (Oak Ridge National Laboratory) – A materials scientist and nanoscientist, Dr. Kalinin creates novel technologies to study and control the functionality of nanomaterials by combining imaging, big data and materials theory. Dr. Kalinin and his collaborators recently challenged a 25-year paradigm by proposing and implementing the atomic forge — a new approach that uses the atomically-focused beam of a scanning transmission electron microscope to control and direct matter, manipulating single atoms to enable fundamental physical studies and also to develop quantum computing and single spin magnetoelectronic devices.

Jure Leskovec (Stanford University) – Dr. Leskovec is a computer scientist who has revolutionized our understanding of large social and information networks. Using experiments, analysis and modeling, he was first to validate the “six degrees of separation” hypothesis and demonstrated how influence and trust propagate through social networks and shape online communities, viral networking and media bias.

Ying Shirley Meng (University of California, San Diego) – Dr. Meng, a materials scientist and engineer, utilizes computational approaches and unique operando and in-situexperimental approaches to understand, develop and optimize the behavior and operation of electrolyte and electrode materials in batteries to drive better energy storage and conversion performance. She and her team recently developed a novel type of liquefied gas electrolyte material that allows battery operation at ultra-cold temperatures.

Brian Metzger (Columbia University) – As a theoretical astrophysicist, Dr. Metzger works on a broad range of topics related to the “transient” universe.

The lack of new antibiotics is among the most critical challenges facing medicine. Researchers have been on the hunt for new drugs to combat "superbugs" that cannot be penetrated by current antibiotics.

This side-view x-ray shows a pseudomonas infection at the top of the lung. It appers as a torn shroud with black cavities. 

Rather than looking for drugs that forcibly penetrate bacteria, researchers tried a new approach: tricking bacteria into taking up a molecule that looks like food, but wreaks havoc once inside. A study of this approach shows initial success in mice and humans.

The work is described in the Sept. 26, 2018, issue of Science Translational Medicine. The two primary investigators, Pradeep Singh and Christopher Goss, are faculty members at the University of Washington School of Medicine.

Their study focused on one superbug, Pseudomonas aeruginosa, which causes infection in the lungs, urinary tract, wounds and elsewhere. It is a particular problem in patients whose ability to fight infection is impaired because of illnesses such as cystic fibrosis, cancer and AIDS.

The researchers studied gallium because it is a metal similar to iron, a critical nutrient for bacteria during infection.

"The body goes to great lengths to keep iron away from bacteria, and infecting organisms crank up special systems to import iron and steal it from the host," said Singh, the senior author and a UW professor of microbiology and medicine.

Goss, a UW professor of medicine and pediatrics and the paper's first author, described gallium as a Trojan horse. "Gallium not only fails to nourish bacteria as iron would, it actually harms them."

The researchers also discovered how gallium works. "Gallium disrupts machinery that bacteria use to make new DNA, and without this the bacteria can't multiply," said co-author Bradley Britigan, professor of internal medicine at the University of Nebraska Medical Center. "This and other essential processes require iron, and gallium is a monkey wrench that shuts the system down."

In lab studies, bacteria developed resistance to gallium at low rates, and gallium's potency was increased when used in combination with some existing antibiotics. These factors led the researchers to test gallium in mice and then in humans.

In mice, researchers found that a single dose cured lethal lung infections. They then studied gallium in 20 people with cystic fibrosis (CF) and difficult-to-treat lung infections caused by antibiotic-resistant Pseudomonas bacteria.

"Our preliminary study in a small group of people with CF suggests that gallium is safe and improves patients' lung function," Goss said. "These are exciting results, but we need to do more studies to determine if gallium can be developed into a routine, safe treatment."

The idea of disrupting bacterial nutrition as an antimicrobial strategy was raised in the 1800s by Louis Pasteur, but such treatments have been difficult to develop.

Could gallium-based therapies be the exception to that experience? "That's our hope, and we're encouraged by these results, but we've have to be cautious and do more work before we'll know," said Singh.

Researchers at the UW School of Pharmacy, Johns Hopkins University, University of Chicago, University of Iowa, and Osaka City University in Japan also contributed to this study.

The research was supported by the National Institutes of Health (UM1HL119073, R01HL085868, P30DK089507, and K24HL102246), Cystic Fibrosis Foundation, Arcadia Foundation, Burroughs Wellcome Fund, the U.S. Department of Veterans Affairs, and the University of Washington's Institute for Translational Health Sciences.

Can you provide a brief overview of your lab’s current research focus?

The research in the Greenberg laboratory focuses on the emerging field of sociomicrobiology – the group-behaviors of microbes. We are interested in the biochemistry and molecular biology of environmental sensing/response with a particular emphasis on a form of chemical communication between bacteria termed “quorum sensing”. In quorum sensing, bacteria synthesize chemical signals as cues to coordinate activities of individuals in groups. This signaling plays a critical role in the development of many bacterial infections.

 What is the significance of the findings in this publication?

In many plant-associated bacteria, the quorum sensing receptor no longer senses its own quorum sensing signals – instead the system has evolved to recognize compounds present in the plant host. Although these plant-responsive receptors were described more than a decade ago, the factor(s) they sense were unknown until now. Our work describes the identification of an ethanolamine-derived molecule that serves as signal for a plant-responsive receptor in a Poplar tree endophyte, Pseudomonas sp GM79. Ethanolamine is a building block for plant membrane phospholipids and signaling molecules. This discovery connects at least one of the plant-responsive receptors to a growing understanding of ethanolamine chemistry and responses of bacterial cells to ethanolamine and its derivatives. These plant-responsive systems regulate virulence and symbiosis in plant-associated bacteria, so defining how they work and the plant molecules that control them could contribute to improved crop disease management and the resourceful use of biofertilizers.

 What are the next steps for this research?

Our discovery leads to several questions regarding the biology and biochemistry of this interkingdom signaling system: do similar receptors in other plant-associated bacteria respond to the same, or related, ethanolamine-derived signal? What impact does the signal have on plant host-bacteria interactions? These are just some of the questions we are interested in answering in the near future.

With many disease-causing bacteria ratcheting up their shields against current drugs, new tactics are vital to protect people from treatment-resistant infections.

Lowering mutation rates in harmful bacteria might be an as yet untried way to hinder the emergence of antimicrobial-resistant pathogens. This proposed strategy comes from recent findings in infectious disease research at UW Medicine in Seattle.

Dear Colleagues:

With great sadness, I write to inform you of the sudden passing of Dr. James Champoux, professor and former chair of the UW School of Medicine Department of Microbiology. He died on Monday [May 13, 2019], a week after being diagnosed with pancreatic cancer, at the age of 76.

Dr. Champoux was appointed department chair in October 2007, after serving twice before as interim chair, and he continued in that role until earlier this year. He was dedicated to his colleagues, truly generous in his service to the School of Medicine, and justifiably proud to lead one of the premier biological science departments in the country.

The Department of Microbiology has a national reputation for high-quality teaching and an international reputation for excellence in research. In the most recent U.S. News & World Report rankings, the department is No. 2 in the nation for best graduate programs in microbiology and No. 4 in the world among global universities.

A Seattle native, Dr. Champoux was part of the first group of students admitted to the University of Washington Honors Program when it was founded in 1961. After graduating with a major in chemistry, he completed his doctorate degree in biochemistry at Stanford University in 1970.

Dr. Champoux’s early career coincided with the biology revolution that began in the 1970s — a time when rapid advances in microbiology and the development of biotechnology were starting to increase our understanding of all living systems. He made his first contribution to this revolution during a postdoctoral fellowship at the Salk Institute in San Diego when he discovered an enzyme called DNA topoisomerase I while working with Nobel Prize recipient Renato Dulbecco.

When Dr. Champoux returned home to join the UW Department of Microbiology faculty in 1972, he embarked on an illustrious academic career that continued for the next 47 years. During this time, he made major contributions to our understanding of oncogenesis and viral infections through his research on enzymes and retroviruses.

Dr. Champoux published more than 125 papers, and he was recognized with numerous honors, including a Guggenheim Fellowship (1980-81) and the prestigious NIH Merit Award (1998). He was elected by his peers to be a fellow of the American Academy of Microbiology (2005) and a member of the Washington State Academy of Sciences (2010). More recently, he was named a fellow of the American Association for the Advancement of Science (2017).

As department chair, Dr. Champoux recruited six new faculty members and worked to increase diversity among our faculty and graduate students. He was committed to excellence in education and exemplified this important faculty role as a wonderful teacher of undergraduate and graduate students. In 1985, he won the UW Distinguished Teaching Award.

The news of Dr. Champoux’s unexpected passing has been received by all of his colleagues with shock and sadness. On their behalf, I want to extend our deepest sympathies to his wife, Sharon, and daughter, Katie, on their profound loss. We are very fortunate that Dr. Champoux chose to spend his faculty career in the Department of Microbiology. He will be greatly missed.

Salmonella enterica serovar Typhi causes typhoid fever only in humans. Murine infection with S. Typhimurium is used as a typhoid model, but its relevance to human typhoid is limited. Non-obese diabetic-scid IL2rγnull mice engrafted with human hematopoietic stem cells (hu-SRC-SCID) are susceptible to lethal S. Typhi infection. In this study, we use a high-density S. Typhi transposon library in hu-SRC-SCID mice to identify virulence loci using transposon-directed insertion site sequencing (TraDIS). Vi capsule, lipopolysaccharide (LPS), and aromatic amino acid biosynthesis were essential for virulence, along with the siderophore salmochelin. However, in contrast to the murine S. Typhimurium model, neither the PhoPQ two-component system nor the SPI-2 pathogenicity island was required for lethal S. Typhi infection, nor was the CdtB typhoid toxin. These observations highlight major differences in the pathogenesis of typhoid and non-typhoidal Salmonellainfections and demonstrate the utility of humanized mice for understanding the pathogenesis of a human-specific pathogen.

Dr Rudy Urbano, a recent graduate of our program, has just been awarded a prestigious Hanna Gray Fellowship from the Howard Hughes Medical Institute. Dr Urbano was a member of Dr Ferric Fang's Lab and defended in Autumn 2017.
