Marion Pepper is an assistant professor for the department of immunology at the University of Washington.

From kindergarten through high school, Marion Pepper attended an all-girls school outside Philadelphia that placed a lot of emphasis on the sciences. “The major benefit was that I never knew there were ‘things girls couldn’t do,’” she said. “I think it was really empowering.”

While in high school, though, Pepper found two passions – writing and biology, and she could never quite decide which to pursue. So, she did both and graduated from a small college in Massachusetts with her bachelor’s in both English and biology. Coming out of college, Pepper thought she wanted to follow in her grandfather’s footsteps and become a medical doctor, so she started taking pre-med classes. But, when her high school biology teacher got sick and her high school needed a substitute, Pepper stepped up and ended up loving it. She taught at the school for four more years. “Then I got bored with teaching all the science and instead wanted to do the science and test out my own hypotheses,” she said, adding that she also “kept thinking more and more about doing science and less and less about treating people.”

Pepper’s identical twin had already graduated with her doctorate in developmental genetics, and Pepper started down the same path. While taking an immunology class, though, she fell in love with it, switching gears again. “It sort of found me, more than I found it,” she said. “I tried on a lot of different hats and this was the one that fit the best.” She had always been intrigued by developmental biology – how cells change and function and what regulates that. For her, though, immunology and specifically infectious disease research, was that “but on speed.” “These cells have to develop fast, but also have to do it in competition with something that wanted to kill them,” she said, explaining her focus in the study of the immune system, or immunology. “It is a puzzle to figure out how cells win against things that are invading.” The Seattle area is prime with immunologists and researchers looking for immunotherapies to treat and cure cancer. Pepper, though, is studying infectious diseases such as malaria and allergens looking to both make better vaccines and suppress allergic responses. Coming to Seattle was a great move for her, she said because it is a great place to be for immunology. “Our department is down in South Lake Union and I love it because we have Seattle BioMed across the street, Fred Hutch down the street, Juno is moving in next door,” she said. “The Institute for Systems Biology and Benaroya Research Institute and all these other places are within a 10-block radius from our department, which really facilitates collaboration.”

Zika has arrived in the Northwest. Will it spread? The short answer: “It’s pretty unlikely, at this point,” says Justin Roby, an immunologist at the University of Washington who specializes in flaviviruses (a genus of viruses that includes dengue, West Nile and Zika).

Zika Has Arrived in the Northwest. Will it Spread?

Article By Samantha Larson, Crosscut

Doctors confirmed the eighth case of Zika in King County this week, bringing the total number of infections found in Washington State up to 24. Zika puts fetuses at risk of microcephaly, a condition that affect’s a baby’s head size, and thus brain development.

In all of these instances, the virus was acquired while traveling in Latin America or the Caribbean. But Zika is now spreading in Miami — the first cases of local transmission within the continental U.S. Does that mean that mosquitoes could spread the disease here in Seattle, too?

The short answer: “It’s pretty unlikely, at this point,” says Justin Roby, an immunologist at the University of Washington who specializes in flaviviruses (a genus of viruses that includes dengue, West Nile and Zika).

But don’t breathe a sigh of relief just yet.

None of the more than 40 mosquito species found in Washington are effective carriers of this particular virus. Zika is most commonly transmitted by a species of mosquitoes called Aedis aegypti and, a bit less commonly, by another species called Aedes albopictus. Simply put, the weather here is too cold for those types of mosquitoes, which prefer the tropics. (In fact, for a variety of reasons, we have relatively few skeeters here at all.)

While the range of Zika-carrying mosquitoes, particularly albopictus, does include large portions of the U.S., from Delaware to California, and is increasing as climate change continues to cause temperatures to rise, at present, Washington is a safe distance from any of the bugs’ potential habitat.

“There may be rare instances where the mosquito is imported accidentally,” Roby explains — on a shipment of fruits or vegetables, for example. “But I don’t imagine they’ll be able to establish themselves here because of the winters we have.”

Congratulations to Dr. Chrissie Lim for successfully defending her dissertation on Thursday, August 4, 2016.  Her dissertation title is “Alternative splicing takes control of cytokine signaling.”  Dr. Lim spent her time in the University of Washington Immunology graduate program under the mentorship of Dr. Ram Savan and working in his lab at UW Medicine's South Lake Union Campus.

A class of white cells that has long been thought to play a relatively minor role in the body’s defenses against malaria infection may, in fact, be a potent weapon against the malaria parasite. These cells may be key to developing more effective vaccines, according to a report today in the journal Immunity. UW Medicine and Seattle Children’s researchers headed the study. The findings suggest that these white blood cells, called IgM memory B cells, may be more important in the body’s early response to malaria re-infection than another group of cells, called IgG memory B cells, that for years have been the focus of malaria-vaccine research, said Marion Pepper, University of Washington assistant professor of immunology. She led the research project. “The focus on IgG memory B cells in malaria vaccine development may be why malaria vaccines developed to date have not proven very effective,” Pepper said. Read the full UW Health Sciences News Beat Article.

Seattle Times consults with Immunology Assistant Professor Dr. Marion Pepper on allergic reactions. 

Marion Pepper, an assistant professor in the University of Washington’s immunology department, said people have allergic reactions because their bodies’ adaptive immune systems have developed a memory that causes them to rapidly build up a defense.

That’s good when an infectious disease is trying to invade, but not when it’s a harmless allergen.

“That memory response leads to this massive activation of cells, and that leads to symptoms of allergic asthma, skin allergies or pollen allergies,” Pepper said. “We all get exposed to these allergens. It’s not really understood why some people have a higher propensity to respond than others.” Genetics and environment are believed to contribute, she said. And the misery comes en masse: “Generally, if you’re allergic to one thing … you’re actually allergic to multiple things,” Pepper said.

Vice President Joe Biden, Dr. Phil Greenberg, and Dr. Stanley Riddell

Biden started his visit with a tour of the lab of Fred Hutch researcher Dr. Stanley Riddell, accompanied by Dr. Phil Greenberg. Both Greenberg and Riddell are leaders in the field of immunotherapy. Last month, Riddell made headlines when he presented preliminary findings at the American Association for the Advancement of Science’s annual meeting of a clinical trial showing complete remissions in many patients with acute lymphoblastic leukemia. The trial participants were treated with a form of immunotherapy called adoptive T-cell therapy, which uses intact, living T cells — isolated from the patient’s blood and reprogrammed specifically to target the disease — to eliminate tumors. Some patients, for whom no other treatments had worked and who were only weeks from death, are still alive 18 months later, Riddell said.

"We've really worked at understanding the cells that we are engineering in a different way from any other center .... It's allowed us to treat patients with extremely small doses of cells," he said.

When asked by Biden why that matters, Riddell explained: "It's relevant because it makes the process of generating a cell product faster and more cheaply," ultimately making it more affordable and accessible for patients. 

Every time Riddell sees patients in the clinic, he goes back to his research with a new sense of urgency, he said. “The courage of patients is inspiring, and it makes me realize that we don’t have the best [treatments] yet. We have to do better.”

This year alone, 600,000 people in the U.S. will die of cancer, noted Gilliland in his welcoming remarks to Biden. “At Fred Hutch, our goal is to cure cancer, not just treat it.”

Congratulations to Dr. Travis Friesen for successfully defending his dissertation on Monday, February 8, 2016.  His dissertation title is“Tolerance induction in recent thymic emigrants.”  Dr. Friesen spent his time in the University of Washington Immunology graduate program under the mentorship of Dr. Pam Fink and working in the Fink Lab at South Lake Union.

“It caused us to change our priorities,” said Gale, Professor of Immunology and director of the UW Center for Innate Immunity and Immune Disease.

Samples of Zika virus from the outbreak raging across Brazil and Latin America arrived at the University of Washington last month, where they were quickly locked in a biosafety freezer, awaiting research aimed at stopping the germ tied to growing numbers of devastating birth defects. The surge of the mosquito-borne virus has lent new urgency to early tests of a small, druglike molecule that one day may thwart not only that virus, but also the next threat that explodes across the globe, said Michael Gale Jr., the UW immunologist leading the work.
