New Discovery Paves Way for Next-Generation Malaria Vaccine

Drs. Debashree Goswami (front) and Nana Minkah are working with their Kappe Lab colleagues to develop a vaccine for malaria. New research published by Goswami and her teammates paves the way for a novel, next generation vaccine against Plasmodium falciparum, the parasite that causes the deadliest form of malaria in humans.

In an unprecedented first, scientists at Seattle Children’s Research Institute have developed a genetically attenuated parasite (GAP) that arrests late in the liver stage of human malaria. Their findings published in JCI Insight pave the way for a novel, next-generation GAP vaccine against Plasmodium falciparum, the parasite that causes the deadliest form of malaria in humans.

According to Dr. Debashree Goswami, a fellow in the Kappe Lab at the research institute’s Center for Global Infectious Disease Research and lead author of the paper, a vaccine candidate based on their findings has the potential to offer protection to those living in regions where the transmission of malaria is widespread throughout the population.

Engineered T Cells for Type 1 Diabetes Move Closer to Clinic

Dr. Jane Buckner of the Benaroya Research Institute at Virginia Mason and Dr. David Rawlings of Seattle Children’s Research Institute are leading gene editing research to develop new therapies for autoimmune conditions like type 1 diabetes.

For much of the last decade, Dr. David Rawlings, director of Seattle Children’s Research Institute’s Center for Immunity and Immunotherapies, has dreamed of developing a therapy for children with type 1 diabetes that doesn’t involve insulin injections but uses a person’s own immune cells to target and treat the disease.

Now, new research and a fresh infusion of funding bring this dream closer to reality, and nearer to opening a first-in-human clinical trial of an experimental therapy at Seattle Children’s in collaboration with research partner Benaroya Research Institute at Virginia Mason (BRI).

“What started as a dream is now within reach,” Rawlings said. “My hope is that our research will lead to a new treatment that turns off the destructive immune response leading to development of type 1 diabetes in children.” Read full post »

Are Children Making Antibodies That Will Protect Against Future COVID-19 Infections?

More than 50 research studies to understand, detect, treat and prevent the novel coronavirus in children and families have launched at Seattle Children’s since the virus emerged in late 2019. The following post is part of the “Quest(ion) for Discovery” series highlighting this research in progress and the search for answers that could result in major scientific breakthroughs that save lives and slow the spread of the virus.

When Dr. Janet Englund, a member of the Center for Clinical Translational Research at Seattle Children’s Research Institute, received news in late February that a Seattle Children’s patient had tested positive for the novel coronavirus and represented the first example of community transmission in Washington state, she knew things as we knew them were never going to be the same.

Englund, who has long studied respiratory viruses and their transmission in children and frequently provides her expertise as part of national scientific advisory panels, believed we were facing something very different from any pandemic Seattle – or the world for that matter – had ever seen before.

She and her collaborators quickly proposed supplements to their existing studies primarily focused on seasonal influenza, so they could begin to learn about how the new coronavirus impacts children. One study, which she discusses in greater detail here, asks: Are children making antibodies that will protect against future COVID-19 infections? Read full post »

How Might COVID-19 Reshape this Generation of Children?

More than 50 research studies to understand, detect, treat and prevent the novel coronavirus in children and families have launched at Seattle Children’s since the virus emerged in late 2019. The following post is part of the “Quest(ion) for Discovery” series highlighting this research in progress and the search for answers that could result in major scientific breakthroughs that save lives and slow the spread of the virus.

An expert in screen time for children, Dr. Dimitri A. Christakis, leads a team of researchers out of Seattle Children’s Research Institute’s Center for Child Health, Behavior and Development. In a recently published editorial in JAMA Pediatrics, Christakis argues that it’s critical to focus on overlooked decisions, such as the return to school, in the wake of the COVID-19 surge because of its lasting implications for children.

Here, he shares research his team has proposed to understand some of the effects of COVID-19 on child development and wellness while addressing the question: How might COVID-19 reshape this generation of children? Read full post »

Should Schools Go Screen-Free: Study Reveals Significant Portion of U.S. Middle and High Schools Do Not Limit Phone Use During Lunch or Recess

The latest screen-time related research from Dr. Pooja Tandon, a child health and development expert at Seattle Children’s Research Institute, was inspired by her oldest son.

“When my son entered middle school, I learned that students in many middle and high schools were allowed to have their phones with them at all times,” Tandon said. “I looked into this a bit more and found that even in schools where policies limited use during class, cell phones could still be used unrestricted during lunch and recess.”

This struck Tandon, an associate professor of pediatrics at the University of Washington School of Medicine, whose research focuses on promoting healthy active and outdoor play for children and teens.

“My fellow pediatricians and I follow guidelines that recommend children and teens enjoy two hours of age-appropriate recreational screen time a day,” she said. “Yet, many children may be spending most of their waking hours in school with what could be unsupervised and unrestricted access to their phones.” Read full post »

Do Llama Nanobodies Hold the Secret to Fighting COVID-19 in Humans?

More than 50 research studies to understand, detect, treat and prevent the coronavirus in children and families have launched at Seattle Children’s since the virus emerged in late 2019. The following post is part of the “Quest(ion) for Discovery” series highlighting this research in progress and the search for answers that could result in major scientific breakthroughs that save lives and slow the spread of the virus.

At Seattle Children’s Research Institute, Dr. John Aitchison co-leads the Center for Global Infectious Disease Research, the largest pediatric infectious disease research group in the U.S.

Aitchison’s lab and a team of scientists from Rockefeller University are researching how nanobodies produced by a llama’s immune system can be used to develop a therapy that eliminates COVID-19 in humans. Here he answers the question: Do llama nanobodies hold the secret to fighting COVID-19 in humans? Read full post »

Can a Greater Understanding of COVID-19 in Children Reduce the Overall Impact of the Coronavirus?

When health officials learned a Seattle Children’s patient tested positive for the novel coronavirus 2019 (COVID-19) in late February, it sent a ripple through health and scientific communities nationwide. It was the first example of community transmission in the state of Washington, indicating the virus causing COVID-19 had likely been spreading in Seattle and the surrounding region undetected.

It was a moment Seattle Children’s had prepared to face since establishing an incident command center more than one month prior. From this command center, teams from across the organization met to support advance planning and coordinate actions for a potential COVID-19 surge in the region.

“Before there were any confirmed cases in the U.S., Seattle Children’s anticipated the potential for an outbreak in our region,” said Dr. Jeff Sperring, Seattle Children’s Chief Executive Officer. “Over the past several weeks, we have provided specialized training for our team, established strict protocols for health and hygiene, and consolidated essential supplies so that we would be ready to protect our patients.”

Now other cities are turning to Seattle for insight on what to expect as the growing pandemic reaches their communities. On the Pulse offers a behind the scenes look at how the leading pediatric hospital and research institute at the epicenter of the country’s COVID-19 outbreak is responding to this quickly evolving global health issue.

Childhood Tics: Will My Child Outgrow Them or is It Something More?

Childhood tics come in all shapes and sizes. Tics can range from a subtle nasal sniff or throat clearing to a more severe head snap or vocal outburst.

Tics that start in elementary school and continue during adolescence are also common. According to Dr. Dararat Mingbunjerdsuk, a neurologist that specializes in movement disorders at Seattle Children’s Neurosciences Center, up to 10-20% of school-age children may exhibit a tic at one point in their life.

“Tics that come and go are the most common cause of movement disorder we see in the clinic,” she said. “The vast majority of children eventually outgrow their tics or the tics become less frequent or less severe as the person enters adulthood.”
