Breakthrough Discovery: Misbehaving Mitochondria Linked to Juvenile Dermatomyositis

Research Update: misbehaving Mitochondria Linked to Juvenile Dermatomyositis. Dr. Christian Lood

The generous support of our community has been instrumental in funding groundbreaking research this year, led by Dr. Christian Lood at the University of Washington and Cure JM’s Center of Excellence at Seattle Children’s Hospital.

With a keen focus on understanding the role of mitochondria, the cell’s energy powerhouses, in juvenile dermatomyositis (JDM), Dr. Lood’s team has made a significant discovery. They have identified calcified mitochondria in the muscle tissue of JDM patients with calcinosis – a finding that sheds new light on understanding JDM.

This groundbreaking research opens the door to potential new treatments for JDM

“By targeting misbehaving mitochondria and inflammation, we aim to develop more effective therapies,” says Dr. Lood. “Additionally, we are working to identify unique mitochondrial biomarkers to tailor individual treatment plans for individual patients.”

In the coming year, Dr. Lood will continue to explore:

  • New treatment targets based on mitochondrial function
  • Developing individual treatment plans using mitochondrial biomarkers
  • The long-term impact of misbehaving mitochondria on JDM and how we might prevent disease progression – essentially stopping JDM in its tracks
  • Collaborations with other research institutions

We are excited about the potential of this new research to improve the lives of children. We will continue to keep you informed on this evolving project and others as they develop.

Why I Walk- Sammie Fish

Why I Walk: Steps Toward a Cure with Sammie Fish

Sammie Fish was 14 when juvenile dermatomyositis (JDM, a rare form of juvenile myositis (JM) changed her life in 2017. A doctor’s warning that she might never reach remission, tied to a lifetime of medication, shook her world. But Sammie, now 21, didn’t back down. Today, she’s a college grad, a new teacher in her dream job, and Co-Chair of Cure JM’s Ohio Chapter alongside her mom. She walks for herself, for kids like her, and for a cure. That’s why hundreds of Cure JM families and friends across the nation join Walk Strong, because every step pushes us toward a JM-free future

2025 Family Conference Finding Hope

Erin and Madi’s Story: Finding Hope at the Cure JM Family Conference

In February 2023, Erin Hicks and her daughter Madi faced a life-altering moment. After a visit to the National Institutes of Health in Seattle, Madi, a vibrant 12-year-old soccer player from Kansas City, Missouri, was diagnosed with juvenile dermatomyositis (JDM). “We walked out feeling overwhelmed and lost,” Erin recalls. Research fueled panic as Madi’s condition worsened, her energy fading on the soccer field. Hope was slipping away.
