CHOP Researchers Improve Fitness of Cells Used in Cell Transplants
CHOP researchers find exposing cells to a small molecule drug improves cell fitness during hematopoietic stem cell transplants, which could improve ex vivo gene therapy.
College Athletes Experience Worse Post-Injury Outcomes for Concussions Suffered Outside of Sports
Female athletes also had more severe symptoms associated with these injuries.
CHOP Researchers Develop Novel Method Using MRI to Study Diseases Modeled in Zebrafish
This initial study found evidence linking changes in organ development with symptoms seen in certain human mitochondrial diseases.
CHOP Researchers Lead International Expert Panel, Curating Evidence for Over 100 Genes Causing Leigh Syndrome Spectrum
Forty researchers met regularly over four years to determine which genes have the strongest link to the most common pediatric form of mitochondrial disease.
Multidisciplinary Task Force Develops Clinical Recommendations for Rare, Life-Threatening Hyperinflammatory Syndromes
Hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome (MAS) are overlapping hyperinflammatory syndromes that involve disorganization and malfunction of the immune system, leading to widespread inflammation and organ damage. The conditions can progress rapidly, making early identification and management key for preventing organ failure and death.
CHOP Researchers Show Epilepsy and Autism Symptoms in Dravet Syndrome May Be Caused by Separate Mechanisms
Dravet syndrome is a severe neurodevelopmental disorder defined by treatment-resistant epilepsy and features related to autism spectrum disorder.

FDA Approves First Gene Therapy for Duchenne Muscular Dystrophy
For decades, doctors and researchers have been working diligently to discover new treatments and provide more options for patients with Duchenne muscular dystrophy (DMD), a debilitating genetic disease that ravages the muscles in the body and leads to a loss of movement and coordination.
CHOP and Penn Researchers Show Gene Editing Tools Can be Delivered to Perinatal Brain
CHOP researchers have identified an ionizable LNP that can deliver mRNA base editing tools to the brain to mitigate CNS disease in perinatal mouse models.

CHOP Researchers Develop Versatile and Low-Cost Technology for Targeted Long-read RNA Sequencing
CHOP researchers have developed a versatile and low-cost technology for targeted sequencing of full-length RNA molecules.
Researchers Find COVID-19 Causes Mitochondrial Dysfunction in Heart and Other Organs
While mitochondrial function recovered in the lungs, function did not recover in the heart and other organs, leading to long-term damage and a possible explanation for detrimental effects of “long COVID”.
