Researchers Find Potential Neurodevelopmental Outcomes Linked to Brain Tissue Differences in Newborns Exposed to HIV
Researchers at Children’s Hospital of Philadelphia (CHOP) in collaboration with the Botswana Harvard Health Partnership identified measurable differences in brain tissue patterns between newborns exposed to HIV during pregnancy but not infected and those with no HIV exposure.

Breakthrough Discovery Reveals How Connection Between Mitochondrial Vulnerability and Neurovasculature Function Impacts Neuropsychiatric Disease
Researchers found that mitochondrial dysfunction in the blood-brain barrier (BBB) may lead to neuropsychiatric disease in some patients with 22qDS. The researchers also demonstrated that a class of FDA-approved cholesterol drugs could potentially be repurposed to treat this dysfunction.
Children’s Hospital of Philadelphia Researchers Find Promising Preclinical Data for Expanding Use of Drug for Primary Mitochondrial Diseases
Researchers found that a new drug therapy currently in clinical trials for a form of primary mitochondrial disease – Mitochondrial Encephalomyopathy, Lactic Acidosis, and Stroke-like episodes (MELAS) syndrome – was safe and effective in multiple preclinical zebrafish models.

Children’s Hospital of Philadelphia Researchers Find that Missing Messenger RNA Fragments Could be Key to New Immunotherapy for Hard-to-Treat Tumors
A new study, led by researchers CHOP, identified tiny pieces of messenger RNA that are missing in pediatric high-grade glioma tumors but not in normal brain tissues. Preclinical research indicates that these missing RNA fragments can make difficult-to-treat tumors more responsive to immunotherapy. The findings were recently published in the journal Cell Reports.
Breathing new life into CPR
Pediatric cardiac arrests affect over 15,000 children in the United States each year. Less than half of these children will survive, and among those who do, neurologic injury is all too common. The typical cause for a child to need CPR: a problem with the child's breathing or lungs.
