A High Dimensionality Approach Reveals Immunopathogenic Responses Driving Severe Pediatric Acute Respiratory Distress Syndrome

To address this gap, we adopted a high-dimensional multi-omics approach to better understand immune dysregulation in PARDS, aiming to identify distinct pathogenic pathways. We show that severe PARDS is marked by interferon-driven immune dysregulation, with pulmonary T cells and myeloid cells exhibiting strong interferon responses and suppressed IL-1 pathways, resulting in impaired immune cell function and reduced IL-1α/β levels.
