Integrated Single-Cell and Machine-Learning Analysis Identifies Antigen-Presenting Macrophage-Associated Genes in Pediatric Community-Acquired Pneumonia.
INTRODUCTION Community-Acquired Pneumonia (CAP) is a major global threat with mortality driven by immune dysregulation. The potential role of antigen-presenting macrophages in coordinating immune responses remains poorly defined in CAP. This study aimed to characterize their cellular landscape and intercellular communi...
