Background Atherosclerosis (AS) is a chronic inflammatory disorder with substantial global prevalence, wherein macrophage polarization and vascular smooth muscle cells (VSMCs) phenotypic switching are critical pathogenic events. Although G protein-coupled receptor 132 (GPR132) is markedly expressed in macrophages, its specific role and mechanism in AS-associated macrophage polarization remain incompletely understood. Methods P...

Background Lung-resident (rEos) and inflammatory (iEos) eosinophil subtypes were initially characterized in mouse models of asthma and have been proposed to contribute differentially to inflammation and remodeling in human allergic asthma (AA). While microRNAs (miRNAs) and their transfer through exosomes may play important regulatory roles in immune signaling in asthma, miRNA profiles specific to eosinophil subtypes remain unc...
