Monocyte–macrophage dynamics as key in disparate lung and peripheral immune responses in severe anti-melanoma differentiation-associated gene 5-positive dermatomyositis-related interstitial lung disease
•Peripheral immune suppression and pulmonary immune hyperactivation characterise the distinct immune landscapes in anti-MDA5+DM with RP-ILD. | |
•Circulating monocytes transition from an immunosuppressive phenotype in the periphery to proinflammatory and profibrotic Mo-AMs in the lungs. | |
•Chemokines produced by Mo-AMs drive monocyte and other immune cell recruitment to the lungs, amplifying pulmonary inflammation. |
