Abstract

Abstract

En 中文
• Fibroblasts drive macrophage differentiation toward a collagen-clearing phenotype • Fibroblasts secrete IL-6 to induce MR/CD206–mediated collagen uptake by macrophages • MR/CD206 is rate-limiting for collagen degradation by macrophages in in vivo models • Novel depleter strain reveals fibroblast impact on macrophage phenotype in mice
