YAP1-Driven Pathogenic Fibro-Adipogenic Progenitors Secrete IL-6 and FGF21 to Mediate Muscle-Bone Crosstalk and Promote Bone Loss.
It is shown that dysregulated endocrine function of skeletal muscle promotes bone loss through YAP1-driven pathogenic FAPs secreting IL-6 and FGF21, identifying FAP-derived IL-6 and FGF21 as key mediators of muscle-bone crosstalk and establishing the YAP-FAP-myokine axis as a therapeutic target for preventing bone loss in sarcopenia and osteoporosis.
