未配对的配体是分泌的信号,通过 GP130 样无圆顶受体发挥作用,激活果蝇中的 JAK-STAT 信号传导。与许多哺乳动物细胞因子一样,未配对的细胞因子可以被感染和其他应激激活,并可以促进靶组织中的胰岛素抵抗。然而,这种效应在非炎症生理学中的重要性尚不清楚。在这里,我们确定了健康成年果蝇肌肉中对未配对的 JAK 信号作为代谢调节剂的需求。在没有任何免疫挑战的情况下,成人肌肉显示出基础 JAK-STAT 信号传导活性。巨噬细胞是大部分这种滋补信号的来源。成人肌肉上圆顶感受器的丧失会显着缩短寿命并导致局部和全身代谢病理。这些病理是由于 AKT 过度激活和随之而来的代谢失调造成的。因此,我们确定了从巨噬细胞到肌肉的控制 AKT 活性和代谢稳态的细胞因子信号。
Unpairedligands are secreted signals that act via a GP130-like receptor,domeless, to activate JAK-STAT signaling inDrosophila. Like many mammalian cytokines,unpairedscan be activated by infection and other stresses and can promote insulin resistance in target tissues. However, the importance of this effect in non-inflammatory physiology is unknown. Here, we identify a requirement forunpaired-JAK signaling as a metabolic regulator in healthy adultDrosophilamuscle. Adult muscles show basal JAK-STAT signaling activity in the absence of any immune challenge. Macrophages are the source of much of this tonic signal. Loss of thedomereceptor on adult muscles significantly reduces lifespan and causes local and systemic metabolic pathology. These pathologies result from hyperactivation of AKT and consequent deregulation of metabolism. Thus, we identify a cytokine signal from macrophages to muscle that controls AKT activity and metabolic homeostasis.
