Abstract
Torpor is a naturally occurring state of metabolic suppression that enables animals to adapt and survive extreme environmental conditions. Inspired by this adaptation, researchers have pursued synthetic torpor—an artificially induced, reversible hypometabolic state with transformative medical potential. Achieving synthetic torpor has been pursued for over a hundred years, with earlier work focused on identifying drugs for systemically suppressing metabolism. Breakthroughs in 2020 identified key torpor-regulating neurons in mice, opening new opportunities for neuromodulation-based metabolic control. Synthetic torpor has been applied in animal models for various medical applications, including ischaemic protection, organ preservation, radiation protection and lifespan extension. This Perspective examines the fundamental concepts of natural torpor, advances in approaches to induce synthetic torpor and medical applications of synthetic torpor. The capability of synthetic torpor to suppress whole-body metabolism has the potential to transform medicine by offering novel strategies for medical interventions.
期刊介绍：
Nature Metabolism is a peer-reviewed scientific journal that covers a broad range of topics in metabolism research. It aims to advance the understanding of metabolic and homeostatic processes at a cellular and physiological level. The journal publishes research from various fields, including fundamental cell biology, basic biomedical and translational research, and integrative physiology. It focuses on how cellular metabolism affects cellular function, the physiology and homeostasis of organs and tissues, and the regulation of organismal energy homeostasis. It also investigates the molecular pathophysiology of metabolic diseases such as diabetes and obesity, as well as their treatment. Nature Metabolism follows the standards of other Nature-branded journals, with a dedicated team of professional editors, rigorous peer-review process, high standards of copy-editing and production, swift publication, and editorial independence. The journal has a high impact factor, has a certain influence in the international area, and is deeply concerned and cited by the majority of scholars.
