What Is mTOR Signaling? The Science Behind Cellular Growth

mTOR signaling is a cellular pathway that helps regulate growth, energy use, protein synthesis, and nutrient sensing within the body. In this video, we explain what mTOR signaling is, how it works, and why it matters in the context of aging, metabolism, healthspan, and healthy aging. Full article: https://longevityinsights.co.uk/what-is-mtor-signaling/ In longevity science, mTOR signaling is widely studied because it plays a central role in how cells respond to nutrients, stress, and growth signals. Researchers examine mTOR in relation to metabolism, autophagy, inflammation, and biomarkers of biological aging to better understand how this pathway may influence cellular maintenance, resilience, and long-term health outcomes. Understanding mTOR signaling can help clarify why it is considered one of the key pathways involved in aging and longevity research.
