Balancing mTOR for healthy ageing

Oct 3, 2023

The mTOR signaling pathway is crucial for cell growth and metabolism, affecting aging and disease. Properly regulating mTOR could treat age-related conditions and potentially extend lifespan, but careful modulation is essential to prevent negative side effects.

Key takeaways


  • mTOR pathway and longevity: The mTOR pathway’s role in cell growth and metabolism suggests that its careful regulation is key to slowing down the ageing process and promoting increased lifespan
  • Pharmacological targeting of mTOR: Drugs like rapamycin that target the mTOR pathway show promise in extending the period of life free from age-related diseases, indicating a potential pharmacological route to enhance longevity
  • Risks of overactive mTOR signaling: Excessive activity of the mTOR pathway is associated with accelerated cellular ageing and a higher incidence of age-related diseases, emphasising the need for precise control of this pathway
  • Importance of mTOR balance: While mTOR inhibition has benefits, it’s crucial to maintain a balance since the pathway also supports essential cellular functions. Over-inhibition could disrupt these processes and lead to negative health outcomes
