Understanding Mitochondria and Their Decline

Lecture on Mitochondria and Mitochondrial Decline

Introduction to Mitochondria

  • Mitochondria are small organelles in cells responsible for energy generation.
  • Typically, cells have around 100 mitochondria that produce ATP by combusting glucose and oxygen.
  • Mitochondrial DNA (16,000 base pairs) is much smaller than nuclear DNA (3 billion base pairs).
  • Mitochondria have bacterial origins and have evolved over a billion years to become part of eukaryotic cells.

Mitochondrial Decline and Aging

  • Mitochondrial decline with age is linked to many diseases.
  • Cells require energy from mitochondria to function correctly; decline leads to insufficient energy.
  • Mitochondrial DNA damage accumulates over time, contributing to aging and disease.
  • Example: Presenter’s family mitochondrial DNA studies show varying damage scores correlating with age.

Causes and Effects of Mitochondrial Decline

  • Mitochondrial decline can be accelerated by lifestyle factors like smoking and chronic diseases.
  • Damage in mitochondrial DNA increases as we age, impacting health and longevity.
  • Mitochondria are maternally inherited and undergo constant replication, leading to potential errors with age.

Mitochondrial Bio-Reactors and Transplants

  • Proposal to use bio-reactors to grow new mitochondria for transplantation.
  • Transplants could potentially prevent or reverse age-related diseases by replenishing healthy mitochondria.
  • Mitochondrial transplantation could be similar to a blood transfusion, leveraging natural mitochondrial transfer processes in the body.

Mechanisms of Mitochondrial Transplantation

  • Use of platelet-derived mitochondria (mitolets) for transplantation.
  • Platelets produce mitolets, which are absorbed by other cells to replenish mitochondria.

Research and Applications

  • Studies show potential in reversing immune system aging through mitochondrial transplants.
  • Animal studies indicate improved health markers with mitolet injections.
  • Ongoing tests aim to apply this technology for various medical conditions, including eye diseases and possibly Alzheimer's.

Conclusion and Future Implications

  • Mitochondrial transplants could be foundational in longevity treatments and broader medical therapies.
  • Aiming to integrate mitochondrial replenishment into regular medical treatments to address energy deficiencies in cells.
  • Future research and applications could transform approaches to aging and chronic disease management.
