Can mitochondrial transfer between cells help reduce inflammation in autoimmune diseases?
Mitochondria are the power plants of cells, but they also send signals that control inflammation. Recent research shows that mitochondria can move from one cell to another. This transfer helps reshape the immune environment and can turn down the volume on harmful immune attacks in autoimmune diseases.
What the research says
Studies show that mitochondria move between cells through tunnels, tiny bubbles, and direct connections. This movement changes how immune cells use energy and how they behave. By shifting the balance of energy use, transferred mitochondria can stop immune cells from becoming too aggressive 3.
In autoimmune hepatitis, a specific type of liver disease, researchers found that mitochondria moved from stem cells to overactive immune cells. This transfer helped the immune cells stop producing harmful chemicals and reduced liver damage significantly 4. The process also changed how these cells made energy, moving them away from a state that drives inflammation 4.
Another study focused on a type of immune cell called CD4 T cells, which often drive autoimmune attacks. When mitochondria were transferred from stem cells to these T cells, the cells stopped making the inflammatory proteins that cause tissue damage. The transferred mitochondria also lowered the expression of a specific protein called T-bet, which tells these cells to attack 6.
However, the release of mitochondrial parts into the blood can sometimes trigger inflammation instead of calming it. This means the process is complex and depends on the specific signals and conditions present in the body 5.
What to ask your doctor
- Could mitochondrial transfer therapies be appropriate for my specific autoimmune condition?
- What are the current clinical trials investigating mitochondrial transfer for immune regulation?
- How might my current medications or health status affect the safety of mitochondrial-based treatments?
- What are the potential side effects of therapies that rely on cell-to-cell mitochondrial exchange?
