Researchers at UCLA found that creatine can help the immune system fight cancer more effectively. They discovered that creatine boosts the activity of dendritic cells, which detect tumors and activate killer T cells. This could make immunotherapy work for more people.

Creatine is a popular supplement used by athletes to improve strength and performance. But new research from UCLA suggests it may have another surprising role: helping the immune system fight cancer. The study found that creatine boosts the activity of dendritic cells, which are specialized immune cells that detect tumors and activate killer T cells.

The researchers tested this by examining the activity of metabolic genes in dendritic cells that had entered tumors in mice. They discovered that the gene responsible for producing the creatine transporter was much more active in tumor-infiltrating dendritic cells than in healthy tissue. This means that these cells were able to take up creatine and use it to boost their energy levels.

The team then engineered dendritic cells that lacked the creatine transporter. Without the ability to take up creatine, these cells survived less effectively, became less active, and were far less capable of preparing T cells to recognize and attack tumors.

Why It Matters

This research is important because it could lead to new ways to treat cancer using immunotherapy. Currently, only about 20-40% of patients experience meaningful benefits from this treatment. If creatine can help boost the immune system's ability to fight cancer, it could make immunotherapy more effective for more people.

Key Facts

• Researchers at UCLA found that creatine boosts the activity of dendritic cells, which are specialized immune cells that detect tumors and activate killer T cells.
• The study used experiments in mice and human cells to test the effects of creatine on dendritic cells.
• Creatine increased intracellular ATP levels in dendritic cells, which is essential for their activation.
• The researchers compared creatine's role to that of a rechargeable battery, allowing dendritic cells to store and release energy as needed.
• The study suggests that adding creatine during the production of dendritic cell cancer vaccines could improve their effectiveness.
