Creatine, a common supplement long used to enhance athletic performance, may play a role in cancer treatment by boosting the body’s immune response. Research from the University of California in Los Angeles (UCLA) indicates that creatine powers dendritic cells, which are responsible for directing killer T-cells to identify and attack tumor cells, according to findings published in the journal iScience.
How Creatine Affects Immune Cell Function
Scientists at UCLA have identified that creatine acts as a “rechargeable battery” for dendritic cells, providing the energy necessary to navigate the nutrient-poor environment of a tumor. While previous studies focused on how the supplement fuels killer T-cells, this research shows a broader impact on the immune system’s infrastructure.
According to Lili Yang, a professor of microbiology, immunology and molecular genetics at UCLA and the study’s senior author, creatine energizes the entire support network for T-cells. This holistic enhancement could theoretically improve the efficacy of existing immunotherapies, which currently only work for a subset of patients.
Dendritic cells capture fragments of tumors and direct killer T-cells to attack.
Evidence from Mouse Models
In the study published in iScience, researchers administered daily injections of creatine to mouse models with melanoma. The results showed a measurable slowing of tumor growth. Furthermore, the treated dendritic cells released higher levels of chemical signals, which effectively recruited additional immune cells into the tumor site.
James Elsten-Brown, a graduate student in Prof. Yang’s lab and co-first author of the study, noted that the findings suggest two potential clinical applications. Creatine could be used as an adjunct to enhance the immune response in patients already receiving immunotherapy, or as a tool to improve the quality of dendritic cell-based vaccines before they are administered to patients.
Current Limitations and Medical Advice
While these findings are promising, researchers emphasize that the data is limited to cell and mouse models. There are currently no clinical recommendations for human patients regarding the use of creatine as a cancer treatment.
The supplement has been widely used for decades and is generally considered safe. However, the study authors warn that individuals currently undergoing cancer treatment must consult their physicians before introducing any new supplements into their regimen.
Frequently Asked Questions
Can creatine cure cancer?
No. The current research only suggests that creatine may enhance the immune system’s ability to fight cancer cells in laboratory models. It is not a standalone treatment for cancer.
Is it safe to take creatine during cancer treatment?
Patients should not add creatine to their regimen without consulting their doctor. While the supplement is considered safe for general use, its effects on specific medical treatments and individual patient health must be evaluated by a professional.
How does creatine help the immune system?
According to the UCLA research, creatine provides energy to dendritic cells, allowing them to remain active and effective even when they are competing with fast-growing tumor cells for limited nutrients.
