Scientists may have discovered a surprising new way to help the immune system fight blood cancer using a vitamin that many people already consume every day.
Researchers from the University of Minnesota found that vitamin B3 may strengthen special immune cells called natural killer cells, helping them attack cancer more effectively.
The discovery could become especially important for patients with leukemia and lymphoma whose cancers no longer respond well to standard treatments.
Cancer treatment has improved greatly over the past few decades. Doctors now use chemotherapy, radiation, targeted medicines, and advanced immune therapies to treat many different cancers.
Even so, many blood cancers remain difficult to cure completely. Some cancers return after treatment, while others become resistant to medicine over time.
Scientists have therefore been exploring new ways to help the body’s own immune system destroy cancer cells more successfully.
Natural killer cells are one of the immune system’s most important defense tools. These cells constantly move through the body searching for dangerous cells, including infected cells and cancer cells.
Once they detect a threat, they launch attacks designed to destroy it.
For many years, researchers hoped natural killer cells could become a major form of cancer therapy. However, the cells often become weak inside cancer patients. They may lose energy, wear out quickly, or fail to attack cancer cells strongly enough.
The Minnesota research team wanted to solve this problem.
Instead of heavily modifying the cells using complex genetic engineering, they used vitamin B3, also called nicotinamide, to improve the cells naturally.
Vitamin B3 is an essential nutrient that helps the body produce energy and maintain healthy cells. It has long been recognized as important for human health and is found in many everyday foods.
When researchers treated natural killer cells with vitamin B3 in the laboratory, they noticed major improvements. The cells became more active, survived longer, and attacked cancer cells more aggressively.
The vitamin-treated cells also appeared less likely to become exhausted during the fight against cancer.
Scientists then tested the treatment in 30 patients with difficult blood cancers.
The results surprised many researchers. Among 19 lymphoma patients, 11 achieved complete recovery after treatment using the strengthened natural killer cells. Another three patients showed partial improvement.
Researchers reported that many patients improved within just a few weeks.
The findings suggest that vitamin B3 may significantly improve the effectiveness of immune-cell therapies.
Vitamin B3 already has an important place in medical history. In the 1930s, scientists discovered that people lacking this vitamin developed pellagra, a dangerous disease causing skin damage, digestive problems, weakness, and mental symptoms.
Adding vitamin B3 to foods eventually helped eliminate pellagra in many parts of the world.
Now researchers believe the same vitamin may support a completely different medical purpose by helping immune cells survive and function more effectively.
Scientists say the research remains in the early stages and larger studies will still be necessary.
Future clinical trials will help determine whether the treatment works consistently in larger groups of patients and whether it can help treat additional forms of cancer.
Researchers are also studying exactly why vitamin B3 improves natural killer cell performance and how long the benefits may last inside the body.
The work is part of the growing field of cancer immunotherapy, which focuses on helping the immune system fight disease naturally.
Many scientists believe immunotherapy may become one of the most important cancer treatment strategies in the future because it can sometimes target cancer cells more precisely than traditional treatments.
The findings also highlight the connection between nutrition and immune health. Scientists are increasingly learning that nutrients and metabolism can strongly affect how immune cells behave.
