Zeaxanthin Found to Enhance Cancer Immunotherapy
Researchers at the University of Chicago have discovered that zeaxanthin, a plant-based compound known for supporting eye health, can enhance the immune system's ability to fight cancer. The study, published in Cell Reports Medicine, found that zeaxanthin boosts the activity of CD8+ T cells, which are crucial for identifying and destroying cancer cells. By stabilizing the T-cell receptor complex, zeaxanthin improves T-cell activation and cytokine production, leading to stronger anti-tumor responses. In mouse studies, zeaxanthin slowed tumor growth and enhanced the effectiveness of immune checkpoint inhibitors, a type of cancer immunotherapy.
