Zeaxanthin Boosts Cancer Immunotherapy Efficacy

Why it matters: Zeaxanthin could improve the efficacy of existing cancer immunotherapies for patients, potentially leading to stronger anti-tumor responses.
- Zeaxanthin, a common eye-health nutrient, was found to have a new function in boosting anti-tumor immunity, according to the University of Chicago Medical Center.
- Scientists discovered that zeaxanthin strengthens CD8+ T cells by stabilizing the T-cell receptor complex, leading to increased activation and improved ability to kill tumors.
- Mouse studies showed that adding zeaxanthin to the diet slowed tumor growth, with even more pronounced effects when combined with immune checkpoint inhibitors.
- Laboratory experiments demonstrated that zeaxanthin enhanced human T cells' ability to destroy melanoma, multiple myeloma, and glioblastoma cells.
A common eye-health nutrient, zeaxanthin, found in everyday vegetables, has been discovered to significantly enhance the body's anti-cancer immunity by strengthening T cells and boosting the effectiveness of immunotherapy treatments. Researchers at the University of Chicago Medical Center found that this safe and accessible compound could supercharge the fight against various cancers, with human trials identified as the crucial next step.
