Oxidative-stress-induced telomere instability drives T cell dysfunction in cancer

Key Points

• To investigate how oxidative stress affects telomere stability and T cell function in cancer.
• Analyzed telomere length in T cells exposed to oxidative stress
• Assessed T cell functionality through cytokine production tests
• Utilized cell culture models to simulate cancer environments
• Oxidative stress significantly shortened telomeres in T cells
• Increased telomere instability correlated with reduced T cell functionality
• Altered cytokine production indicated impaired immune response in cancer context
