Researchers Develop Genetic Blueprint to Combat T Cell Exhaustion in Cancer Therapy
A multi-institutional study led by researchers from the UNC Lineberger Comprehensive Cancer Center, the Salk Institute for Biological Studies, and UC San Diego has identified new genetic mechanisms that influence the state of CD8+ killer T cells. These cells are crucial for immune defense, targeting virus-infected and cancer cells. However, they can become ineffective in chronic infections or tumors, entering a state known as T cell exhaustion. The study, published in Nature, outlines a detailed atlas of CD8+ T cell states, revealing how these cells transition from protective to dysfunctional states. By manipulating specific genetic switches, researchers found they could restore the tumor-killing function of T cells without compromising their long-term immune memory. This discovery has significant implications for improving immunotherapy and infectious disease research.
