Characteristics and mechanisms of T-cell senescence: A potential target for cancer immunotherapy.
Abstract
Immunosenescence, the aging of the immune system, leads to functional deficiencies, particularly in T cells, which undergo significant changes. While numerous studies have investigated age-related T-cell phenotypes in healthy aging, senescent T cells have also been observed in younger populations during pathological conditions like cancer. This review summarizes the recent advancements in age-associated alterations and markers of T cells, mechanisms, and the relationship between senescent T cells and the tumor microenvironment. We also discuss potential strategies for targeting senescent T cells to prevent age-related diseases and enhance tumor immunotherapy efficacy.

Research summary
The paper discusses T-cell senescence and its implications for cancer immunotherapy, which relates to the aging immune system. While it addresses mechanisms and potential strategies to target senescent T cells, it primarily focuses on cancer treatment rather than directly addressing the root causes of aging or lifespan extension. Thus, it contributes solid research but has limited impact on the broader field of longevity research.
