据中证报报道，以色列内盖夫本-古里安大学近日发布公报说，该校研究人员发现了一类可能有助于延 缓衰老的免疫细胞，为诊疗衰老引起的相关疾病提供新思路。人体内的衰老细胞是指在压力作用下因染 色体受损而不可逆地停止分裂的细胞。随着年龄增长，衰老细胞会在机体组织内累积，可导致许多与年 龄相关的疾病。 *免责声明：文章内容仅供参考，不构成投资建议 *风险提示：股市有风险，入市需谨慎 公司方面，据中证报表示，A股相关概念股有阳普医疗 、阳光诺和等。 公报说，一类此前未被充分认识的CD4辅助性T细胞亚群会随年龄积累。研究发现，CD4辅助性T细胞具 有"清理"衰老细胞的能力。研究团队认为，这一发现还可为延缓衰老以及诊断和治疗衰老引起的相关疾 病提供新方向。 ...

Core Insights - Researchers at Ben-Gurion University of the Negev have discovered a type of immune cell that may help delay aging and provide new approaches for diagnosing and treating age-related diseases [1][2] Group 1: Research Findings - Aging cells in the human body are defined as cells that irreversibly stop dividing due to chromosomal damage under stress, accumulating with age and leading to various age-related diseases [1] - A previously underappreciated subset of CD4 helper T cells accumulates with age, which was initially overlooked by researchers [1] - A study in Japan on centenarians revealed that their immune systems are rich in this subset of helper T cells [1] Group 2: Mechanism and Implications - CD4 helper T cells have the ability to "clean up" aging cells, as confirmed by experiments on mice [1] - Reducing the number of these helper T cells in mice leads to accelerated aging and shorter lifespan, while increasing their numbers helps delay aging [1] - The research suggests that rather than needing an "overactive immune system," a properly functioning immune system aligned with life stages is essential for combating aging [1]
