摘要

细胞衰老的特征是细胞周期阻滞、细胞凋亡抵抗、衰老标志物的表达以及衰老相关分泌表型(SASP)的获得。在这篇综述中,我们讨论细胞衰老在肿瘤微环境中的作用。一些衰老的先天免疫细胞不能维持其抗肿瘤功能,甚至可能促进肿瘤的进展。衰老的CD8+和CD4+ T细胞功能失调,与免疫抑制、血管生成和免疫治疗抵抗有关。基质衰老的研究主要集中在SASP上。SASP是一把双刃剑。它在肿瘤早期促进免疫监视,而在肿瘤晚期抑制肿瘤免疫。癌症治疗中针对衰老的策略主要有四种:诱导衰老、抑制促肿瘤SASP、清除衰老细胞和逆转衰老。虽然尚未在临床实践中,但这些方法对未来的癌症治疗有希望。

The Role of Senescence, its Therapeutic Relevance and Clinical Implications in the Tumor Microenvironment.

Cellular senescence is characterized by cell cycle arrest, resistance to apoptosis, the expression of senescence markers, and the acquisition of senescence-associated secretory phenotype (SASP). In this review, we discuss the role of cellular senescence within the tumor microenvironment. Some senescent innate immune cells fail to sustain their antitumor function and may even promote tumor progression. Senescent CD8+ and CD4+ T cells become dysfunctional and are implicated in immunosuppression, angiogenesis, and resistance to immunotherapy. Research on stromal senescence primarily focuses on the SASP. The SASP functions as a double-edged sword. It promotes immune surveillance in the early stages of a tumor while inhibiting tumor immunity in its advanced stages. Strategies to target senescence in cancer therapies include four main approaches: inducing senescence, inhibiting tumor-promoting SASP, clearing senescent cells, and reversing senescence. Although not yet in clinical practice, these approaches hold promise for future cancer treatments.

期刊介绍: Theranostics serves as a pivotal platform for the exchange of clinical and scientific insights within the diagnostic and therapeutic molecular and nanomedicine community, along with allied professions engaged in integrating molecular imaging and therapy. As a multidisciplinary journal, Theranostics showcases innovative research articles spanning fields such as in vitro diagnostics and prognostics, in vivo molecular imaging, molecular therapeutics, image-guided therapy, biosensor technology, nanobiosensors, bioelectronics, system biology, translational medicine, point-of-care applications, and personalized medicine. Encouraging a broad spectrum of biomedical research with potential theranostic applications, the journal rigorously peer-reviews primary research, alongside publishing reviews, news, and commentary that aim to bridge the gap between the laboratory, clinic, and biotechnology industries.
