Chronic low-grade inflammation has a key role in the aging process, a state called inflammaging. It is known that the chronic inflammatory condition generates counteracting immunosuppressive state in many diseases. Inflammaging is also associated with an immune deficiency; generally termed as immunosenescence, although it is not known whether it represents the senescence of immune cells or the active remodeling of immune system. Evidence has accumulated since the 1970's indicating that immunosenescence might be caused by an increased activity of immunosuppressive cells rather than cellular senescence. Immune cells display remarkable plasticity; many of these cells can express both proinflammatory and immunosuppressive phenotypes in a context-dependent manner. The immunosuppressive network involves the regulatory subtypes of T (Treg) and B (Breg) cells as well as regulatory phenotypes of macrophages (Mreg), dendritic (DCreg), natural killer (NKreg), and type II natural killer T (NKT) cells. The immunosuppressive network also includes monocytic (M-MDSC) and polymorphonuclear (PMN-MDSC) myeloid-derived suppressor cells which are immature myeloid cells induced by inflammatory mediators. This co-operative network is stimulated in chronic inflammatory conditions preventing excessive inflammatory responses but at the same time they exert harmful effects on the immune system and tissue homeostasis. Recent studies have revealed that the aging process is associated with the activation of immunosuppressive network, especially the functions of MDSCs, Tregs, and Mregs are increased. I will briefly review the properties of the regulatory phenotypes of immune cells and examine in detail the evidences for an activation of immunosuppressive network with aging.

Ageing research reviews

随着人类平均预期寿命的增加，老龄化和与年龄有关的疾病对我们社会的影响也在增加。衰老研究现在是数千个实验室的重点，其中包括遗传学、分子和细胞生物学、生物化学和行为领域的领导者。老龄化研究评论 (ARR) 涵盖了该领域的趋势。它旨在填补一个巨大的空白，即对衰老机制和与年龄相关的疾病的新发现进行批判性评论和观点的来源。对控制细胞增殖、分化和存活的机制理解的快速进展正在导致对衰老调控的新认识。从端粒酶到干细胞，再到能量和氧自由基代谢，这是衰老研究多学科领域令人兴奋的新时代。正在确定延长寿命的操作的细胞和分子基础，例如热量限制，并且正在开发预防与年龄有关的疾病的新方法。 ARR 发表的文章选自衰老研究的广泛领域，重点关注衰老过程的细胞和分子机制以及与年龄相关的疾病，如癌症、心血管疾病、糖尿病和神经退行性疾病。本期刊还介绍了基础衰老研究在延长寿命和预防疾病方面的应用。

As the average life expectancy of humans increases, the impact of aging and age-related diseases on our society is also growing. Aging research has now become a focal point for thousands of laboratories, including leaders in genetics, molecular and cellular biology, biochemistry, and behavioral sciences. Ageing Research Reviews aims to fill a significant gap by providing critical reviews and perspectives on new discoveries related to aging mechanisms and age-related diseases. Rapid advancements in understanding the mechanisms that control cell proliferation, differentiation, and survival are leading to new insights into aging regulation. From telomerase to stem cells, and energy and oxidative metabolism, we are entering an exciting new era in the multidisciplinary field of aging research. The cellular and molecular basis for interventions to extend lifespan, such as caloric restriction, is being identified, and new approaches to prevent age-related diseases are being developed. Articles published in Ageing Research Reviews cover a wide range of topics in aging research, focusing on the cellular and molecular mechanisms of the aging process and age-related diseases such as cancer, cardiovascular diseases, diabetes, and neurodegenerative disorders. This journal also discusses the applications of fundamental aging research in extending lifespan and preventing diseases.
