Experimental Gerontology

Experimental Gerontology (Exp. Gerontol.) is a journal of ageing science published by Elsevier. Founded in 1964 by Alex Comfort, it concentrates on the mechanisms of ageing and on intervention, became fully open access in January 2023, appears as twelve to fourteen volumes a year, and had a 2025 impact factor of 5.1.《实验老年学》（Experimental Gerontology''''，缩写 Exp. Gerontol.''）是爱思唯尔出版的老年科学刊物，1964 年创刊，创办人为（Alex Comfort）。该刊以衰老的机制研究与干预为主，2023 年 1 月起转为完全开放获取，现为每年十二至十四卷，二〇二五年影响因子为 5.1。

Scope

The journal's editorial stance is that ageing has to be studied experimentally: however systematic the observation, a paper must give mechanistic, measurement or intervention evidence about ageing rather than merely describing the clinical features of older people. Clinical case reports are not published. Coverage runs from molecules to populations and concentrates on:本刊的取稿立场是「以实验手段研究衰老过程」：一篇论文不论观察多么系统，都要给出衰老的机制、测量或干预证据，而非仅描述老年群体的临床特征。本刊不发表临床个案报告。收文覆盖从分子到人群的多个层次，重点包括：

• Gerontology and geroscience: evolutionary and comparative biology of ageing, driving mechanisms of ageing, regulation of lifespan and healthspan, and biomarkers of ageing.老年学与老年科学： 衰老的进化与比较生物学、衰老的驱动机制、寿命与健康寿命的调控、衰老生物标志物。

• Cellular and subcellular ageing: cellular senescence and the senescence-associated secretory phenotype, mitochondrial function and autophagy, telomeres and genomic instability, and proteostasis and epigenetic change.细胞与亚细胞衰老： 细胞衰老与衰老相关分泌表型、线粒体功能与自噬、端粒与基因组不稳定、蛋白稳态与表观遗传改变。

• Immunity and endocrinology: immunosenescence and inflammaging, endocrine and metabolic regulation, stress responses and hormonal change, and nutrient-sensing pathways.免疫与内分泌： 免疫衰老与炎症老化、内分泌与代谢调控、应激反应与激素变化、营养感知通路。

• Epidemiology and population studies: cohort studies of older populations, distribution and trajectories of ageing-related measures, environmental and lifestyle factors, and health disparities.流行病学与人群研究： 老年人群的队列研究、衰老相关指标的分布与轨迹、环境与生活方式因素、健康差异。

• Mechanisms of age-related disease: neurodegeneration and cognitive decline, sarcopenia and frailty, bone and joint degeneration, and metabolic and cardiovascular ageing.老年相关疾病机制： 神经变性与认知衰退、肌少症与衰弱、骨与关节退变、代谢与心血管衰老。

• Intervention and translation: pharmacological and non-pharmacological interventions, dietary restriction and exercise, senolytic strategies, and preclinical and clinical assessment of intervention effects.干预与转化： 药物与非药物干预、营养限制与运动干预、清除衰老细胞的策略、干预效果的临床前与临床评价。

History

• Founding (1964): Alex Comfort assembled the first issue in 1964. The founding year is in conflict: most library catalogues date volume 1 to 1965, while this account follows the publisher's official 2008 editorial in giving 1964. The title has not changed since founding.创刊（1964年）： 本刊由（Alex Comfort）于 1964 年编成首期；创刊年存在冲突，多数图书馆目录把第 1 卷记为 1965 年，本稿取出版方 2008 年官方社论的 1964 年口径；刊名自创刊起未变。^[2]

• Open access transition (2023): on 1 January 2023 the journal became fully open access, with all research content free to read on publication and an article processing charge of 3,660 US dollars.开放获取转型（2023年）： 2023 年 1 月 1 日起本刊转为完全开放获取，所有研究内容一经发表即可自由阅读，文章处理费为三千六百六十美元。

• Frequency and metrics: the journal appears as twelve to fourteen volumes a year. The impact factor is 5.1 and the CiteScore 7.7, as queried from the publisher in October 2026. The journal is indexed in the Science Citation Index Expanded, Scopus, MEDLINE and DOAJ.刊期与指标： 本刊现为每年十二至十四卷；影响因子 5.1、引用分数 7.7（出版方 2026 年 10 月查询值）；本刊被科学引文索引扩展版、Scopus、MEDLINE 与 DOAJ 收录。^[1]

Editors

The present editor comes from the University of Florida College of Medicine. The traceable past editors include the founder and several foundational figures in ageing research, and the tenure of one of them is recorded in two versions.本刊现任主编来自佛罗里达大学医学院；历任主编中可考者包括创办人与多位老年学奠基性人物，其中一人的任期年份存在两个版本的记载。^[3]

• Present editor-in-chief: Christiaan Leeuwenburgh of the University of Florida College of Medicine is listed as editor-in-chief in the 2019 volume现任主编： （Christiaan Leeuwenburgh）供职于佛罗里达大学医学院，2019 年卷期已列其为主编；出版方未公布其就任年份。 the publisher does not state the year of appointment.

• Past editors: the founder Alex Comfort served from 1964, Leonard Hayflick from 1985 and Beatrix Grubeck-Loebenstein until 2008. The tenure of Thomas E. Johnson is given in two versions: an obituary says 2008 to 2011, while his own curriculum vitae says August 2008 to 2017, becoming emeritus editor in 2018.历任主编： 创办人（Alex Comfort）自 1964 年起在任；（Leonard Hayflick）自 1985 年起在任；（Beatrix Grubeck-Loebenstein）任职至 2008 年；（Thomas E. Johnson）任期存在两说 —— 讣告称 2008 至 2011 年，其本人履历称 2008 年 8 月至 2017 年、2018 年起为荣誉主编。

• Role in the field: the journal was among the earliest specialist titles in ageing research and has witnessed the shift from descriptive geriatric medicine to mechanistic geroscience. Since becoming fully open access, the visibility of its intervention studies has increased further.学科角色： 本刊是老年科学领域创刊最早的专门刊物之一，见证了衰老研究由描述性老年医学向机制性老年科学的转变；转为完全开放获取后，其干预类研究的可见度进一步提高。
