Abstract
Aim
Aging and age-related diseases are an ever-increasing social and public health problem. Allostatic load (AL) shows great potential as an interdisciplinary tool for assessing the aging of human beings but as yet lacks investigation in animal models which is our study focus at.
Methods
Here a continuous study of AL was conducted on naturally aging rats. Blood samples were collected from the rats at ages of 5, 8, 14, 18, and 21 months. Dozens of blood biochemical indicators, including serum corticosterone, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, C-reactive protein, interleukin-6, 25-hydroxyvitamin D, free fatty acid, CD3+ T cell count, CD4+/CD3+ T cell ratio, CD8+/CD3+ T cell ratio, and CD3/4/8+ T cell apoptosis, were determined.
Results
AL was scored from those indicators, and we found that AL score gradually increased with age.
Conclusions
AL can reliably reveal the cumulative and systemic changes in aging. Geriatr Gerontol Int 2024; 24: 1077–1084.
期刊介绍:
Geriatrics & Gerontology International is the official Journal of the Japan Geriatrics Society, reflecting the growing importance of the subject area in developed economies and their particular significance to a country like Japan with a large aging population. Geriatrics & Gerontology International is now an international publication with contributions from around the world and published four times per year.
