Frontiers editorial spotlights inflammaging in animal aging

A new Frontiers in Veterinary Science editorial is putting “inflammaging” back in focus for veterinary medicine, arguing that chronic, low-grade inflammation linked to cellular senescence may be a common pathway behind age-related disease in dogs, cats, and horses. The editorial by Toshiro Arai was accepted March 30, 2026, and anchors Frontiers’ “Unraveling inflammaging” Volume II research topic, which also includes papers on feline obesity and inflammaging, senior-dog nutraceuticals, and breed- and age-related periodontal disease risk. The piece frames prevention around earlier biomarker development, nutritional strategies, and emerging regenerative approaches such as stem cell therapy, rather than waiting for late-stage chronic disease to declare itself.

Why it matters: For veterinary professionals, the editorial reflects a broader shift toward geriatric care that is less organ-by-organ and more systems-based. That matters because recent veterinary literature suggests inflammaging may contribute to common late-life problems across species, but also shows how unsettled the biomarker question still is. A 2024 Frontiers study in healthy small dogs found some metabolic and oxidative markers changed with age, while serum amyloid A measured by latex agglutination did not perform well as an age-related inflammation marker in clinically healthy dogs. A recent JVIM narrative review similarly notes that evidence in dogs and cats is growing, but practical, validated biomarkers and intervention standards remain limited. (frontiersin.org)

What to watch: Expect more follow-on work on usable screening biomarkers, nutrition-based interventions, and whether anti-inflammatory or regenerative strategies can move from theory into routine senior-pet protocols. (frontiersin.org)
