Chronic inflammation and cellular senescence create a self-perpetuating cycle during aging
In short: A review of aging research describes a two-way loop between inflammation and cellular aging known as 'inflammaging.' Senescent cells release factors that drive chronic inflammation, and that inflammation in turn speeds up the aging of immune cells, weakening the body's ability to clear senescent cells and inflammatory signals, which the authors link to organ damage and age-related disease.
The review frames this feedback loop—dubbed inflammaging—as a key driver of organ dysfunction and immune decline with age, and argues that reducing chronic inflammation could be a strategy worth exploring against aging-related disease.
As a review, it synthesizes existing research rather than reporting a new experiment, so it doesn't test this idea with new data of its own.
Why it matters: Understanding how inflammation and cellular aging reinforce each other could help guide future research into anti-aging strategies.
