Chronic inflammation

Hallmark of aging179 papers42 findings

In humans, chronic inflammation is associated with upper gastrointestinal cancer and pneumonia. Multiple pharmacological, genetic, and cell therapies suppress it in mice and rats, whereas microplastics, aged neutrophils, and Chek2 promote it in rodent and human cells.
