What Are the Differences Between Acute and Chronic Inflammation?

Acute inflammation is a short-term response to injury or infection, characterized by the rapid influx of neutrophils and the production of inflammatory mediators like histamine. In contrast, chronic inflammation is a prolonged response that involves a different set of cells, primarily lymphocytes and macrophages, and leads to tissue remodeling and fibrosis. While acute inflammation aims to eliminate the initial cause of injury and promote healing, chronic inflammation often results in ongoing tissue damage and repair.
