Cytokine Storm

Meaning

A severe and potentially life-threatening systemic inflammatory syndrome characterized by the rapid and massive release of pro-inflammatory cytokines, chemokines, and other mediators by immune cells. This uncontrolled and exaggerated immune response overwhelms the body’s regulatory mechanisms, leading to widespread tissue damage, multi-organ failure, and systemic shock. It represents a critical dysregulation of the body’s finely tuned inflammatory response.
