Acute Inflammation


The acute inflammatory response is activated by infectious agents and/or damaged tissues. These trigger vascular and cellular responses to deliver cells and proteins to the site of cell injury.

Key steps of acute inflammation:

1. Recognition of inflammatory agents by host cells.
2. Leukocyte and plasma protein recruitment from the blood to the tissues.
3. Leukocyte activation at the site of injury.
4. Control and termination of inflammation to avoid harming healthy cells.
