How the immune system controls the human biological clock in times of infection An important link between the human body clock and the immune system has relevance for better understanding inflammatory and infectious diseases. Researchers report how a critical white blood cell called the macrophage, when exposed to bacteria, makes the biological clock inside the macrophage stop, allowing it to become inflamed.
Dental researchers find some immune cells change to prolong inflammation One of the mysteries of how a small group of immune cells work has been unraveled by researchers: some inflammation-fighting immune cells may actually convert into cells that trigger disease.
Cooperation among viral variants helps hepatitis C survive immune system attacks Warring armies use a variety of tactics, including use of a decoy force that occupies the defenders while an unseen force launches a separate attack that the defenders fail to notice. A new study suggests that the Hepatitis C virus may employ similar tactics to distract the body's natural defenses.
Scientists discover key to what causes immune cell migration to wounds Immune cells play an important role in the upkeep and repair of our bodies, helping us to defend against infection and disease. Until now, how these cells detect a wounded or damaged site has largely remained a mystery. New research has identified the triggers which lead these cells to react and respond in cell repair.
