As microbes invade the human body, phagocytic cells such as macrophages spring into action to clear the intruders. These cells extend arm-like projections and wrap them around the microbes before ...

Scientists at Trinity College Dublin have discovered that electrically stimulating macrophages can “reprogram” them in such a way to reduce inflammation and encourage faster, more effective healing in ...

Sepsis is a fatal syndrome characterized by life-threatening organ dysfunction originating from a chaotic and unchecked innate immune response to infection. Notably, macrophages are the master ...

Antibodies, which recognize viruses and proteins that the body has encountered before, have long gotten most of the credit for giving the human immune system a memory. Now, researchers at the ...

When cancer cells begin to die within tumors, they expose signals on their surface that indicate they are dying. Macrophages then detect these signals and engage in phagocytosis, where they eat the ...

Scientists identified a gene switch that helps immune cells fully mature, allowing them to clean up tissues and keep our ...
