He infected a cell with MRSA under a microscope and inserted a dye that would glow in the presence of ROS. Mitochondria in the infected cell began to glow, as did the macrophage when the bacteria ...

Most dangerous bacteria are attacked by macrophages. The macrophage engulfs bacteria and immediately traps them in a separate cell compartment, or vesicle. This vesicle is called a phagosome and ...

The researchers also discovered that when these cells, called macrophages, eat live bacteria it triggers an inflammation response. But when they eat dead bacteria it doesn’t. “When phagocytic cells ...

The team found that, unlike live bacteria, dead bacteria contained 3′,5′-cyclic adenosine monophosphate (cAMP) and released a byproduct of this metabolite upon phagocytosis by macrophages. This in ...

When the macrophages were exposed to live bacteria, the researchers observed that they triggered strong inflammatory responses characterized by high levels of TNF-α, IL-6, and IL-1β.
