When cells die or the body no longer needs them, phagocytic cells arrive to engulf them. This process relies upon the cells destined for destruction to express a protein that serves as an “eat me” ...

Phagocytosis is a fundamental cellular process by which specialised immune cells ingest and eliminate particulate matter, including pathogens, apoptotic cells and debris. Professional phagocytes such ...

Macrophages and other immune cells are the natural frontline immune warriors of our body, defending the body against invading pathogens and cancer cells. Yet despite their innate "combat" capabilities ...

Every day, billions of damaged or unnecessary cells die and are swept away by the immune system’s cleanup crew—phagocytes. But when that clearance falters, dangerous cells can linger, fueling cancer ...

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 the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have discovered a previously unknown function of immune cells in the bone marrow. Embryonic macrophages—specialized ...
