A s 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 ...

The host cell and intracellular pathogens are in a continuous struggle. Flannagan, Cosío and Grinstein describe the pathway by which the bacteria are taken up, the antimicrobial mechanisms of the ...

When circulating phagocytic cells attempt to engulf and kill the pathogen, Yersinia’s T3SS injects a set of at least four effectors that collectively paralyze the phagocytic machinery before the ...

In phagocytosis, phagocytes engulf large prokaryotic cells, such as bacteria, or eukaryotic cells, such as yeast cells or dead cells (>0.5 µm) to kill them, or small particles to remove them from ...

In diseases due to exposure to toxic particles like gout, macrophages elicit separate pathways for inflammation and lysosomal ...

The teams found that bacteria that are able to destroy or subvert phagocytes -- the cells of the immune system that engulf bacteria -- have ID50 of around 250 cells.

It is also a crucial mechanism of defense against pathogens, ... To make it easy for patrolling phagocytes to home in and engulf apoptotic cells, ...

The human body has three primary lines of defense to fight against foreign invaders, including viruses, bacteria, and fungi. The immune system’s three lines of defense include physical and ...

One feature of the fruit fly's innate immune system is the presence of circulatory cells called phagocytes that, like our own white blood cells, engulf and digest bacteria.

Phagocytes are the white blood cells that protect the body by ingesting (phagocytosing) harmful foreign particles, bacteria, and dead or dying cells. Their name comes from the Greek phagein, "to ...
