Macrophages are cells in the immune system that belong to the phagocyte family, or so-called scavenger cells
. They reside in almost all tissues of the body, for example in the small intestine, liver, brain, and skin.
They include monocytes, which are large white blood cells that can differentiate into scavenger cells
macrophages and dendritic cells in response to inflammatory signals.
As it will be further discussed, glia are the scavenger cells
of the brain.
This amazing defense system deploys scavenger cells
that constantly travel throughout the body, identifying, and often digesting foreign substances that pose a threat to us.
The latest technology sees lasers used to break of particles of ink into tiny fragments, which are then taken away by scavenger cells
in the skin, causing the tattoo to fade and eventually disappear.
At the same time, a group of support cells called glia and scavenger cells
called microglia accumulated in the hypothalamus and appeared to become activated.
In the new study, 12 patients will be treated with healthy scavenger cells
, created in a laboratory from human embryonic stem cells.
