Latest Macrophages Stories
Based on experiments with Mexican salamanders, researchers have found that elements of a salamander’s immune system called macrophages play a key role in enabling the regenerative process.
"At present, researchers know very little about exactly how microglia work. At the same time, there is a lot of curiosity and high hopes among brain researchers that greater understanding of microglia could lead to entirely new drug development strategies for various brain diseases", says Johan Jakobsson, research group leader at the Division of Molecular Neurogenetics at Lund University.
In many pathologies of the nervous system, there is a common event - cells called microglia are activated from surveillant watchmen into fighters.
Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found.
Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons.
Macrophages play a key role in the immune response, protecting organisms against infection and regulating the development of inflammation in tissue.
The theory that pigeons' famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.
Microglia are the first line defence of the brain and are constantly looking for infections to fight off.
Sometimes our immune defence attacks our own cells.
