There is a type of white blood cell called a dendritic cell, which normally chews up and destroys invading microbes.
Inflammation occurs when the body rallies to defend itself against invading microbes or to heal damaged tissue.
The researchers said the Nod2 gene was found in primitive defense cells called monocytes that engulf invading microbes.
When bound to transferrin, however, iron is unavailable to the invading microbes, and their growth is stemmed.
In it were antibodies, Y-shaped molecules that are produced naturally by the immune systems of mammals as a defense against invading microbes.
Dendritic cells lie in wait, ready to greet and capture invading microbes like H.I.V., the AIDS virus, that enter through the mucosa.
By attaching themselves to some invading microbes, other antibodies can render such microorganisms immobile or prevent them from penetrating body cells.
Microbial infections can spark NETosis, leading to an unleashing of anti-microbial net trap that target invading microbes such as bacteria, viruses, parasites or fungi.
Drosophila melanogaster, like other invertebrates, relies solely on its innate immune response to fight invading microbes; by definition, innate immunity lacks adaptive characteristics.
Many of the mechanisms that spring into action to destroy invading microbes switch gears to cart away dead cells and repair damaged ones.
Plants have a multi-layered immune system that confronts invading microbes with a barrage of stressors, preventing growth of most microbes.
