Researchers say they have found four new types of human blood cell in a study that could rewrite biology textbooks.
The newly found cells play a role in the body’s immune system and help our bodies to fight off invaders.
Researchers found the new white blood cells using new genetic techniques, but the exact functions of the newly discovered units remain a mystery.
NEW BLOOD CELLS
Four new types of human blood cell have been discovered by scientists.
They found two new dendritic cells, the units that raise the alarm during an infection.
When a dendritic cell comes across an invader, it takes in a fragment of that invader and displays it on its cell surface.
By doing this, dendritic cells act as messengers, telling other white blood cells that the body is under attack.
