The body is pretty amazing in how it can detect foes. The system is literally called "friend/foe" and it is the immune system's response to all bacteria. Researchers examined mice for a particular strand of bacteria known as Helicobacter hepaticus. This invader caused a response from T cells and immediately was acted upon as "foe." Specifically Th17 were the T cells that were able to kill the bacteria, but they have another which shuts this cell down when finding friendly ones, not causing the inflammation chain that it normally does.
- T-cell helper 17, or Th17, are the main cells who cause inflammation to kill cells
- These cells seem to be able to be "turned off" when in contact with other cells that are safe.
- This response is known as "Friend/foe" in the immune system and explains why some bacteria are not killed on sight.
"Certain bacteria, such as those from the Helicobacter family, are generally considered helpful but can cause disease when genetic or environmental factors alter the normal balance."
