This article is about scientists discovering how our immune systems fight off bacteria and viruses to protect or bodies. The research relating to the discovery will lead to the development of drugs and vaccines that could prevent people from suffering from many illnesses. This finding was made by an immune cell that attacks malicious invaders. They wanted to figure out if a molecule or a synthetic molecule would stimulate production among a cell. Yet, the results showed that bacteria and viruses activate the body's defense system.

In my opinion, I think our bodies have a lot of bacteria that could harm our bodies. Antibotics can only kill bacteria for a certain amount of time. Scientists need to find cures to common illnesses, like the common cold. They also need to prevent bacteria from hacking our immune system. Even if bacteria can find alternative pathways into our immune system, they needed to be treated permanently.
