　　A team of biologists at the University of Virginia School of Medicine confirmed that human social activities may depend on the immune system. According to RNS, the research is currently being published in the journal Nature. Experts have studied the relationship between gamma interferon (an immune system molecule) and mouse behavior. Interferon gamma is produced by the immune system (such as bacteria and viruses).

　　Scientists have shown that the amount of gamma interferon produced during social interaction increases. When tested in laboratory mice, the scientists prevented the production of this substance, and the behavior of this organism was clearly inactive. When the production of γ-interferon resumes, the activity of the organism returns to normal.

　　Scientists pointed out: "The relationship between humans and pathogens directly affects the development of our social behavior, and may allow us to enter the social life we need. In this case, the immune system can create and promote defense against disease."

　　Previously, scientists believed that the nervous system and the immune system were separated from each other.
