 the study examined the interactions between the immune system and the brain. It found that certain immune cells, such as NK cells and innate lymphoid cells, play a role in regulating brain function by influencing the production of neurotransmitters and the formation of memories. Specifically, it was discovered that these cells produce interferon gamma, which helps to form non-spatial memories, and acetylcholine, which regulates anxiety-like behaviors. This research provides insight into how the immune system interacts with the brain, and could lead to new treatments for disorders related to immunity and cognition.
