Neuroimmunology is a field that focuses on the interactions between the nervous system and the immune system. It explores how immune responses can affect the function of the nervous system and vice versa. This interdisciplinary field examines how the immune system can influence neurological conditions such as multiple sclerosis, Alzheimer's disease, and Parkinson's disease, as well as how the brain can regulate immune responses. Researchers in neuroimmunology investigate the role of immune cells, cytokines, and other immune molecules in the development and progression of neurological disorders, with the goal of developing new treatments and therapies for these conditions.
