^{Immunology and Oncology}

Neuroimmunology is a field combining neuroscience, the study of the nervous system, and immunology, the study of the immune system. Neuroimmunologists seek to better understand the interactions of these two complex systems during development, homeostasis, and response to injuries. A long-term goal of this rapidly developing research area is to further develop our understanding of the pathology of certain neurological diseases, some of which have no clear aetiology. In doing so, neuroimmunology contributes to the development of new pharmacological treatments for several neurological conditions. Many types of interactions involve both the nervous and immune systems including the physiological functioning of the two systems in health and disease, malfunction of either and or both systems that lead to disorders, and the physical, chemical, and environmental stressors that affect the two systems on a daily basis. We know both the nervous system and the immune system plays a major role in humans life. One as a signal system and one as a protective system.
