Regulating Systems in Neuroimmunology

Abstract

Neuroimmunology is the study of the interaction between the immune system and nervous system during development, homeostasis, and disease states. Descriptions of neuroinflammatory diseases dates back centuries. However, in depth scientific investigation in the field began in the late 19th century and continues into the 21st century. Contrary to prior dogma in the field of neuroimmunology, there is immense reciprocal crosstalk between the brain and the immune system throughout development, homeostasis, and disease states. Proper neuroimmune functioning is necessary for optimal health, as the neuroimmune system regulates vital processes including neuronal signaling, synapse pruning, and clearance of debris and pathogens within the central nervous system. Perturbations in optimal neuroimmune functioning can have detrimental consequences for the host and underlie a myriad of physical, cognitive, and behavioral abnormalities. As such, the field of neuroimmunology is still relatively young and dynamic and represents an area of active research and discovery.
