Neuroimmunology and Neurodegenerative Diseases

Neuroimmunology is a research field that explores the intricate relationship between the nervous system and the immune system. It investigates how immune cells—either those that enter the brain from the bloodstream or microglial cells that reside within the brain—respond to neurological injury, disease, or the natural aging process. These immune responses can help preserve brain function or, in some cases, contribute to its decline.

Neurodegeneration refers to the progressive deterioration and death of nerve cells in the brain and nervous system, as seen in disorders such as Alzheimer's disease, Parkinson's disease, and multiple sclerosis. These processes often result in the loss of critical functions such as memory and motor control.

By studying the immune mechanisms involved in brain inflammation and degeneration, neuroimmunology offers insights that may lead to the development of new therapeutic approaches.
