Neuroimmune diseases are disorders arising from abnormal interactions between the nervous and immune systems. These diseases can cause neurological symptoms such as paralysis, sensory loss, and cognitive impairment. Mechanisms often involve autoimmunity, neuroinflammation, and disrupted blood - brain barrier function. Current research focuses aim to understand immune cell infiltration into the nervous system and the effects of cytokine - mediated damage, with the goal of developing immunomodulatory therapies to improve patient outcomes.
