Neuroimmunology delves into the intricate interplay between the immune system and the nervous system, examining how immune responses impact neurological function and disorders. It investigates phenomena like neuroinflammation, autoimmune reactions targeting the CNS, and the role of immune cells and molecules in neurological diseases. Neurotransmitters, on the other hand, are vital chemical messengers that facilitate communication between neurons, regulating diverse functions like mood, memory, and pain perception. Imbalances in neurotransmitter levels are implicated in various conditions, from depression and anxiety to Parkinson’s disease and schizophrenia. Both fields are pivotal in unravelling the complexities of brain health and disease, paving the way for innovative therapeutic strategies.
