Neuroinvasion

Neuroinvasion refers to the process by which harmful agents, such as viruses or bacteria, enter and spread within the nervous system, particularly the brain and spinal cord. This allows the infection to bypass the usual protective barriers, like the blood-brain barrier, and directly affect neural tissues. Neuroinvasion can lead to inflammation, damage, or dysfunction in the nervous system, resulting in various neurological symptoms. It is a critical step for many pathogens to cause serious neurological diseases, and understanding this process helps in developing targeted treatments and preventive measures.
