Neuroinflammation may be a key player in the pathological brain changes produced as a result of chronic opioid use. Microglia is likely responsible for the majority of the changes.
Sustained microglia activation leads to the cells becoming senescent. This leads to an accelerated accumulation of amyloid in the brain, influencing the early stages of Alzheimer's development.
Secondary infections and novel inflammatory events, even ones that occur external to the brain, amplify the brain's immune response and detrimentally impact cognition in mouse models of Alzheimer's disease.
Sevoflurane, an anesthetic, causes tau to leave neurons and enter microglia. This stimulates the production of interleukin-6, leading to inflammation and cognitive impairment.
Microglia creates dense-core plaques which help to clear away more wispy plaques from neurons, preventing cell death. Findings suggest the dense-core plaques play a defensive role in protecting the brain from the ravages of neurodegenerative diseases, such as Alzheimer's.
A new drug modulates, rather than inhibits, a key enzyme implicated in the formation of Alzheimer's related plaques.
Microglia are essential for pruning away extra neural connections in the development of the auditory brainstem.
Microglia appear to play a key role in inflammation-associated depression.
