Scientists from the University of Southampton have identified the molecular system that contributes to the harmful inflammatory reaction in the brain during neurodegenerative diseases.
An important aspect of chronic neurodegenerative diseases, such as Alzheimer's, Parkinson's, Huntington's or prion disease, is the generation of an innate inflammatory reaction within the brain.
Results from the study open new avenues for the regulation of the inflammatory reaction and provide new insights into the understanding of the biology of microglial cells, which play a leading role in the development and maintenance of this reaction.
Dr Diego Gomez-Nicola, from the CNS Inflammation group at the University of Southampton and lead author of the paper, says: "The understanding of microglial biology during neurodegenerative diseases is crucial for the development of potential therapeutic approaches to control the harmful inflammatory reaction. These potential interventions could modify or arrest neurodegenerative diseases like Alzheimer disease.
"The future potential outcomes of this line of research would be rapidly translated into the clinics of neuropathology, and would improve the quality of life of patients with these diseases."
Microglial cells multiply during different neurodegenerative conditions, although little is known about to what extent this accounts for the expansion of the microglial population during the development of the disease or how it is regulated.
