Research suggests that microglial synapse elimination may play a role in the pathogenesis of various neurological diseases, including Parkinson's disease, Alzheimer's disease, and Huntington's disease. The complement system, including complement receptor 3, has been implicated in this process. The relationship between microglia, synapse elimination, and neuroinflammation is being explored in the context of these diseases, with studies examining the mechanisms and potential therapeutic implications.
