The brain has its own equivalents of gardeners called microglia.

大脑的园丁叫作”小神经胶质”。

It's thought the microglia like a gardener too keen with shears, trim the wrong brain connections.

它能够像园丁一样拿着剪刀修剪细胞之间的错误联系。

The brain has immune cells known as microglia that are supposed to maintain health by removing waste.

脑中含有被称为微小胶质细胞的免疫细胞，它们通过清除代谢废物的方式保持脑的健康。

A team of UK medical research council scientists found the microglia was too keen in schizophrenia.

英国医学研究委员会的科学家发现，小神经胶质对精神分裂症的反应尤为灵敏。

Microglia are immune cells that clear out waste and prune synapses during development.

小胶质细胞是在发育过程中清除废物和修剪突触的免疫细胞。

Our microglia janitor cells become hyper-activated, releasing chemicals that cause inflammation and cellular damage.

我们的小胶质细胞看门细胞变得过度活跃，释放出引起炎症和细胞损伤的化学物质。

Normally, amyloid beta is cleared away metabolized by microglia, the janitor cells of our brains.

通常， β 淀粉样蛋白被小胶质细胞（我们大脑的看门细胞） 代谢清除。

The microglia also start to remove synapses by phagocytosis.

小胶质细胞也开始通过吞噬作用去除突触。

Neurons aren't the only cells affected in Alzheimer's disease; astrocytes and microglia also play a role.

神经元并不是阿尔茨海默病中唯一受影响的细胞。星形胶质细胞和小胶质细胞也发挥作用。

Microglia take up Abeta, but, they also get activated by it, triggering the release of inflammatory cytokines that can damage neurons.

小胶质细胞吸收 Abeta，但它们也会被它激活，从而引发可损害神经元的炎症细胞因子的释放。

And a paper published in April this year found that boosting neurogenesis also caused other cells known as microglia to begin cleaning up tangles of protein, called amyloid-beta plaques, that are characteristic of Alzheimer's disease.

今年4月发表的一篇论文发现，促进神经发生也会导致其他小胶质细胞，开始清理淀粉样蛋白斑块的蛋白质缠结，这是阿尔茨海默病的特征。
