動畫導讀:這支動畫在演什麼What you're watching
- 顯微鏡下的腸道腔室中,多樣的桿狀細菌正在將膳食纖維轉化為發光的微小球體。
- 發光球體穿過半透明的腸道細胞壁,並進入搏動中的紅色血管。
- 在大腦微血管內,球體沿著血管壁移動並滲透進緻密的波浪狀血腦屏障。
- 發光球體出現在屏障的神經側,並與分支狀的微膠細胞及星狀細胞表面的受體結合。
- A microscopic view of the gut lumen where diverse rod-shaped bacteria are fermenting dietary fiber into small, glowing spheres representing short-chain fatty acid metabolites
- The glowing spheres migrate from the intestinal environment through a semi-permeable cellular wall and enter a pulsing red blood vessel
- Inside a brain capillary, the spheres travel along the vessel wall and begin to penetrate a dense, wavy protective structure representing the blood-brain barrier
- The spheres emerge on the neural side of the barrier and bind to specialized receptors on the surfaces of branching microglia and star-shaped astrocytes
