Understanding Tattoos and the Immune System
每个纹身下都藏着一座墓地， 而你的
免疫系统其实正是将 墨水困住的关键。
针头将色素刺入你的 皮肤深处，直达
真皮层。
你的身体立刻将它视为外来 入侵者。
巨噬细胞，这种强大的免疫细胞， 会蜂拥而至，吞噬这些
色素。
但纹身墨水极其顽固。
它们无法将其摧毁，
所以墨水就被困在它们体内。
最终，巨噬细胞死去。
暂时看来， 身体似乎终于赢了，
但其实没有。
色素被释放出来， 另一巨噬细胞赶来
再次将其捕获。
一个细胞死亡，另一个接手。
死亡、释放、捕获，周而复始。
这种微观循环可持续 数年。
部分色素会逐渐通过 淋巴系统逃逸，这也是
纹身会慢慢褪色的原因之一。
但大部分色料仍被困在这 无尽的细胞循环中。
所以，你皮肤上的那处纹身，
并非只是静静待在那里。它 不断被捕获，
被释放， 又被你的免疫系统重新捕获。
一场在你皮肤下发生的微观战斗， 你永远
也看不见。
关注Lificle。 还有更多奥秘等待你去发现。

Original transcript (English)
Every tattoo has a hidden graveyard beneath it, and your immune system is actually what keeps the ink trapped. The needle forces pigment deep into your skin, into the dermis. Your body immediately sees it as a foreign invader.
Macrophages, powerful immune cells, rush in and swallow the pigment. But tattoo ink is incredibly stubborn. They can't destroy it, so the ink stays trapped inside them.
Then eventually, the macrophage dies. For a moment, it looks like your body has finally won, but it hasn't. The pigment is released and another macrophage arrives and captures it again.
One cell dies, another takes over. Death, release, capture, repeat. This microscopic cycle can continue for years. Some pigment gradually escapes through the lymphatic system, which is one reason tattoos slowly fade.
But much of the ink remains caught in this endless cellular cycle. So that tattoo on your skin, it isn't simply sitting there. It is being constantly captured, released, and captured again by your immune system. A microscopic battle happening beneath your skin that you'll never
see. Follow Lificle. There's so much more to discover.
