你知道吗
你健康，是因为你的细胞健康
你元气满满，是因为你的细胞活力满满
你生病了，却又慢慢的好起来
是因为你的免疫细胞殊死搏斗，
杀死了入侵的病原体
Do you know you are healthy
because your cells are healthy？
You're sick, but you're getting better.
It's because your immune cells
kill the invading pathogens.
所以说
最好的医生就在人体内
它就是由免疫细胞等组成的免疫系统
也就是大家统称的“免疫力”
So, the best doctor
is in your body.
It's called immunity.
免疫细胞的作用和分工
Immune cells are cells involved in or related to immune response. It mainly includes neutrophils, eosinophils and basophils, monocytes, lymphocytes, etc.
作用是杀灭细菌和病毒、清除体内癌变、病变和衰老的细胞，延缓机体衰老，并且监视身体的稳定，就像身体里的军队，保护我们的安全。
Its function is to kill bacteria and viruses, remove cancer, pathological changes and aging cells in the body, delay the aging of the body, and monitor the stability of body.
1、免疫细胞就像一个国家的军队
There are 3-9 billion immune cells per liter of blood.
免疫细胞的主要功能是消灭外敌，防止内乱。如果突然白细胞失能（非极端情况如艾滋病人T淋巴细胞损坏），就会得各种五花八门的病然后夺走我们的生命。
The main function of immune cells is to eliminate foreign enemies and prevent internal disorder.
各种细胞生活在一个复杂的大环境里，总会互相帮助， 免疫细胞就像一个国家的军队，虽然人数占总人口的比例并不大，但是如果没有他们，在一个弱肉强食、内忧外患的世界，就会被别人欺负。当然，由于他们具有巨大的能量，管不好他们也许会发生更大的灾难，各种自身免疫疾病就是免疫细胞引发的灾难。
Immune cells are like the army of a country. Because of their huge energy, mismanagement of immune cells can lead to greater disaster. All kinds of autoimmune diseases are caused by immune cells.
2、免疫系统的分工合作
吃货：中性粒细胞
免疫细胞部队有五大兵种。直接面对敌人的主要是中性粒细胞，必杀技就是吃吃吃。
There are five major branches of the immune cell force. The main one facing the enemy directly is neutrophils.
▲中性粒细胞穿壁过程
总参谋：淋巴细胞
Lymphocyte is equivalent to commander in chief.
预备役部队：单核细胞
单核细胞作为预备役部队，一旦巨噬细胞减员不足，立即打鸡血分化变身，参与组织器官中与病原体的巷战。
As a reserve force, monocytes will take part in the battle between pathogens and tissues in case of insufficient macrophages.
嗜酸性粒细胞和嗜碱性粒细胞
Almost all diseases are related to the deficiency of immune cell activity.
免疫细胞减少、活力不足，则会表现出经常感到疲惫、精神恍惚、心慌气短、感冒不断且反复发作，易感染，伤口不易愈合等症状。
If the immune cells are reduced and lack vitality, human body will appear some symptoms, such as fatigue, trance, panic, shortness of breath.
1、肺部与免疫细胞
如果肺部免疫细胞活力降低，将直接导致咳嗽、感冒、气喘、慢性支气管炎等疾病。
If the activity of lung immune cells is decreased, it will directly lead to cough, cold, asthma, chronic bronchitis and other diseases.
2、肠道、胃部与免疫细胞
人体70%免疫细胞集中在肠道和胃部，肠胃免疫细胞减少，致使进入肠胃的毒素、病菌无法清除，肠胃炎、胃痛、胃溃疡集中爆发。
If the number of immune cells in the intestine and stomach is reduced, it will lead to gastroenteritis, stomachache and gastric ulcer.
3、血液与免疫细胞
血液中的免疫细胞减少，病毒在血管滋生“长垢”，导致血管内血糖、血脂代谢紊乱，诱发糖尿病、高血脂、高血压等。
The immune cells in the blood are reduced, which leads to the disorder of blood glucose and lipid metabolism in the blood vessels, and induces diabetes, hyperlipidemia, hypertension, etc.
4、肝脏、肾脏与免疫细胞
负责解毒的肝脏和负责生津、排泄的肾脏，免疫细胞缺失的话，毒素淤积，功能受损，女性常表现为脸上长黑斑，男性常腰酸乏力、夫妻生活不和谐……
If the immune cells in the liver and the kidney are reduced, the toxin will accumulate and the function will be damaged.
与之相反的是，发表在《美国国家科学院院刊（PNAS）》杂志，对超百岁老人（超过110岁）的研究发现：这些老人存在着一种罕见的“超级”免疫细胞。这些免疫细胞的浓度是普通人的9倍，可能会保护超百岁老人免受病毒和肿瘤的侵袭，使他们在漫长的一生中保持非常良好的健康状态。
A study published in the National Academy of Sciences found that centenarians (over 110 years old) have a kind of rare "super" immune cells. The concentration of these immune cells is 9 times of that of ordinary people, which may protect the centenarians from the invasion of viruses and tumors, and keep them healthy for a long life.
由此可见，免疫细胞就是人体与病菌战斗的先锋。
Immune cells are the vanguard of the battle between human body and pathogens.
▲免疫细胞与病毒在体内的激烈战争
战败=生病 衰老
战胜=健康 长寿
如果想要老而无病，
健康长寿，年轻美丽
请提高我们的免疫力
If you want to live
a long and healthy life,
please improve own immunity.
