    The intestine is home to trillions of microbes.
    Most microbes coexist peacefully with our own cells, help us obtain energy from food, and provide essential nutrients that we cannot make ourselves
    .
    Intestinal wall cells separate these microorganisms from other parts of the body, just like the "Great Wall" of our body kingdom
    .
    Inside the Great Wall, heroes with a powerful immune system guard us and protect us
    .
    But how does the immune system distinguish between our own cells and gut microbes? How to distinguish the relationship between beneficial microorganisms and pathogenic microorganisms? This is an amazing story, full of secrets
    .


    The intestine and microbes are old friends.
    The

    intestine is a long tube inside the body, from the mouth to the anus, including the stomach, small intestine, and large intestine
    .
    They are one of the oldest organs in our evolution, and they are experts in providing food and water for the rest of our cells
    .
    However, they cannot provide all the nutrients and energy we need to survive
    .
    In the process of evolution, our intestines provide a perfect home for microorganisms: a warm environment, adequate food, and protect them from the outside world
    .
    We also benefit from these microorganisms because they can also help break down food and produce some nutrients that the intestines cannot provide
    .
    The friendship between the gut and intestinal flora helps humans stay healthy
    .


    Immune cells: The superhero of the body

    When we eat and drink, the substances entering the intestine may bring potential enemies, such as pathogenic bacteria and viruses
    .
    The immune system protects us from these invaders by fighting infections
    .
    However, it is important that immune cells cannot attack friendly cells, otherwise, the immune system will kill our own cells and our ally-the intestinal flora
    .
    This is their true super power, something they can only obtain through hard study and practice
    .


      The immune system is like an army composed of many professional soldiers:

      First, we have a kind of "warriors" called granulocytes, which are the first line of defense of the immune system
    .
    These cells are the fastest fighters, armed with toxic particles to attack infectious invaders
    .
    Granulocytes do not have a long lifespan and only require limited training because they are born to attack the enemy
    .
    The toxic particles they release attack everything around, so they can also damage friendly cells
    .


      Second, we have a kind of "gatekeeper" called phagocytes, which can swallow invading organisms
    .
    They are also teachers of the immune system and are important for identifying whether microorganisms are good or bad
    .
    Once they do this, the phagocytes will alert the rest of the immune cells and teach them to recognize harmful microorganisms
    .


      Third, the generals of the immune system are called lymphocytes
    .
    Lymphocytes are trained by phagocytes to remember all microorganisms and coordinate the immune system's response
    .
    Some lymphocytes become experts in identifying specific enemies and help speed up attacks
    .
    Other lymphocytes learn to recognize their peers and send messages to stop the army from attacking
    .


      Thanks to lymphocytes, the immune system can learn from the first battle with an infectious invader and react faster when the same invader attacks a second time
    .
    This is called immune memory
    .
    This is also the function of vaccination to train our lymphocytes
    .
    Some enemies are really powerful, so we don’t want the immune system to fight these without proper training
    .



      Intestinal microbes include bacteria, viruses and even worms.
    Some of these microbes are our friends, and some are very dangerous.
    Intestinal cells use a layer of mucus to protect themselves.
    They form a "Great Wall" that separates the microbes from other parts of the body.
    Separate; the heroes of the immune system protect our bodies: granulocytes (front-line fighters), phagocytes (teachers of gatekeepers and lymphocytes), lymphocytes (generals that distinguish between enemies and friends)
    .


      The training of the immune system in the intestine  The intestine

      with various microorganisms is the best school for training the immune system
    .
    Intestinal wall cells separate microorganisms from the rest of the body, but they also protect themselves by the protective mucus that covers their surface
    .
    On this Great Wall of the Intestine, the heroes of the immune system are always observing and studying the microbes in the intestine
    .
    Sometimes, intestinal cells will show immune cells some microorganisms living in the intestine; other times, immune cells will extend their "arms" through the intestinal wall to study the microorganisms trapped in mucus
    .
    This is how immune cells become smarter, stronger, and ready to fight any danger
    .
    We can't see or feel this, but when the immune system recognizes the microorganisms, there is always a fight about to begin
    .
    However, most gut microbes are beneficial, and lymphocytes also know this, so they calm the fighters
    .
    In addition, as long as the microbes and other parts of the body are separated by the Great Wall of the intestine, the intestine will remain peaceful
    .


      How do immune cells distinguish body cells and beneficial microorganisms from harmful microorganisms? Our body cells are easy to recognize because they all have the same molecules on their surfaces, just like a football team wearing the same color jersey
    .
    These molecules are very different from those on the surface of microorganisms
    .
    Granulocyte "warriors" and phagocyte "gatekeepers" can detect specific molecules on microorganisms.
    However, beneficial and harmful microorganisms have very similar molecules on the surface, so it is difficult to distinguish good from bad by these molecules.

    .
    However, some beneficial bacteria will produce other molecules to send peaceful messages to the immune system, so that the immune system can distinguish these microorganisms
    .
    These molecules are like microbes saying "Hello, friend, I'm here to help!"
    .
    There is still a lot of such secret information in the gut, and scientists are working hard to discover it
    .


      Superheroes also "play hooligans.
    "

      Sometimes, things may not go well and the intestines may be infected
    .
    Many years ago, sanitary conditions were worse than they are now, houses were not clean, and food and water often contained pathogenic microorganisms
    .
    This means that people are more likely to get sick from ingesting harmful microorganisms
    .
    Every time they get sick and recover, the immune system is better trained to fight them
    .
    Even if infected by some microorganisms that can resist this kind of resistance, such as worms, the immune system will learn how to repair the damage they cause
    .
    Therefore, in any case, people can recover from future infections more quickly
    .


      Today, however, our way of life is very different, and we have solved many of the problems of the past
    .
    We have antibiotics to kill the enemies who infect us
    .
    Our homes, food and water are cleaner, and it is unlikely that we will get sick
    .
    Together, these changes have changed our intestinal environment, intestinal flora and immune system
    .
    Now, dangerous enemies do not have as many opportunities to infect us as before
    .
    But this is also a bit "boring" for the immune system.
    Our microbial community contains fewer enemies, but there are fewer types of beneficial bacteria
    .
    When we take antibiotics, our beneficial bacteria and pathogenic bacteria are killed
    .
    Our diet has also undergone tremendous changes, which is also changing our intestinal flora
    .
    All these changes are misleading our immune system superheroes and interfering with their training
    .


      All these small changes in lifestyle combine to create "boring" and "confused" immune cells, which is not a good thing: they may start fighting, but they don’t know when to stop; sometimes they even attack the body’s own cells
    .
    The undertrained immune system superhero turns into a rogue villain
    .
    Infectious diseases have decreased, but they have led to a variety of new types of diseases, including allergies, inflammatory bowel disease, arthritis, psoriasis, diabetes, obesity, depression, cardiovascular disease and even cancer, etc.
    These are all modern society Very common disease
    .
    In fact, most of these diseases are related to changes in immune system superheroes and their intestinal training camps
    .
    These modern diseases are very complicated, because even in people with the same lifestyle, not everyone will get sick
    .
    This is because all individuals are different, not only in characteristics such as hair color or height, but also in the way cells work
    .


      The magical story that happened in the gut

      (A) Immune cells can recognize them through the peace-keeping molecules produced by beneficial bacteria
    .


      (B) If the microorganisms are friendly, General Lymphocytes can calm the soldiers down
    .


      (C) Antibiotics help kill disease-causing bacteria, but they can also kill beneficial bacteria
    .


      (D) Intestinal cells form a barrier to keep microorganisms out of the body
    .


      (E) When the barrier is broken, immune cells will lend a helping hand
    .


      (F) Unfortunately, certain aspects of modern life cause immune cells to fight against the body's own cells
    .


      Conclusion

      For us and our intestinal flora, the world is changing
    .
    But don’t worry too much, we can do many things to take care of our intestinal flora and let it continue to effectively train our immune system: bad bacteria like sweets and junk food very much, so if you can, replace sugary foods with Fruits and vegetables, fresh, natural, unprocessed, and real food will also help our beneficial bacteria grow and protect us; use antibiotics carefully, if not necessary, and resolutely do not; wash hands before meals, but do not pay too much attention to cleanliness, this Enough to avoid most infections
    .
    If we pay more attention to these things, there is no need to worry too much, we can trust our immune system superheroes
    .


      Remember, the intestine is a training camp for the immune system.
    Our diet and lifestyle affect our intestinal environment and determine whether the immune system becomes a superhero or a rogue villain
    .
    Each of us has the ability to transform the immune system into a superhero, and we also have the weakness of transforming it into a rogue villain
    .
    Maintaining a healthy intestinal training camp environment can provide a superhero to protect our physical and mental health
    .

    In addition, as long as the microbes and other parts of the body are separated by the Great Wall of the intestine, the intestine will remain peaceful
    .


      How do immune cells distinguish body cells and beneficial microorganisms from harmful microorganisms? Our body cells are easy to recognize because they all have the same molecules on their surfaces, just like a football team wearing the same color jersey
    .
    These molecules are very different from those on the surface of microorganisms
    .
    Granulocyte "warriors" and phagocyte "gatekeepers" can detect specific molecules on microorganisms.
    However, beneficial and harmful microorganisms have very similar molecules on the surface, so it is difficult to distinguish good from bad by these molecules.

    .
    However, some beneficial bacteria will produce other molecules to send peaceful messages to the immune system, so that the immune system can distinguish these microorganisms
    .
    These molecules are like microbes saying "Hello, friend, I'm here to help!"
    .
    There is still a lot of such secret information in the gut, and scientists are working hard to discover it
    .


      Superheroes also "play hooligans.
    "

      Sometimes, things may not go well and the intestines may be infected
    .
    Many years ago, sanitary conditions were worse than they are now, houses were not clean, and food and water often contained pathogenic microorganisms
    .
    This means that people are more likely to get sick from ingesting harmful microorganisms
    .
    Every time they get sick and recover, the immune system is better trained to fight them
    .
    Even if infected by some microorganisms that can resist this kind of resistance, such as worms, the immune system will learn how to repair the damage they cause
    .
    Therefore, in any case, people can recover from future infections more quickly
    .


      Today, however, our way of life is very different, and we have solved many of the problems of the past
    .
    We have antibiotics to kill the enemies who infect us
    .
    Our homes, food and water are cleaner, and it is unlikely that we will get sick
    .
    Together, these changes have changed our intestinal environment, intestinal flora and immune system
    .
    Now, dangerous enemies do not have as many opportunities to infect us as before
    .
    But this is also a bit "boring" for the immune system.
    Our microbial community contains fewer enemies, but there are fewer types of beneficial bacteria
    .
    When we take antibiotics, our beneficial bacteria and pathogenic bacteria are killed
    .
    Our diet has also undergone tremendous changes, which is also changing our intestinal flora
    .
    All these changes are misleading our immune system superheroes and interfering with their training
    .


      All these small changes in lifestyle combine to create "boring" and "confused" immune cells, which is not a good thing: they may start fighting, but they don’t know when to stop; sometimes they even attack the body’s own cells
    .
    The undertrained immune system superhero turns into a rogue villain
    .
    Infectious diseases have decreased, but they have led to a variety of new types of diseases, including allergies, inflammatory bowel disease, arthritis, psoriasis, diabetes, obesity, depression, cardiovascular disease and even cancer, etc.
    These are all modern society Very common disease
    .
    In fact, most of these diseases are related to changes in immune system superheroes and their intestinal training camps
    .
    These modern diseases are very complicated, because even in people with the same lifestyle, not everyone will get sick
    .
    This is because all individuals are different, not only in characteristics such as hair color or height, but also in the way cells work
    .


      The magical story that happened in the gut

      (A) Immune cells can recognize them through the peace-keeping molecules produced by beneficial bacteria
    .


      (B) If the microorganisms are friendly, General Lymphocytes can calm the soldiers down
    .


      (C) Antibiotics help kill disease-causing bacteria, but they can also kill beneficial bacteria
    .


      (D) Intestinal cells form a barrier to keep microorganisms out of the body
    .


      (E) When the barrier is broken, immune cells will lend a helping hand
    .


      (F) Unfortunately, certain aspects of modern life cause immune cells to fight against the body's own cells
    .


      Conclusion

      For us and our intestinal flora, the world is changing
    .
    But don’t worry too much, we can do many things to take care of our intestinal flora and let it continue to effectively train our immune system: bad bacteria like sweets and junk food very much, so if you can, replace sugary foods with Fruits and vegetables, fresh, natural, unprocessed, and real food will also help our beneficial bacteria grow and protect us; use antibiotics carefully, if not necessary, and resolutely do not; wash hands before meals, but do not pay too much attention to cleanliness, this Enough to avoid most infections
    .
    If we pay more attention to these things, there is no need to worry too much, we can trust our immune system superheroes
    .


      Remember, the intestine is a training camp for the immune system.
    Our diet and lifestyle affect our intestinal environment and determine whether the immune system becomes a superhero or a rogue villain
    .
    Each of us has the ability to transform the immune system into a superhero, and we also have the weakness of transforming it into a rogue villain
    .
    Maintaining a healthy intestinal training camp environment can provide a superhero to protect our physical and mental health
    .
