Chapter 259 Immune Disease
After the bewildered killer T-cell woke up, he saw Feng Baobao (._.) squatting on the ground looking at it, and couldn't help shouting: "Who the hell are you!"
What responded to them was "cracking!" Several slaps.
Feng Baobao didn't stop until the mouth of the killer T cell was swollen. At this time, several cells buried in the soil next to him also woke up.
"I'll ask again, who is your boss?"
"My boss is a helper T cell!"
"Wrong answer!" Feng Baobao waved the Okamoto zero point zero one in his hand, and wiped the neck of the killer T cell, a head flew up, and the blood spattered the faces of several cells next to it.
The brains of the cells went blank, apparently caught off guard by Feng Baobao's move.
"You... who are you? Why did you wait for me to do this to me!"
Before he finished speaking, the open cell head also flew up.
"I don't need to talk nonsense, just answer whatever you ask. Or die." Feng Baobao said flatly.
Seeing the two dead cells, the rest of the cells shuddered, and felt inexplicable fear of Feng Baobao, who was carrying a black shovel in his left hand and a knife in his right.It was the first time for them to meet such a vicious person, killing people without blinking an eye.
"We don't know anything!"
"Please get around me, get around me!"
Seeing the cells that kept kowtowing and begging for mercy, Solanum nigrum couldn't bear it: "Bao, Sister Bao'er. I think they are innocent. They don't know anything. Are you admitting the wrong person?"
"I won't admit the human scum smell on them." Feng Baobao pointed to the corpse on the ground and said lightly.
At this moment, the clothes on the cells that Feng Baobao killed with Okamoto [-] changed. Their skin, which was full of vitality just now, became wrinkled, like a mummy, and their bodies had already lost their vitality!
"This... is this a virus?" Solanum nigrum opened its mouth.
"Tell me, who is your boss?" Feng Baobao turned his head and said to several trembling killer T cells.
"Have you been discovered?" Seeing that his identity had been exposed, the cell that had kept kowtowing and begging for mercy just now disappeared, and looked at Feng Baobao with sarcasm in his eyes: "Hehe, I want to get information from us ? Don't think about it, we won't say it even if we die!"
"Long live the boss!" After finishing speaking, these fanatical cells decisively chose to commit suicide.
The moment they died, the skin on their bodies became like zombies, but the fanaticism on their faces remained undiminished.
"Bao, Sister Bao'er, what happened to these immune cells? How did they become viruses?" Solanum nigrumi said.
"I told you before. The more insidious the virus, the more it will disguise itself, and these immune cells have been infected and brainwashed by the virus. They have already lost the activity of a cell." Feng Baobao said.
She tied up these viruses with venom just now and buried them underground, but in their memory, there are only sporadic fragments, and there is still no shadow of the person behind the scenes.
"However, these viruses are really insidious, and they never show their true colors to others. Trying to find them is tantamount to finding a needle in a haystack!" Feng Baobao murmured.
"Sister Bao'er, what's the matter with these bacteria and viruses?" Solanum nigrum asked like a curious baby.
"Viruses are individuals with a simple structure that only contains one nucleic acid, DNA or RNA. They must parasitize and multiply in a living cell in order to spread and infect organisms among other organisms. Bacteria are the main group of organisms. One of them belongs to the bacterial domain." Feng Baobao explained.
"Then what's the matter with these infected cells? They look similar to normal killer T cells! Why did they suddenly become viruses?" Solanum solanum wondered.
"The immune system is the "defense guard" of the human body, which plays a role in resisting the invasion of foreign pathogens, supervising and cleaning the internal environment of the human body, and storing information about each defense response.
An important function of the immune system is to recognize aliens.Through this recognition, the body's own tissue cells can be protected while actively removing foreign substances and garbage in the body.
Under normal circumstances, the human immune system only produces immune responses (T lymphocytes and antibodies) to foreign harmful pathogens and other antigens, but does not respond to self-organized antigens, which is called "immune tolerance".
However, in patients with some diseases such as rheumatoid arthritis, myasthenia gravis, and systemic lupus erythematosus, the immune system in the body mistakenly induces an immune response against self-tissue antigens and attacks and destroys self-tissues.These diseases are called autoimmune diseases.
That is what you said before, disguising yourself, lurking quietly on the host, and constantly telling the immune system that I am good, I am good, look, those are the bad ones. "Feng Baobao explained.
Solanum nigrum:"……"
"But don't worry, the human brain, lens and other tissues are special parts that the immune system cannot enter under normal circumstances, and will not cause an immune response. So the small oysters are still safe." Feng Baobao comforted.
"What about the unusual situation?" Solanum nigrum asked with a dry smile.
"Unusually, things like trauma or infection can disrupt this immune isolation.
For example, if the eyeball of the left eye ruptures and the lens material enters the blood, it may encounter immune cells in the blood, induce an immune response against the lens, and then attack the normal right eye, resulting in sympathetic ophthalmia.
Another reason is that similar antigens, such as streptococcus and normal kidney tissue, have similar antigenicity. When streptococcus infects the human body and induces an immune response, antibodies will mistakenly attack similar kidney tissue antigens, leading to rheumatoid nephritis.
Another reason is changes in self-antigens caused by chemicals.For example, taking certain chemical drugs may change the properties of red blood cells, causing the body to produce autoantibodies against red blood cells and destroying red blood cells, resulting in anemia. "Feng Baobao said.
"Back then, my brother absorbed the virus made by cold ice with the body of ten thousand poisons, and swallowed HIV, Black Death, Ebola, SARS, SARS, bird flu and other susceptible viruses. Does that mean that these Will the foreign virus cause my brother's own immune system to attack his own tissues?" Solanum Kui said.
"Hmm. It seems to be the case." Feng Baobao stroked his chin and said.
"So, these our cells are already mixed with a lot of viruses that change their own antigens?" Solanum nigrum exclaimed.
"Yes." Feng Baobao nodded.
"Then you just said that taking certain chemical drugs may change the properties of red blood cells, causing the body to produce autoantibodies against red blood cells and destroying red blood cells, resulting in anemia. Is the virus made by cold ice considered a chemical drug?"
"Calculate!"
"Then, Nannie and Susu are in danger. They are red blood cells, which are responsible for hemostasis and coagulation!!" Solanum nigrum exclaimed.
"Calm down, calm down, Nannan and Susu are platelets, not red blood cells. Red blood cells are organisms wearing red hats. Their main job is to transport and exchange oxygen, carbon dioxide and nutrients. The properties of the two are fundamentally different, so don't mix them up." Let's talk." Feng Baobao pointed to the red blood cells that were transporting things with a trolley.
While talking, Feng Baobao reached out to take the baskets carried by the red blood cells on his arms, took out some sandwiches, bread and other food, thanked the other party a few times, and said to Solanum nigrum while eating: "These foods are the ones they transported. nutrients."
"Eat what you want, take whatever you want, you're welcome."
Solanum nigrum:"……"
