After the bewildered killer T cell woke up, he saw Feng Baobao squatting on the ground. _。 Looking at it, I couldn't help but roar: "Who are you TM!" ”

They responded with a "crackle! "A couple of slaps.

It wasn't until the killer's T-cell mouth was swollen that Feng Baobao couldn't stop his hand, and at this time, several cells buried in the soil next to him also woke up.

"Let me ask again, who is your boss?"

"My boss is a helper T cell!"

"Wrong answer!" Feng Baobao waved Okamoto 0.01 in his hand, and wiped the neck of the killer T cell, and a head flew up, and blood splashed the faces of several cells next to him.

The cells had a blank brain, obviously caught off guard by Feng Baobao's hand.

"You...... Who are you? Why did you wait for me to do this! ”

Before he finished speaking, the open cell head also flew up.

"I don't need to talk nonsense, ask what to answer. Either die. Feng Baobao said lightly.

Seeing the two dead cells, the remaining cells were cold, and they had an inexplicable fear of Feng Baobao, who was carrying a black shovel in his left hand and a knife in his right hand. It was the first time they had encountered such a ruthless person, killing people without blinking.

"We don't know anything!"

"Please, you've gone around me, you've gone around me!"

Seeing the cells that kept kowtowing and begging for mercy, Nightshade was a little unbearable: "Bao, Sister Bao'er." I think they're innocent, they don't know anything, so you can't be the wrong person, right? ”

"I wouldn't be mistaken for the scumbag smell on them." Feng Baobao pointed to the corpse on the ground and said lightly.

At this moment, the clothes on Feng Baobao's body with the cells killed by Okamoto 0.01 changed, and their skin, which was still full of activity just now, became wrinkled, like a dried corpse, and their bodies had already lost their vitality!

"This ...... Is this a virus? Nightshade opened her mouth.

"Say, who is your boss?" Feng Baobao turned his head to a few shivering killer T cells.

"Did you find out?" The cell that kept kowtowing and begging for mercy just now saw that his identity was exposed, the look of horror on his face disappeared, and his eyes looking at Feng Baobao were full of sarcasm: "Hehe, want to get information from our mouths?" Don't think about it, we won't say it when we die! ”

"Long live the boss!" After saying that, these cells with fanatical faces decisively chose to commit suicide.

At the moment of their death, the skin on their bodies became like zombies, but the frenzy on their faces remained undiminished.

"Bao, Sister Bao'er, what's going on with these immune cells? How did it become a virus? "Nightshade Road.

"I told you before. The more insidious the virus, the more it will disguise itself, and these immune cells are infected and brainwashed by the virus. They have long since lost the activity of a cell. Feng Baobao said.

She had just tied up the viruses with venom and buried them in the ground, but in their memories, there were only sporadic fragments, and there was never a shadow of the person behind the scenes.

"However, these viruses are really insidious and never show their true faces. Trying to find them is like looking for a needle in a haystack! Feng Baobao muttered.

"Sister Bao'er, what's the matter with this bacteria and virus?" Nightshade asked like a curious baby. Hot Books

"A virus is a simple individual with a simple structure containing only one nucleic acid DNA or RNA, and they must parasitize in living cells and multiply in a replication manner before they can spread and infect other organisms, and bacteria are one of the main groups of organisms and belong to the bacterial domain." Feng Baobao explained.

"What about these infected cells? They look like normal killer T cells! How did it suddenly become a virus? Nightshade wondered.

"The immune system is the body's "defense guard", which plays a role in fighting the invasion of foreign pathogens, supervising and cleaning the body's internal environment, and storing information about each defense response.

An important function of the immune system is to recognize dissent. Through this recognition, the body's own tissue cells can be protected, while actively removing foreign substances and waste from the body.

Normally, the human immune system only responds to antigens such as foreign harmful pathogens (T lymphocytes and antibodies), but does not respond to antigens in its own tissues, which is called "immune tolerance".

However, in some diseases such as rheumatoid arthritis, myasthenia gravis, systemic lupus erythematosus, etc., the immune system in the body mistakenly induces an immune response against the antigens of the own tissues and attacks and destroys the own tissues. These diseases are called autoimmune diseases.

That is, you said before that you disguised yourself, quietly lurking on the host, and kept saying to the immune system that I am good, I am good, and look, those are the bad. Feng Baobao explained.

Nightshade: "......"

"But rest assured, 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?" Nightshade laughed dryly.

"Quite the case is that trauma or infection can disrupt this immune isolation.

For example, if the left eyeball ruptures and lens material enters the bloodstream, it can 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 similar antigens, such as streptococci and normal kidney tissue, when streptococci infect the body and induce an immune response, the antibodies will mistakenly attack the similar kidney tissue antigens, resulting in rheumatoid nephritis.

Another cause is the alteration of the autoantigen caused by the chemical. For example, taking certain chemical drugs can alter the properties of red blood cells, causing the body to produce anti-red blood cell autoantibodies and destroy red blood cells, leading to anemia. Feng Baobao said.

"Before that, my brother used the body of ten thousand poisons to absorb the virus made of cold ice, as well as swallowed HIV, the Black Death, Ebola, SARS, SARS, avian flu and other susceptible viruses, does that mean that these foreign viruses will cause my brother's own immune system to attack his own tissues?" Nightshade Road.

"Hmm. It seems like so. Feng Baobao touched his chin and said.

"So, there are already a lot of viruses that change their own antigens in our cells?" Nightshade 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 anti-red blood cell autoantibodies and destroy red blood cells to cause anemia, so is the virus created by Liang Bing considered a chemical drug?"

"Count!"

"In that case, Nan Nan and Su Su are in danger, the two of them are red blood cells, and they are responsible for stopping bleeding and clotting!!" Nightshade exclaimed.

"Calm, calm, Nan Nan and Su Su are platelets, not red blood cells, red blood cells are creatures wearing red hats, their main job is to carry out the transport and exchange of oxygen, carbon dioxide and nutrients, the nature of the two is not the same at all, don't mix it up." Feng Baobao pointed to the red blood cell tract where the cart was used to transport things.

While speaking, Feng Baobao stretched out his hand to take the basket that the red blood cells carried on his arm, took out a few sandwiches, bread and other foods, and said a few words of thanks to the other party, and said to the nightshade while eating: "These foods are the nutrients they transport. ”

"Eat as much as you want, take whatever you want, you're welcome."

Nightshade: "......"
