Chapter 508: The tragic immune war

The micro-video continued to demonstrate, Zheng Xuanyu said, "Ebola virus will treat healthy somatic cells as a raw material warehouse and manufacturing factory for virus processing, and continuously self-replicate. When the raw materials in healthy cells are used up, the cells lose their value. At this point, the Ebola virus will instruct the cells to synthesize a lysozyme, which will lyse the cell's cell membrane, but after the cell membrane is melted away, a large number of viruses will overflow from the enslaved cells and attack other cells. . "
Zheng Xuanyu said here, Gao Siqi added: "This is the most terrible part of the virus. It has few base pairs, but it can command and control more advanced somatic cells to serve it."
Zheng Xuanyu continued to explain with the micro video: "Is the human immune system so fragile? Of course you are not. When the infected cells emit more viruses, they will also anger the human immune system. At this time, other immune in the human body Cells, such as white blood cells, will launch a crazy attack on Ebola virus. "
"But it ’s a pity that these immune defense tools and Ebola virus are two lines. They ca n’t recognize Ebola and they ca n’t attack, just like you use Chinese to call foreigners in different Chinese, and others do n’t understand and do n’t get angry. These immune defenses are ineffective against Ebola. "
"It is not effective against Ebola virus, but it is extremely harmful to humans themselves. The proliferation of immune cells will cause healthy cells to rupture, such as ruptured red blood cells, and a large number of healthy cells will also be attacked by immune cells. This is why many people with E. Patients with Bora virus develop ecchymosis or even direct bleeding. The more healthy people, the more immune-impaired people, the more likely they are to be injured at this time. "
"This is just the first step in Ebola's attack on human health. In the second step, Ebola will capture lymphocytes, the smallest white blood cells. The main executor of almost all immune functions of the lymphatic system is to fight external infections and Frontline soldiers monitoring cell mutations in the body, and the captured lymphatic system will issue instructions to the body's immunity to stop it from making and producing immune cells. "
Zheng Xuanyu said here and sighed: "This is the most important part of the game between Ebola and the human immune system, because not all cells in the human immune cells are not Ebola's opponents. There is a kind of cell that can compete with Ebola. A Bora can even have the upper hand-natural killer cells. "
但是 "But because the lymphatic system has issued instructions to suppress the production of immune cells, many natural killer cells that are still in their young state stop growing, and mature natural killer cells have no fighting power, so they are strangled by Ebola."
Xiao Xiaoming said, "In fact, at this step, the human immune system is finished, right?"
Zheng Xuanyu said: "It can be said, but human beings still have a final counterattack-breaking the boat and sinking the water, fighting backwaters."
"The main way that the virus captures the cells of the entire human body is through the blood, and the human immune system has also become aware of this after its failure. At this time, very dangerous things have happened. In order to avoid systemic infections, the permeability of human blood vessels will increase. Such a large amount of blood will penetrate into the body through the blood vessel wall. This is a battle against water. "
Through Zheng Xuanyu's description and micro-video demonstration, Xiao Ming can realize that this is the worst battle in the history of human immunity.
This tragic situation is like the imperial palace surrounded by the country's ruined house. The emperor did not have a single soldier, but only brought his concubine and children to kill the enemy.
But this approach is undoubtedly self-defeating.
A large amount of blood enters the body through the blood vessel wall, which will cause massive bleeding in the internal organs. Edema and other irreversible pathological reactions, at this time, the patient is dying. Even if Ebola slows down the capture of whole body cells, humans will die due to the collapse of the immune system and blood circulation system.
At the end of the micro-video, dead Ebola infected people appear in the video. They are skinny, their skin ulcerated or they blister or swell.
Zheng Xuanyu concluded: "This is the terrible part of the virus. It has a simple structure but can use all the resources of the human body to serve itself. In fact, it is not just the Ebola virus. The deadliest viruses such as influenza, HIV, smallpox, etc. The place is also here. "
Xiao Xiaoming said: "This is like a computer virus, just a few simple codes can make the entire computer system serve it."
Gao Siqi talked about the maple leaf country ’s vaccine problem. "Maple leaf country vaccine research has also made some progress, but the cost is high, and there is no large-scale application. Moreover, Ebola virus has a strong evolutionary ability, its receptor glycoprotein Maybe it will change how much the vaccine is really effective, it is difficult for us to grasp.
And the vaccine can only be used before the disease, and it will have no effect after it is used, which is also a common problem of most virus vaccines. "
Xiao Ming has a sober understanding of life sciences. He described the power of the virus through the descriptions of Zheng Xuanyu and Gao Qiqi. It is very unsafe just to prevent the virus surface glycoprotein and receptor binding, because the glycoprotein on the surface of Ebola Will change with the environment and self-mutation ~ EbookFREE.me ~ What is your plan? Xiao Ming asked.
Gao Siqi was a little tired at this time, she said: "To find the core key of the virus, the virus genes must have a certain sense of the answer, their arrangement and expression will definitely tell us the answer. As long as the core key is found, Knowing that a certain type of gene can control human cells to serve it, then we are half successful. The same method can be used to overcome other viruses. This is the universal law of life.
There are also technicians from the Life Science Lab in South Africa. They will send the detailed genes of Ebola, and will also determine the gene expression mode through a series of experiments. Humans can one day defeat the virus. "
Xiao Xiaoming said: "You take a break early, and during this time you will be on vacation there, play games and visit the virtual shopping area, relax."
Zheng Xuanyu smiled sweetly at Xiao Ming and said, "You also rest early, I have to sleep, and I'm stuck."
Withdrawing from the virtual community, Xiao Ming was sitting on the sofa and lost in thought.
The core genetic material of prions, DNA and RNA, must be stable. They are the key to causing disease, while the genetic material that has evolved and mutated only changes to suit the host.
的 The only thing that can defeat the virus is the human immune system itself, which should be the starting point of life science laboratory research.
