The medical black technology system of the top student

As the number of people participating in drug clinical trials has reached the required number, clinical trials have officially started.

A doctor responsible for following up on clinical trials opened the door and walked in and said: "Director, all patients have completed their drug injections today."

The director nodded: "How is it? Are there any side effects?"

"Not yet, everything is normal at the moment."

"Well, continue to follow up on the clinical trial data."

At the same time, some subtle changes are taking place in the lungs of lung cancer patients participating in clinical trials.

The squamous epithelial cells living in the alveoli heard a knock on the door early in the morning. He thought it was red blood cells transporting carbon dioxide and nutrients, so he opened the door without thinking.

But as the door opened, what came into view was not the familiar red blood cells of the past, but a tall, thick-looking guy with a ferocious face and a hateful appearance.

“Lung cancer cells!

The face of the squamous cell suddenly turned pale. The lung cancer cell did not talk so much nonsense with the squamous cell. He asked with a ferocious face: "Old Biden, hand over your nutrients to me!"

The squamous epithelial cells trembled and said: "We, our nutrients have been robbed by you, and we have no extra nutrients now."

"No, then you'd better not be found by me, otherwise you will suffer the same consequences!"

The lung cancer cell's expression immediately became fierce. His eyes swept across the room, and soon he found an ATP in the corner of the room.

The squamous cell's expression immediately became panicked: "No, that's the last bit of food my family has."

"Go away, you old guy who doesn't know how to live or die!"

The lung cancer cells were merciless and kicked the epithelial cells away. At the same time, he stuffed the ATP into his mouth, and the ATP was absorbed by the lung cancer cells.

The body of the lung cancer cell also gradually changed. His body began to grow rapidly. Then, under the horrified eyes of the epithelial cells, the cancer cell underwent mitosis, split into two, and became two lung cancer cells.

The two lung cancer cells sneered at the same time. They grabbed the epithelial cell and threw it out of the room.

"From today on, this alveoli belongs to Mr. Cancer and us. You can die as far away as you want. If we see you again, be careful, we will kill you directly!"

The epithelial cells looked angry: "If you do this, the immune cells will not let you go."

"Immune cells, huh."

The cancer cell seemed to have heard some joke: "You said that fool who only knows how to fight and kill all day long, we will be afraid of him, look around you!"

Epithelial Cell suddenly looked around, but when he saw the situation around him, his face suddenly turned pale.

I saw countless lung cancer cells breaking through one lung cancer after another, and a large number of epithelial cells like him were driven out by the lung cancer cells.

But what shocked the epithelial cells the most was that after the lung cancer cells occupied the living space of their epithelial cells, they quickly climbed up the alveoli.

Above the alveoli are criss-crossing tubes, in which countless red blood cells are transporting oxygen and carbon dioxide.

The cancer cells climbing up the pipes are trying to find a way to break through the pipes.

After seeing this scene, Epithelial Cell suddenly realized something, and he looked horrified and terrified.

This is transferring!

Lung cancer cells are metastasizing!

Once a blood vessel is punctured by lung cancer cells, countless lung cancer cells will swarm in and migrate along the blood vessels to the brain, liver, bone marrow and other parts of the body.

By then, even immune cells will be hard to find and unable to stop.

The epithelial cells screamed in horror: "How dare you."

The lung cancer cell sneered: "Why don't we dare."

"When our transfer is successful, the owner of this body will be ours, and we can do whatever we want then!"

The epithelial cells looked angry: "If you do this, the immune cells will not let you go."

"Immune cells, huh."

The cancer cell seemed to have heard some joke: "You said that fool who only knows how to fight and kill all day long, will we be afraid of him?"

However, the lung cancer cell had just finished speaking when a chaotic voice suddenly sounded in the distance, and a well-equipped and indifferent cell was seen walking towards this direction.

Although he is not big, he makes many cells feel huge pressure

After seeing the behemoth, Epithelial Cell's face suddenly showed a look of surprise.

It's T cells, T cells are here!

The lung cancer cell frowned slightly: "Tsk, it won't come sooner or later, but it just happens at this time."

"You cancer cells are finished, and the T cells will not let you go." The epithelial cells laughed at the lung cancer cells.

The lung cancer cell sneered: "Then you really underestimate us. Today I will show you what our cancer cells are capable of."

Immediately, the lung cancer cells shouted: "Brothers, pretend!"

As the words of the lung cancer cells fell, the lung cancer cells that were attacking the blood vessels stopped their movements one after another. They reached out and inserted their hands into their bodies, and then pulled out with force.

A clump of protein was ripped out of the body by lung cancer cells.

The epithelial cells that were originally happy suddenly looked horrified when they saw the ball of protein.

"Impossible, this is absolutely impossible, PD-L1 receptor protein, how can you have PD-L1 receptor protein."

The PD-L1 receptor protein is equivalent to a good cell certificate. With this certificate, T cells will not attack them.

The lung cancer cell sneered: "You underestimate our cancer cells. How difficult can it be to forge a document? I said, nothing can stop our cancer cells."

With that said, the lung cancer cells threw the epithelial cells aside: "Watch carefully and see how I play with this fool."

After saying that, the lung cancer cell quickly stepped forward, and he came to the T cell.

The T cell's eyes glanced at the lung cancer cells coldly, and then said coldly: "Please show me the ligand!"

The fierce face of the lung cancer cell also forced a flattering smile: "Master T, this is my ligand certificate. Please check it. I am a big good cell."

As the lung cancer cells spoke, they stuffed the PD-L1 receptor protein taken out of their own bodies into the immune checkpoints on the surface of the T cells.

For this set of operations, lung cancer cells are very skilled, because they have done this in the past.

As long as the PD-L1 receptor protein is inserted into the immune checkpoint, T cells will think that they are harmless and good cells and will not do anything to them.

With this trick, lung cancer cells have escaped the killing of immune cells countless times.

Just when the lung cancer cells think that this time they will be like before and can easily escape the killing of T cells.

But soon, the smile on the face of the lung cancer cell suddenly froze.

Because he found that no matter how he inserted it today, the PD-L1 receptor protein could not be inserted.
