So, Feifei pretended to be "White Rabbit Mother", held her voice, learned the female voice, and said in a milky voice: "Little rabbit, open the door, open it quickly, I want to come in." ”

I didn't hear back when I called three times, but I seemed to hear a voice coming from the cell door: "If you don't open it, you won't open it, Dad won't come back, and no one will open it." ”

Immediately afterward, another voice sounded from inside: "The code is wrong, we must not open the door." ”

Feifei was shocked, wow! It turned out that it wasn't Mom, but Dad! Hi! Isn't that too much for me!

It's not easy to pretend to be a father, but we're authentic "manly"! Isn't that easy to do!

Thinking of this, Feifei said again in the tone of "adult male", which was naturally the voice of the male fox: "Little rabbit, open the door, open it quickly, I want to come in." ”

At this time, a voice finally came from inside the cell gate that surprised him: "The code is right." Please insert the key into the lock hole and use the key to open the door. ”

Yes! It turns out that there is another program! It seems that it is really not easy to enter this cell gate, and it is probably even more difficult than entering the bank vault door in the macro world.

It is necessary to match both the code and the key.

Fortunately, I got it right, what a fluke!

This next step is that the key is right.

The so-called "key" is at the top of the tentacles of the virus (in fact, it is called 'filiform' in medicine, and it is called 'antennae' for easy understanding), and as long as you insert it into the keyhole of the cell gate, rotate it to the left or right, and you will see if it can open the cell gate.

Who knows, 99.9% of the millions of viruses controlled by Feifei are unqualified and cannot be inserted into the lock hole and cannot open the door, but also triggers the alarm system of the cell gate, and immediately sends out a distress signal, and a large number of antibodies and white blood cells swarm from all directions when they hear the news, and launch a fierce attack on the Feifei virus that cannot enter.

Feifei knew that even if he tried desperately to resist now, it would be futile to choose to give up, and gather all his souls into about one thousandth of the virus that had already entered the cell, and only about two thousand viruses had entered the cell.

In this way, Feifei also "saw" the scene inside the cell at this time, and he was very surprised, one by one the viruses mixed into the cell were regarded as important nutrients by the cells, and were surrounded by a protein, these proteins pinched out a part of the cell membrane from the cell membrane, wrapped the virus, and then transported the nutrients they thought were deep into the cell.

Feifei felt a great contrast, the cell generally regarded all the substances outside the cell as enemies or dangerous molecules, and strictly guarded it, and it was strictly forbidden to enter it casually. And once you enter, they will treat you as if you were a guest and receive you warmly.

Just when Feifei was complacent and thought that everything was fine, unexpectedly, the virus wrapped in the cell membrane was transported to a place called "endosome sorting station".

This "sorting station for endosomes" is responsible for distinguishing the substances sent in and deciding which part of the cell to transport them to, in this process, they usually have to decompose the substances, and the inner wall of the sorting station is equipped with a special protein pump to inhale special atoms to make the inside of the endosomes acidic, and break down the large nutrients into small molecules for easy transportation and absorption.

As soon as I heard that these viruses of his were going to be broken down by the acidic proteins in the sorting station, I couldn't help but be surprised: I am afraid that these viruses that have been mixed in with great difficulty will be decomposed by these acidic substances soon, so wouldn't the huge sacrifice I made before be in vain?

Suddenly, something unexpected happened to Feifei.

Although the outer shell of the virus has been easily dissolved by these acids, the well-tested virus does not surrender so quickly, but uses this opportunity very cleverly, the dissolution of the antennae (fibroids) on the outer shell of the virus releases a protein hidden inside the virus, its function is to dissolve the inner membrane of the endosomal wall that holds the virus, the virus is not only not dissolved, but breaks out of the encirclement and successfully escapes from prison.

From this point, it can be seen that the virus controlled by Feifei knows the properties of the cell well and is definitely prepared.

However, in this process, there are also many viruses that fail to escape from jailbreak, and they are directly dissolved by acidic proteins.

Therefore, it can be said that Feifei's concern just now is not unreasonable.

At this moment, the virus is still far from success.

Viruses that don't have antennae (filibrils) roam around, and 90% of viruses stop there.

Now Feifei only has about two or three hundred viruses left, and he is still stubbornly advancing towards his final destination.

In this long arms race, though, the virus has learned a skill that allows its structure to be adsorbed to the cell's motor proteins.

Motor proteins are responsible for transporting raw materials within the cell, which are essential for chemicals and cell survival.

However, they did not expect that the material transported this time would kill them in the near future. So we completely say that the motor protein is the pig teammate of all the proteins in the cell, which is even more stupid than Zhu Bajie in "Journey to the West".

Thanks to the help of this pig teammate, the virus rides on its back, on a cytoskeleton made of proteins (like a long viaduct), along which the virus marches towards the nucleus.

So far, the virus has been invading the fox for about an hour. However, it is still an hour away from the nucleus.

At this time, the fox's body did not give up resistance, so in the next hour, the virus will not go easily.

Sure enough, along the cytoskeleton (viaduct), there is a special defense protein that searches for anything that carries antibodies, adsorbs on it, and summons proteasomes to crush the virus and recycle the protein.

At this moment, this fierce war is being staged in the cell body, and many viruses are killed by the discovery of defense proteins without paying attention......

Feifei roughly estimated that on the way to nucleus removal in the cell body, about 180 more viruses disappeared.

Normally, with the cooperation of defense proteins and proteases, the army of viruses can be wiped out in a matter of hours.

However, if even one fish slips through the net, the virus can turn defeat into victory.

Two hours after the virus invaded, the virus inevitably encountered a new problem – how to enter the nucleus.

We know that the nucleus is located in the center of the cell, the passage into the nucleus, and there are protein tentacles responsible for screening and transporting substances to the nucleus, and billions of messages and instructions pass through these channels to complete the information transfer between the cell and DNA.

Here, the role of protein tentacles is important, and it has an unshirkable responsibility to "check the pass".
