My Cell Game

"Total war? My God, we have enough things, and you still want to make trouble for us?" T cells were a little reluctant, "What you phagocytic cells can do, don't find us."

"Sir, they have probably broken through our second line of defense." The macrophage said, spit out the vesicles in the body, and handed them over to the T cells. "This is the antigen I collected."

Seeing the antigen, the T cells were stunned for a moment, and took over the antigen: "Wait here for a while, I will deal with the antigen, and see if we don't want to take action."

After the T cell finished speaking, it left with the antigen presented by the macrophage.

What the macrophage should do has been done, it has nothing to do now, it can only wait in place according to the requirements of T cells.

Not long after, the T cells came back in a hurry, and immediately asked, "Are you sure these cells hunted down our red blood cells?"

"Yes, sir." Macrophage said affirmatively: "And more than one has been hunted down. In the area under my jurisdiction, they have been listed as the most dangerous wanted criminals."

"Damn it! I've never seen this kind of protein! We haven't seen the protein on the surface of their cell membrane, and they haven't been reported here. They don't belong to our world at all!" T cells said:

"They are an organized invasion army, and we will leave the rest to us. We will organize a special army and launch a full-scale war against them!"

After getting an affirmative answer, the macrophage left satisfied and returned to its defense zone.

Soon, the entire lymph node fell into a panic again.

T-cells scurry back into the cave and begin to muster their men.

The entrance of the cave where it lives has been hung with a new sign.

This new logo means that the T cells inside have accepted a specific task, from lymphatic T cells waiting to accept the task, to differentiated into effector T cells that specialize in dealing with certain invaders.

At the same time, antigens presented by macrophages are reprocessed by T cells.

Due to the rush of time and insufficient technology, the antigens extracted by macrophages are very rough. Except for specialized T cells, other lymphocytes are difficult to understand.

Now T cells have to reprocess antigens into a language that all lymphocytes can understand.

A few minutes later, a large number of B cells that received the order rushed outside the cave to stand by, and the T cells inside swam out with the optimized antigen.

T cells deliver lymphokines containing information about the invader to all B cells present, saying:

"Colleagues, new invaders have emerged, and I need you to arm yourself immediately.

The antibody factory needs to start a new production line, fast! let's move! According to the lymphatic factors I gave you, design antibodies that can deal with them as quickly as possible! Phagocytes on the front line need our support!

Now, I command, the humoral immunity program starts! "

With a sound of orders, the B cells that had obtained the lymphokines swarmed towards the antibody factory in the rear, and immediately began to develop the corresponding antibodies.

The T cells at the entrance of the cave did not leave. The third line of defense was mainly supported by two immune programs. In addition to the humoral immunity dominated by the B cell army, there was also the cellular immunity dominated by the T cell army.

Soon, a group of reserve T cells assembled, waiting for instructions.

"My colleagues, new invaders have appeared, and I need you to arm yourself immediately!

Here is all the information about the intruders, take them and train immediately against the intruder's weaknesses. You need to train an army capable of defeating the invaders in the shortest possible time!

Now, I order, the cellular immune program starts! "

Silent T cells are no nonsense, and a good army is often silent.

They received the intruder's information, rushed to the training ground, and trained themselves into a lymphatic army specially targeting the intruder.

The third line of defense is fully activated——

The B cells of humoral immunity are the workers on the rear production line. They produce specific weapons against invaders, carry the weapons to the front line, and assist the front-line army in combat;

The T cells of cellular immunity are the regular army fighting on the front line. They will assist the phagocytes to fight on the front line together and confront the invaders head-on.

After arranging these, the commanding T cells in the cave did not rest, and it secretly summoned a group of B cells and assigned them secret tasks.

"My colleagues, new invaders have appeared, and I need your help." This is the third time T cells have said this.

"Yes! Sir! Let's produce antibodies immediately!" The B cells were gearing up and eager to try.

"No, you have more important tasks to complete." T cells said:

"Trust our colleagues, they will kill all the invaders soon. It is only a matter of time before the invaders are eliminated. We have enough manpower, and you don't need to worry about this.

However, you should have heard that the invaders are a bunch of the most cunning and evil bastards! Even if we kill them all this time, one day in the future, they may come back again!

Some intruders, once is enough!

Now, I order you, memorize all the characteristic information of the intruder.

You will be assigned to the memory cell unit, scattered to every corner of the cell world, patrolling and monitoring all the time.

Once the same intruders invade again, you don't have to report to me, you have the highest decision-making power, deploy troops nearby, and kill them in the bud! "

"Understood!" The group of B cells that received the order shouted in unison, returned to their cave, and firmly remembered all the characteristics of the intruder, never forgetting it!

About an hour later, this army of B cells has entered the army of memory cells and is about to disperse in all corners of the body from the lymph nodes.

Lymphocytes cultivated this army of memory cells at an expensive cost.

The role of this army of memory cells is to prevent the same invaders from invading again.

Although in this all-out war, these memory cells are useless, they will neither kill the enemy front nor produce weapons in the rear, but the memory cell army is still an extremely important lymphatic army.

If you use an idiom, the memory cell force is called "planning for a rainy day".

Once the same intruder invades again, the memory cells scattered all over the place will mobilize troops as quickly as possible, they will produce antibodies by themselves, organize their own army, and wipe out the intruder in the bud.

Some diseases, such as smallpox, will never suffer again after being cured, which is the credit of this group of memory cells.

The vaccines injected in the hospital are also to stimulate lymphocytes to produce specialized memory cell troops to achieve the effect of disease prevention.
