More than 20 cells were entangled and trapped, and the macrophages began to eat slowly.
Although there are more lysosomes in macrophages than ordinary cells, they are not too many, just like how big a person's stomach is, it will not exceed the limit of the human body.
Macrophages can't swallow more than 20 source cells in one go, they can only swallow them one by one.
With each phagocytosis, macrophages are constantly collecting information about the source cells.
After the player's source cells are decomposed by the lysosomes of macrophages, a large number of source cell characteristic proteins are collected by macrophages and stored in the cells.
The more characteristic proteins of source cells collected, the greater the success rate of identifying source cells in the future.
Chapter 248 Immune Line of Defense
At this moment, the macrophage, like a scout, has captured a large group of invaders, analyzes the information of the invaders from the body of the invaders, and collects samples.
Finally, after 10 minutes, all the source cells had been phagocytized.
The macrophage is satisfied with expelling a lot of waste with vesicles. Near its nucleus, there is a small vesicle floating, which is filled with the characteristic proteins of the source cell.
After all the players died, the live video source was lost in the live broadcast room. The live video was frozen at the moment when the last player died, and the screen went dark.
The players watching the excitement chatted for a while in the live broadcast room with a black screen, and then dispersed.Everything that happened just now, in the eyes of the players, was just a thrilling adventure, and the heat quickly dissipated.
"e go never return" and others are also resurrected at the birth point, a large group of pioneer players gathered together, reminiscing about what happened just now.
Some players are also very worried, for fear that macrophages will also attack ordinary players.
However, this worry was quickly dispelled.Occasionally, players encountered macrophages in the wild, and the faction symbols on the top of the macrophages also marked the "friendly" side, and no macrophages took the initiative to attack players.
The player took it for granted that the macrophage should be a rebellious white blood cell, so if you encounter it in the future, just stay away from it.It is also a good choice to form a team to reject it.
Soon, the heat of this little episode faded away.There are too many attractive novelties in the game world, and videos that attract players' attention emerge in endlessly. The incident of macrophage attack is just a small ripple in the ocean, which is insignificant.
No one realized that a large-scale crisis was coming.
The macrophage recovered from the berserk state, and with the processed source cell characteristic protein (now it should be called antigen), hurriedly swam towards the "command headquarters" of the immune defense line.
In the tissues of the human body, in addition to densely covered with tiny capillaries, there is also a ubiquitous pipeline - lymphatic vessels.
The so-called lymphatic vessels, which are similar to capillaries in appearance, are channels for cells to swim.But specific to the function, the two are very different.
Most of the "civilian" cells that swim in the capillaries are red blood cells and platelets, which are responsible for daily delivery of nutrients and maintenance of blood vessels.
But what swims in the lymphatic vessels is the army in the cells—lymphocytes!
If capillaries are regarded as civil highways, then lymphatic vessels are military special lines.
A large number of lymphocytes live in the lymphatic vessels, gather through the movement of the lymphatic vessels, and constitute the most critical third line of defense in the human body!
After judging, the macrophages believed that the intruders this time were not trivial, the number was unknown, and they would kill red blood cells, which was extremely harmful to cell safety. Relying on phagocytes alone was no longer enough to deal with the threat.
Therefore, the destination of macrophages is a certain lymph node in the lymphatic vessel.It decides to go to the lymph nodes, asking for a third line of defense.
In the human body, there are three main lines of defense:
The first is the skin and mucous membranes, which are the outer walls of the human body;
The second is the bactericidal substances and phagocytic cells in the blood, which are the patrolling police in the cellular world.
Macrophages are a type of phagocytes and belong to the second line of defense.
Under normal circumstances, after encountering an intruder, macrophages will chase and kill the intruder as much as possible, and will not directly activate the third line of defense.
Just like when the "sensing object" was hunting red blood cells at the beginning, the macrophages only issued a wanted order for the "sensing object" in a small area, and only a dozen surrounding phagocytes were chasing and killing the source cells.
For the first time, the macrophage judges that the "sensing objects" are similar to thieves and robbers in the human world, and it is enough to hand them over to the patrolling police.
However, in the process of chasing and killing "sense objects", macrophages saw more source cells.These source cells are organized, unknown in number, and extremely threatening.
Therefore, the macrophage changes its judgment and judges the source cell as the [foreign invasion army of the cell world].
In this way, relying on patrol police alone is not enough to counteract the invading army.Macrophages need to ask to open the regular army in the third line of defense.
To request the regular army to take action, evidence of the invading army is required.
The characteristic protein of the source cell extracted by the macrophage is the evidence of the invasion of the source cell. According to the popular saying, this thing is called an antigen.
The stronger the evidence, the more likely regulars in the third line will agree to fight and the easier it will be to kill the invaders.
Once the third line of defense is activated, it will be the beginning of the all-out war. Unless all the invaders are killed, they will die forever!
Moreover, even if all the intruders are killed, the army in the third line of defense will still send special sentries to guard against the reappearance of similar intruders.
The army in the third line of defense is mainly lymphocytes.
They live in immune organs such as lymph nodes, tonsils, and bone marrow, and are natural soldiers.
The lymph nodes where they live are one of the most important immune organs in the body and spread all over the body.
Lymph nodes are the front-line headquarters of the third line of defense in the immune defense line, and it is also the place where macrophages can most easily contact lymphocytes, and the two sides often exchange information with each other here.
After swimming for almost half an hour, macrophages came to the nearest lymph node entrance.
As soon as it entered the entrance, a group of lymphocytes hurriedly brushed past it.The macrophage hurriedly stopped one of the cells and said, "I need your help urgently."
The blocked lymphocytes were in a hurry, and seemed to be in a hurry: "Why are you stopping me? I have an urgent task!"
"Aren't you a T cell? I have an antigen here that you need to deal with." The macrophage said that it was about to exocytate the antigen.
"Please take care of me. I am an effector T cell. I have already received specific tasks and I will no longer accept additional tasks. Go find undifferentiated T cells and don't delay my work!" After finishing speaking, this group of T cells Hastily left.
Seeing that the opponent did not accept the task, the macrophages had to go deep into the lymph nodes to find other T cells.
Along the way, urgently mobilized lymphocytes can be seen everywhere, and various antibodies are produced and urgently transported to the front line.A busy scene throughout the lymph nodes.
Finally, after searching for a while, the macrophage finally saw the t-cells that hadn't accepted the task, and it immediately approached and stopped one of the t-cells.
"What do you want from me?" T-cell asked.
"Yes, sir." Macrophage said, "I have found a dangerous invading army, and I request a full-scale war against them!"
Chapter 249 Humoral Immunity and Cellular Immunity
"All-out war? My God, we have enough things, and you still want to make trouble for us?" T-cells were a little reluctant, "What you phagocytes 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-cell was stunned for a moment, and took the antigen: "You wait here for a while, I will deal with the antigen, and see if we don't want us 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 the T cell.
Not long after, the T-cells hurried back and 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-cell 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.
The T-cells hurried back to the cave and began to gather their hands.
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 kinds of immune programs. In addition to humoral immunity dominated by the army of B-cells, there was also cellular immunity dominated by the army of T-cells.
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 have no nonsense, and an excellent 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 phagocytic cells 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.
"Dear colleagues, a new invader has 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-cell 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 who had received the order shouted in unison, and returned to their cave, firmly memorizing all the characteristics of the intruder, never to forget it!
About an hour later, this b cell was assigned to the memory cell army, and it was released from the lymph node, and it was about to be scattered in all corners of the body.
Lymphocytes have spent expensive resources cultivating this army of memory cells.
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.
2 Fifty Chapters Game Promotion
All three armies of lymphocytes are in action:
An army of b cells is responsible for producing antibodies in the rear;
A T-cell army is responsible for frontal combat;
The last army of b cells (memory cells) is responsible for the vigilance of the next invasion.
The memory cells act very quickly the next time an invader strikes.However, when the invader first invades, these lymphocytes are not as fast to respond.
After all, it was the first time the intruder came, and the t cells and b cells didn't know much about the intruder, so they were caught off guard.
Even if there is first-hand information provided by macrophages, the information needs to be processed.
