In the second episode of the second season of "Working Cell", a new virus appears, which is called the mumps virus. In this episode, memory cells have always thought that they have the ability to foresee the future, but they don't, but they can't remember the virus. However, b cells fight viruses and need to memorize antigenic information provided by cells. In the end, it was the B cells that reminded him of everything about the mumps virus, which eventually eliminated.

Memory cells and B cells interact with cells, which are lymphocytes that are immune to memory antigens, shielding the body from secondary invasion by the same bacteria and viruses. However, the memory cell in the play is a Ma Daha, who forgets what happened before and thinks that this is the ability to foresee the future.
Antibodies form cells, which can produce weapons called antibodies, used to fight bacteria or viruses, which belong to a type of lymphocyte, but they do not have the ability to phagocytosis like white blood cells, and need to rely on the antigen information provided by memory cells to create the corresponding antigens.
In this episode, memory cells have always thought that they can foresee the future, and there is always a certain fragment in their minds. Memory cells once thought it was the end of the world and exaggerated the dangers of the mumps vaccine. In fact, this is a vaccination, the previous mumps virus has actually been inactivated, the main purpose is to make the memory cell remember its characteristics, can meet him, to provide relevant information to the B cells.
Memory cells have always wanted to open up their ability to meet the future, and it was finally the knock of the b cells that allowed him to restore this part of his memory. In fact, there is no so-called meeting the future, it is all things that have happened before, just memory cells, a little amnesia, such a situation will occur.
The body actually has the ability to be immune to the mumps virus, and this time the mumps virus is really coming. After this virus is infected, it will make the sides of the face swell and look like an Adofo mask, so mumps is also called Adofo cold. The emergence of the mumps virus in large numbers once put white blood cells in trouble, and the key was the cooperation of memory cells and B cells.
After the memory is restored, the combination of memory cells and b cells creates a large number of antigens, and finally easily eliminates the mumps virus. In fact, after vaccination, generally will not be re-infected with the corresponding virus, but the memory cell memory does not seem to be very good, so there will be such a situation.
Of course, in the end, the memory cells were beaten by many cells, but this could not all be blamed on him. After all, there are so many bacteria and viruses, there will always be times that cannot be remembered, as long as the chain is not dropped at the critical moment, everything can be made up.
