When the human body is infected with viruses through body fluids, droplets and direct contact, after the incubation period, these viruses will proliferate and kill cells in the body. white blood cells to kill these viruses.
When the number of viruses is too large, a type of leukocyte with strong killing will start to attack indiscriminately, and the larger mononuclear leukocytes will directly phagocytose the virus and infected cells.
Next, macrophages and dendritic cells will join the fight, and the immune response will leave a large number of dead cells and tissue fluid left behind.
At this time, our body starts to sneeze or cough, and produces discomfort such as fever and fatigue, which is a signal from the body to let us rest.
Under normal circumstances, when we take medicine, the virus will decrease, and our body will gradually start to improve. However, when encountering a cunning and difficult virus, the physical condition will continue to deteriorate, and the immune cells will continue to kill normal cells in large numbers.
At this time, it is difficult for the cells in the body to maintain normal work, and extreme deterioration begins. At this time, special drugs and surgical treatment must be passed to assist the immune system and reduce the complications caused by decreased immunity.
After fighting the virus for a period of time, the dendritic cells will remember the virus’s information and tell the lymph nodes that the powerful T cells in the lymph will divide rapidly and head to the battlefield, and the infected cells will also self-destruct to suppress the virus.
Then some T cells will remember all the information of the virus and transmit it to B cells, and B cells will start to produce immunoglobulins (antibodies) to deal with these viruses.
When a new virus or virus mutation appears, the difficulty we face is that no one has produced antibodies to the virus we encountered for the first time, and the vaccines that artificially induce antibodies are too late.
However, the job of making antibodies is the job of “acquired immunity” in the immune system. The immune system, on the other hand, has “natural immunity” to fight foreign bodies, with or without antibodies.
Novel is new to “acquired immunity”, neither new nor old to “natural immunity”. That is to say, people whose natural immunity is active can recover quickly even if they are infected with a new virus.
Signals of LPS-induced antiviral effects
As a substance that activates natural immunity, LPS can activate natural immune active cells – macrophages. Macrophages eat virus-infected cells for processing. LPS can activate signals that induce antiviral factors (interferon beta, etc.) (*1). Therefore, eating more LPS-containing foods on a daily basis can prevent the new coronavirus and speed up recovery even if infected.
