On the 9th broadcast of KBS1’s’Secret of a Lifeless Soldier’,’There is no immunity, the truth of immunity’, we look at the scientific truth about immunity that can solve the misunderstanding of immunity.
Scientists who specialize in immunity say you should pay attention to the expression immunity. Immunity is a defense system of the human body that distinguishes between being’I’ and’not me’ and protecting me from beings that are not me, especially those who cause illness.
We often view it as being able to raise and lower immunity. And in the name of immunity, I want to increase immunity. However, excessive immune reactions can even ruin my body. Above all, as the expression of immunity, immunity is not any energy or energy. This is why scientific and clear understanding of immunity is needed more as the interest in immunity is high.
Park Eun-young (29) reported that her white blood cell count was lower than before in the recent health checkup results. These days, a lot of interest in immunity, Park Eun-young, who was worried, visited the hospital again. But the answer he heard is’no problem’. Even if the level of white blood cells, which is an immune cell that fights pathogens, drops a little, it is not a situation of concern. This is because normal is only a kind of reference value, and there is no big problem with the ratio of various immune cells that make up white blood cells. In order to solve the misunderstanding of immunity, the production team examines the various immune cells of our body called white blood cells in detail, and also takes a closer look at the two immune responses of the human body, which are the most basic to understanding the immune system, innate and acquired immunity.
Acquired immunodeficiency syndrome, commonly known as AIDS, is a terrifying disease caused by a virus that targets only the most important immune cells in the human body. When infected with HIV (Human Immunodeficiency Virus), Helper T cells, which act as commanders of immune cells in the battle against pathogens, are destroyed, destroying the body’s immune system. HIV-infected people become bodies that can die even if they catch a cold. AIDS, a fatal disease caused by the collapse of the immune system! Through the case of young AIDS patients, the onset and treatment of AIDS and the importance of the immune system are examined.
Immunity does not only attack outside invaders. They also attack our normal tissues and cells. So, it may be a mistake to think that the stronger the immunity is, the better. The case can be known through diseases related to the liver, one of the organs responsible for the central immune function of the human body.
The liver, through which numerous foreign substances pass, does not attack all foreign invaders. It helps the human body by providing’immune tolerance’ for foreign substances essential for survival, such as food. However, there are cases in which the immune response to external intruders becomes excessive or the target of attack is wrong, so that I attack myself. We look at the scientific truth about the immune response through cases of hepatitis C and autoimmune chronic liver disease. While many people often think that strong immunity is required, it is important to be aware that excessive immune responses can cause serious illness.
The immune response is likened to a two-arm scale. This is because when the balance of immunity is broken and an excessive immune response occurs, the immune balance is tilted to one side and a problem occurs. A typical example is ulcerative colitis, an immune disease that occurs in the intestine, an important organ of immunity. Ulcerative colitis is a disease in which chronic inflammation of the mucous membrane of the large intestine is caused by excessive immune responses of immune cells. With ulcerative colitis, thin stools containing blood and mucus appear several times a day. Because of the uncontrollable urgent stools, patients with ulcerative colitis have difficulty even in their daily life. The recently developed treatment for ulcerative colitis is a treatment that helps balance the inclined immune balance by selectively blocking the excessive activation of immune cells, thereby controlling the number and activity of immune cells. Through the cause and treatment of ulcerative colitis, the adequacy and homeostasis of immunity is examined in detail.
‘The Secret of the Living Soldier’ is broadcast every Wednesday at 10 pm.
