“Immunity” is one of the defense systems to keep our health. The immune system works to protect the body from external enemies such as pathogens (bacteria and viruses). The immune system is basically divided into two types: innate immunity and acquired immunity. “Innate immunity” reacts quickly to pathogens that have invaded the body, such as macrophage cells and natural killer (NK) cells. NK cells start attacking when they recognize invading pathogens. Macrophages prey on recognized pathogens and break them apart, and at the same time, when innate immunity alone cannot deal with them, inform them of acquired pathogens for help.
Role of immune system to avoid risk of infection & cancer:
The immune system plays an important role in maintaining health, but its function declines with age. The graph shows the relationship between age and immune function, infectious disease and cancer risk. Immune function peaks in the 20’s and 30’s and thereafter declines with age. On the other hand, the risk of infection and cancer rises when immune function declines. In other words, reduced immune function increases the risk of pathogen invasion and carcinogenesis. Maintaining a high level of immune function is very important to staying healthy. Recently, there are lactic acid bacteria and mushrooms (β-glucan) as food materials that enhance immune function, but in fact, Asaigermanium has been studied as a material related to immunity from many years ago. Here, are some of the research conducted by Asaigermanium Research Institute.
Asaigermanium induces interferon-γ:
Experiment ① Interferon-γ production inducing effect:
Interferons, especially interferon-γ, are important substances that activate innate immunity such as macrophages and NK cells. The effect of Asaigermanium on interferon-γ induction was addressed relatively early in immunity studies.
Test: Twelve healthy people of various ages consumed Asaigermanium and examined the changes in the amount of interferon in their blood.
Result: Despite individual differences, interferon titers rose for all, regardless of age and gender, and peaked around 30 hours later.
Activation of innate immunity (NK cells):
Experiment ② Asaigermanium activates NK cells:
NK cells are an abbreviation for “natural killer cells” and literally means “born killer.” When they recognize invading pathogens or abnormal cells, they start attacking quickly.
Test: Nine healthy people were divided into three groups of three, and each subject received 25, 50, and 100 mg / kg of Asaigermanium, and the NK cell activity of peripheral blood lymphocytes was measured.
Result: All groups showed that NK cell activity increased one day after ingestion of Asaigermanium, and that activity was maintained for four days thereafter.
Activation of innate immunity (macrophage):
Experiment ③ Spleen NK cell activity and intraperitoneal macrophage activation in mice:
Macrophages play a role in recognizing invaders such as bacteria that have invaded the body, prey on them and decompose them, and at the same time transmit information on the invading pathogen to acquired immunity.
Test: Mice were orally administered 300 mg / kg of Asaigermanium and examined for changes in spleen NK cell activity and intraperitoneal macrophage activity.
Result: 24 hours after administration of Asaigermanium, NK activity in the spleen was confirmed to have a unimodal potentiating effect. In addition, the activity of intraperitoneal macrophages peaked at 48 hours, 24 hours after NK activity. In this experiment, the number of macrophages in the abdominal cavity did not increase, so it is considered that macrophages were activated by interferon induced by intake of Asaigermanium.
Immunity and Asaigermanium:
Introducing a study that intake of Asaigermanium induces interferon-γ production and activates innate immunity, NK cells and macrophages, is only a small part of the immune system as a whole. As shown in the illustration at the beginning, there are a wide variety of cells involved in immunity. Research into the complex and systematic immune system and its relationship to Asaigermanium is ongoing.
