1. Immunity that has been present since birth (Innate immunity)

It is immune to Not specific, not memorized, but there will be work on every foreign thing that enters our body. In the physical aspect, such as the skin, intestinal wall, various mucosa, including saliva, gastric juice, or various secretions. Secretion of inflammatory substances that include pain, swelling, redness, heat, and certain types of immune cells, such as Macrophage, Neutrophil and NK Cell

2. immunity that comes later

It is an immune system that has specificity must be remembered There is learning. for white blood cells The main role for this type of immunity is Lymphocyte (lymphocyte) by working must remember and learn. To respond quickly to infection or foreign objects When we meet next time Our body has applied knowledge in the matter of vaccines. which is like an injection To stimulate white blood cells to become soldiers, to remember and learn to work. And then respond more efficiently.

NK Cells are created from the same type of bone marrow that creates lymphocytes, but their shape and function are different. NK Cells are large and have no specificity in their work. There is no protein coating on the cell surface. The work of NK Cell focuses on killing foreign cells, especially cancer cells. or a lump that has abnormal growth Including virus cells hidden in our body. Because normally there are 2,000 to 5,000 million NK Cells in our body. 

Many people probably suspect that Having a high amount of NK Cells is better, right? But in fact, there are many studies that have found that It is the efficiency of NK Cells that indicates their quality in killing foreign substances in the body. Therefore, in addition to the general physical examination in terms of blood cells Checking the quantity and efficiency of NK Cell or NK Activity It will help us evaluate the quality of our body's immune system.

There are many types of examinations. By checking in a way that is similar to Gold Standard or standard examination is Bringing cancer cells Come dyed with calcein fluorescent dye. Then it was raised with NK cells to see their performance. Killing cancer cells using Natural Cytotoxicity This is a Dim type efficiency test that is over 90 percent for NK Cells in our body. Another type of test is Main examination of substances Interferon (Interferon), which is a Bright type of NK Cell. 

• lifestyle or behavior in life, we foundGroup of people who eat vegetables every dayCompared to people who eat vegetables 1 time per week. It was found that the performance of NK Cells was clearly higher than those who performed it once per week. And it is clearly seen in the group of women more than men. In addition, additional studies have found that eating meat which should be meat from grass-fed animals and soy milk products on a daily basis It will be able to increase the performance of NK Cell. Here the doctor would like to add that Choosing healthy products or choosing food should be organic or non-toxic.

• People who are overweight It also affects the work of NK Cell. Research has found that When body weight decreases, it will be seen that the work of NK Cell by all 4 mechanisms works better. Whether it's a matter of NK Cell production, secretion of inflammatory substances In order to make the efficiency of the immune response better destruction of foreign cells Or that cancer cells work better?

• smoking Found to cause NK Activity or efficiency to decrease. From the study it was found that Smoking more than 500 cigarettes per year will reduce the amount of NK Activity. In addition, it was found that Drinking only a small amount of alcohol, less than 1000 ML per year, will increase NK Activity. But if you drink alcohol together with smoking It was found to cause NK Activity or efficiency to decrease significantly.

• Fasting for a period of time or doing IF (Intermittent Fasting) Helps stimulate the work of NK Cells. โดยการศึกษาวิจัยพบว่า เวลาที่เราทำ IF หรือ  Intermittent Fasting จนจะทำให้ร่างกายเกิดกระบวนการนึงที่มีชื่อเรียกว่า Autophagy or the eating of one's own cells. The process of Autophagy will stimulate the immune system. To work and eat foreign things Or that it resists infection, especially viruses. Whether it is promoting the work of NK Cell or T-Cell, the Autophagy process will be stimulated. and promote the efficiency of the immune system in our body

• exercise It is a factor that promotes the performance of NK Cell. From research studies it is found that Exercise that improves circulation also increases the amount of NK. Cell In addition, it also increases the amount of T-Cell and B-Cell white blood cells for exercise in appropriate conditions. or moderate exercise It will reduce the inflammatory process in the body. and increases the work of NK Cell both efficiency Moderate exercise is Exercise that causes your heart rate to be 64 to 67% of maximum. If calculated according to the formula, it is 220 minus age or measured as RPE at the level of 12-13 or if you want to measure it easily. That is, during exercise we can speak but cannot sing. For exercise, there are many forms such as running, treadmill walking, and circuit training. Or you can swim.

At present, various technologies are being introduced. To help in increasing the efficiency and quantity of NK Cell is to bring in the patient's own immune cells. To be grown in a laboratory to increase quantity and quality. Then it is injected back into the patient. which this treatment

It is widely done. Whether it's in Japan, the United States, as well as in Thailand itself.
