These days, when you're worried about your immune system, are you taking 'this'?
Role of NK Cells
Hello. I'm a pharmacist Jinny.
Every cell in our body has a unique ID card, just like humans.
It's the cell's national ID card, an identifier called MHC. Therefore, normal cells and abnormal cells have different identifiers. NK cells are very important immune cells in the human body that identify and kill these abnormal cells.
The correct name is Natural Killer Cells. These cells find only infected cells, stick to the surface of the cells, and kill the cells.
Role of NK Cells
When a cell becomes infected, the DNA in the cell is altered and thus loses its proper function.
Cells with altered DNA become vulnerable to pathogens and synthesize the DNA that produces them. When that happens, these infected cells turn into factories that continue to produce germs.
That's why NK cells are so important. NK cells circulate throughout the body and induce apoptosis by finding only infected cells. It attaches itself to abnormal cells and injects water and salt into them, disrupting the balance of the cells and causing cell necrosis.
NK cells are a kind of immune police force.
It detects virus-infected cells and tumor cells, and injects water and salt through the cell membrane to induce apoptosis.
What's even more surprising is that research has been published that NK cells attack cancer cells and prevent cancer cell development, proliferation, and metastasis. NK cells inhibit tumor initiating cells, which are the stage before cancer cells differentiate.
The usefulness of NK cells has been proven through various studies. Therefore, research efforts to increase the activity of NK cells or the number of NK cells in the body are gaining momentum.
Recently, as the number of hospitals that can test NK cell activity in the body has increased, activity tests are being actively conducted mainly for patients with various cancers and adult diseases.
This is a brief overview of the function of NK cells, which are immune police officers living in our body.
I hope you have a healthy day in body and mind. It was Jinny.
