One article understands why we need to freeze our immune cells?

human immune system

There are many pathogenic factors in the environment we live in, such as various bacteria and viruses, which want to invade the human body every moment. But don't worry too much, because each of us has a strong immune system to protect us.

What is the immune system?

We often hear the word immunity in our lives. It is actually a vague understanding of our immune system - the stronger the immunity, the less likely it is to get sick; the stronger our immune system, the more likely we are to get sick. the lower the probability.

So what exactly does the immune system do?

The main function of the immune system is to identify and remove pathogenic factors.

On the one hand, it removes external invading factors, such as foreign bacteria and viruses, and on the other hand, it removes internal threats in our body, such as cells that are harmful to the human body due to mutations caused by various factors.

A strong immune system is mainly maintained by immune organs and immune cells. Our immune organs are where immune cells are produced. Immune cells are simply called white blood cells. Our immune cells will constantly patrol the human body with the blood to remove various pathogenic microorganisms that are harmful to the human body and ensure the health of the human body.

At a young age, we have the largest variety of immune cells and can deal with a wide variety of diseases. If each disease is likened to a lock, we have a variety of keys that can be paired to open the lock, so the problem can be solved.

But as we age, our immune organs will continue to shrink, unable to produce enough new immune cells, and the types of cells will become less and less. When there are more and more cells with different mutations, our immune system can't target such diseases. Diseases will occur, the most important of which is cancer; on the other hand, if we cannot effectively remove senescent cells, the accumulation of senescent cells can also lead to cardiovascular disease.

Why are there more and more cancer patients?

Because the incidence of cancer continues to increase with age.

With the increase of age, the increase in the number of cell divisions makes more and more cancer cells, which increases the probability of cancer. With the increase of age, some cells will become senescent cells when it is time to be cleared but there are not enough immune cells to clear them. Inducing the occurrence of diseases, the occurrence of cardiovascular diseases is closely related to senescent cells.

What is the relationship between immunity and aging?

With the increase of age, the aging of the human body is inevitable. With aging comes a series of complex physiological changes in the human body - among which, immune aging and human aging are closely related.

On the one hand, immune cells clear senescent cells, but on the other hand, with the occurrence of aging, the immune system will also face decline. A recent study in the journal "Nature" confirmed that immune aging also promotes the aging of non-immune organs throughout the body, proving that immune aging is closely related to human aging.

In this study, it was also confirmed that if the cells were injected back into the mice when they were young, the aging situation could be reversed to a certain extent. If we can delay immune aging, perhaps we can delay the arrival of systemic aging.

We all know that immune cells have their own characteristics, and one of their functions is to identify others. Therefore, when non-autoimmune cells are found, they will launch an attack, which is also a problem that often occurs in organ transplantation, which is the "immune rejection" reaction that everyone often hears. At present, in order to avoid this situation, the general immune cell therapy is to select the patient's own immune cells.

So is there a way to prevent the immune cells from aging when they are aging? This requires mentioning our latest technology - immune cell cryopreservation.

The role of cell cryopreservation

Immune cell cryopreservation is a technology that extracts blood from the human body, then separates immune cells from the blood, and then uses ultra-low temperature to achieve long-term preservation of immune cells.

At present, most immune cells are cryopreserved in liquid nitrogen, and immune cells can be cryopreserved at -196 degrees Celsius for more than 20 years. And the cryopreserved cells can still maintain their original role after awakening, so as to maintain the vitality of youth

So what can immune cell cryopreservation do?

01Anti-aging

When we age, our immune cells are sent back to the human body, so that these cells that are still alive can help remove senescent cells, slow down the speed of our aging, and have a cosmetic effect.

02Fighting Cancer

The occurrence and development of cancer is a long-term process. Before that, our cells will mutate. When we send immune cells back to the human body, the immune cells can remove these mutated cells and reduce the probability of our cancer.

If we unfortunately suffer from cancer in the future, we can also reawaken the cryopreserved cells to help us fight cancer better by massively expanding and modifying immune cells. Moreover, the most cutting-edge technology in the field of cancer treatment is immunotherapy, which is currently considered to be the most promising way to overcome cancer.
