What does cell therapy involve?

Cell**, the full name is cellular immunity****, has developed into the fourth tumor ** after surgery, chemotherapy and radiotherapy. Its principle is to collect human autoimmune cells, after in vitro culture, so that their number increases thousands of times, the targeted killing function is enhanced, and then infused back into the human body to kill pathogens, cancer cells, and mutated cells in blood and tissues, break immune tolerance, activate and enhance the body's immunity, and take into account the dual effects of ** and health care. Including cytokine-induced killer cells (CIK)**, dendritic cells (DC)**, API biological immunity**, DC+CIK cells**, natural killer cells (NK)**, delta T cells**, etc.

Immune cells have a certain effect on cancer, which is an adjuvant way for cancer, and patients can apply it under the guidance of a doctor.

Immune cells, also known as biological immunity, are based on the principle of proliferating and activating autologous cells in vitro, and then transducing them into the body to induce their own immune response, thereby killing tumor cells, which has a certain effect on cancer and can prolong the survival of cancer patients to a certain extent.

In addition to this method, cancer patients who meet the indications for surgery should undergo surgical resection in the early stage, and those who are not suitable for surgery should be further examined by MF, CT, PET-CT and other examinations to clarify the general condition, followed by radiotherapy or chemotherapy.

Compared with the traditional ones, the effect of biological cell immunity is as follows: 1. It greatly activates the body's immune function, has strong carcidal power, has a wide tumor killing spectrum (including residual cancer stem cells and other non-proliferative tumor cells), effectively reduces the metastasis of tumors, and improves the rate of tumors; 2. It is effective for a variety of tumors (including tumors that are not suitable for surgery, radiotherapy insensitive and chemotherapy-resistant); 3. Selectively target and kill tumor cells, with no toxic effect on normal cells; Combined with the three major **, enhance the success rate of surgery and improve the efficacy of radiotherapy and chemotherapy; 4. It can avoid the toxicity and immune function decline caused by the three major diseases, significantly improve the clinical symptoms of patients, improve the quality of life, and prolong the survival time.

1.Somatic cells are a way to infuse the patient's cells back into the patient after various treatments outside the body. At present, somatic cells** are mainly autologous somatic cells**, which are divided into two categories: active specific immunity** and passive immunity**.

2.Stem cell transplantation is the transplantation of healthy stem cells into the patient's body to repair or replace damaged cells or tissues, so as to achieve the purpose of **. Stem cell transplantation has a wide range of diseases, including neurological diseases, immune system diseases, and other medical and surgical diseases.

Stem cells are known as "universal cells" in the medical community, and they can differentiate into a variety of functional cells or tissues and organs. Because the stem cells cultivated in the APSC pluripotent cell laboratory have "unlimited" proliferation and multi-directional differentiation potential, they have the characteristics of hematopoietic support, immune regulation and self-replication. There are many diseases associated with stem cell transplantation**, and the younger you are, the more significant the improvement.

The following are the diseases that can be **:

1. Stem cell transplantation**Nervous system diseases such as: cerebral palsy, spinal cord injury, motor neuron disease, Parkinson's disease, cerebral hemorrhage, sequelae of cerebral infarction, sequelae of traumatic brain injury, etc.;

2. Stem cell transplantation**Immune system diseases such as: diabetes, dermatomyositis, muscle weakness, vascular disease, sclerosis, leukemia, etc.;

3. Stem cell transplantation**Other diseases: such as liver disease, liver cirrhosis, femoral head necrosis, etc.;

Immune cells**, first of all, choose seed immune cells, after the seed immune cells have good activity and reliable quality, then a large number of copies and clones, and then infuse back to the patient, such immune cells ** must be very effective, there is no objection. Nowadays, high-tech researchers, seed immune cells are isolated and extracted from umbilical cord blood, such as extracting high-efficiency NK cells from umbilical cord blood, CIK cell activity is particularly good, after a large number of replication and cloning, it can be given to any cancer patient**, such cells**, will be very effective for everyone. In particular, tumor surgery, post-radiotherapy and chemotherapy prophylaxis are no incomparable means.

There are two methods of cell **.

a.Sex cell therapy such as therapy and somatic cells**.

b.Genetics and nurture.

c.In vitro** and in vivo**.

d.Placenta** and Pattern Pregnancy**.

Correct answer: c

The role of immune cells**:

1. Immune cells can induce autologous antiviral immune response through in vitro culture, proliferation, and activation, and once the human antiviral immunity is activated, it will continuously produce antiviral substances to kill the virus.

2. Most of the T cells that have the effect of killing tumor cells become memory cells in the body after activation, and are stored in lymphoid tissues, which provides long-term protection for the complete removal of tumor cells and the prevention and treatment of metastasis.

Its main process is to isolate immune T cells from cancer patients, use genetic engineering technology to add a chimeric antibody that can recognize tumor cells and activate T cells to kill tumor cells at the same time, and then expand a large number of CAR T cells through in vitro culture, and then infuse the cells back into the patient.
