What is the significance of immunomodulation, and what is the significance of immunity?

Immunomodulators can increase the body's ability to resist disease and increase the body's anti-infection effect.

Immunomodulators activate one or more immunocompetent cells, increasing body specificity.

and non-specific immune function, which can restore weakened immunity.

caused by the condition.

Introduction

It can be used as an adjunct to immunodeficiency diseases or nausea tumors**, and can also improve the body's immunity and improve the body's ability to resist diseases.

Commonly used immunomodulators in clinical practice include BCG ribonucleic acid.

Thymopetin. Oral solution of transfer factors, interferon, polymyocytes, placenta.

Polysaccharides, astragalus polysaccharides and other drugs.

It refers to the interaction between immune cells and immune molecules in the immune system, as well as with other systems such as the neuroendocrine system, so that the immune response is maintained at the most appropriate level in the most appropriate form. Immunomodulation can be likened to the body's symphony orchestra, which is well coordinated - recognizing and clearing antigens, producing immune tolerance to its own components, and maintaining the stability of the internal environment. Poor coordination - pathogenic microbial infection, tumors, autoimmune diseases, immunodeficiency diseases, hypersensitivity reactions.

Our body has a certain resistance to various pathogenic microorganisms (such as bacteria, viruses, etc.) that invade the body and the toxins they produce, which is generally called immunity.

Immunity is a physiological function of the human body, which has a protective effect on the human body, such as the human body's **, mucous membranes and phagocytic cells in the body, and various bactericidal substances, all of which have immune functions against pathogenic bacteria.

Human immunity is an important barrier for the human body to defend against foreign viruses.

It is generally recognized that low immunity increases the likelihood of illness in the human body, especially infants and the elderly. The former's immune system is not yet fully developed, and its resistance to various pathogenic microorganisms is poor, and it is prone to various infectious diseases such as respiratory tract and digestive tract. In the latter, immune function declines due to the gradual decline of the immune system.

When the immune regulation is unbalanced, it is when the immune function is dysfunctional, which will lead to physiological dysfunction and susceptibility to a variety of diseases: such as cold, pneumonia, gastroenteritis, liver disease, kidney disease, diabetes, cardiovascular and cerebrovascular diseases, cancer, etc.

Immune dysfunction is associated with free radical damage. Excess free radicals in the body, acting on cell membranes and organelles, causing structural abnormalities and dysfunction, resulting in reduced immune cell activity, decreased antibody production, and low cellular and humoral immunity.

Through the analysis, it can be seen that the function of immunity refers to the identification and removal of swollen tumor cells in the body, the removal of senescent, dead or damaged cells in the body, and the resistance to the invasion of antigens

Therefore, the answer is: immunity refers to the recognition and removal of tumor cells in the body, the removal of senescent, dead or damaged cells in the body, and the resistance to the invasion of antigens.

The relationship between neuromodulation and immunomodulation is not as pronounced as that between neuromodulation and humoral regulation. Because immune regulation is relatively independent.

But you can understand it with the help of everyday life experience: if a person is overly sad and depressed, then his immunity must be reduced. This may shed light on the relationship between neuromodulation and immunomodulation.

Recent studies have found that the overall coordination between humans and mammals is the result of close cooperation between the nervous system, the endocrine system and the immune system. This is mainly reflected in the following aspects: First, a cell or tissue can have multiple functions.

Recent studies have shown that there are many components in the central nervous system that play a role in regulating immune function, and even confirmed that the brain is also an immune organ; Second, a substance can be either a hormone, a neurotransmitter, or an immunomodulator. For example, the neurotransmitter serotonin 5 can act directly on B cells and T cells, and is therefore an immunomodulatory substance, and thirdly, there is an action and a reaction between the three. The activity of the nervous system governs hormone secretion and immune function, and the latter two can also react on nerve cells.

For example, hypoxia, ischemia, degeneration, and degeneration of nerve cells may be related to pathological changes in the immune system.

The structure and function of the human immune system.

The function of immunity is to prevent viruses from invading the body, of course, this is not all viruses, can not the body has limited immunity, or will, the function of immunity is to prevent viruses and bacteria from invading the body, and will kill.

Immunity is all about providing resistance. The body needs immunity to fight bacterial and viral attacks. To put it simply, immunity is the body's own defense mechanism, which has the function of identifying and destroying germs and viruses.

To put it simply, it is the body's resistance, resistance to the virus.

The three main functions are Defense, Monitoring, and Removal.

Immunity is the self-protection function obtained by people in long-term evolution, we call it the human immune function, this function is very complete and powerful, to sum up, immunity has three major functions for the human body: the first function is to protect the human body from bacteria, viruses and other harmful microorganisms infection, we call this immune defense, the second function of immunity is to remove the body's own aging and dead cells The third function of immunity is to remove cancer cells in the human body in time to prevent the occurrence of cancer, we call it immune surveillance.

The immune system has the role of immune surveillance, defense, and regulation.

In a word, righteousness is stored in the body, and evil cannot be done!

Immunity is a series of physiological or pathological responses in which the body recognizes "self" and "non-self" antigens. Under normal circumstances, it forms a natural immune tolerance to its own antigens and rejects the "non-self" antigen, which is beneficial to the body and can produce anti-infection, anti-tumor and other immune protection effects to maintain the physiological balance and stability of the body. Under certain conditions, immune dysfunction can also produce reactions and outcomes that are harmful to the body, which can lead to diseases such as hypersensitivity reactions, autoimmune diseases, and tumors.

The immune system and its components are the organs that perform innate immunity and adaptive immune functions, and are composed of immune organs, immune cells, and immune molecules.

The three major functions of immunity.

Immune function Physiological (beneficial) Pathologic (harmful).

Immune defenses Removal of pathogenic microorganisms and other antigenic foreign bodies Hypersensitivity reactions (excessive).Immunodeficiency (insufficiency).

Immune homeostasis Removal of damaged or senescent cells Immune surveillance for autoimmune diseases Removal of mutant or aberrant cells Tumorigenesis, persistent viral infection.

Immunity is a physiological function of the human body, which relies on the human body to recognize "self" and "non-self" components, so as to destroy and reject antigenic substances entering the human body, or damaged cells and tumor cells produced by the human body itself, so as to maintain the health of the human body. A state that resists or prevents infection by microorganisms or parasites or other undesirable biological invasions. Immunity involves both specific and non-specific components.

Non-specific components do not require prior exposure and can respond immediately, which can effectively prevent the invasion of various pathogens. Specific immunity is developed during the life of the subject and is immunity specifically against a certain pathogen.

1.The three basic functions of the immune system are: immune defense.

Immune surveillance. Immune homeostasis2

The three basic functions of the immune system manifest themselves in both normal and abnormal situations: a) immune defense.

Normally, prevent the invasion of external pathogens and remove the invaded pathogens, other harmful substances, abnormal immune function, low or deficient, immunodeficiency disease will occur; If the response is too strong or lasts too long, it will lead to damage or dysfunction of the body while eliminating the pathogen, and a hypersensitivity reaction will occur b).

Immune surveillance. Normally, non-self-absorbed components such as tumor cells and senescent and dead cells in the body can be found and eliminated at any time, and the immune monitoring function is low, which can lead to the occurrence of tumors and persistent viral infection, c) immune self-stability.

Normal maintains the stability of the immune system environment through two mechanisms: immune tolerance and immunomodulation, abnormal immune tolerance is broken, and immune regulation function is disordered, which will lead to the occurrence of autoimmune diseases and allergic diseases.
