How to distinguish between innate immunity, natural immunity, planned immunity, specific immunity an

Innate immunity","Natural immunity"Essentially the same.

Planned immunization is the specific immunity formed by vaccination with a specific vaccine according to a certain schedule.

Specific immunity is obtained through vaccination, for example, to obtain immunity to one or several specific conditions.

Non-specific immunity is the body's own immunity to all diseases made up of a defense system.

Innate immunity refers to the immunity that people have from birth! Natural immunity is an innate defense. For example, humoral immunity and cellular immunity are both natural immunity!

Planned immunization is based on the monitoring of the flow of infection and the analysis of the situation of susceptible populations, and the planned vaccination of susceptible populations enables them to obtain immunity, so as to achieve the purpose of controlling and eradicating infectious diseases! Specific immunity refers to the protective physiological function that has a certain defensive effect against a specific pathogen. Non-specific immunity refers to a protective physiological function that does not target a specific pathogen, but has a certain defensive effect against a variety of pathogens, and this protective physiological function is called non-specific immunity.

Hee-hee......

Innate immunity","Natural immunity, non-specific immunity"It's the same, it belongs to the second line of defense. It is the function of ordinary white blood cells, such as neutrophils.

Specific immunity is the third line of defense and is the main function of lymphocytes.

Innate immunity, also known as non-specific immunity, has a clear line between innate immunity and specific immunity. Innate immunity is the function of resisting the invasion of pathogenic microorganisms gradually formed by humans in the long-term process of germline development and evolution. Congenital and non-specific.

Specific immunity: It is the immunity obtained by an individual who is infected by pathogenic microorganisms or vaccinated in the course of life. Features:

Acquired, targeting specific pathogenic microorganisms, different from person to person, independent of heredity, specific, with immune memory. Seeing that I'm so tired of typing, the boss will give the best!

Innate immunity is non-specific immunity. The corresponding is the direct destruction of antigens by phagocytes. The name is given because phagocytes can engulf all antigens, not just one type.

Non-specific immunity is the opposite.

Non-specific immunity is divided into cellular immunity and humoral immunity.

In cellular immunity, T cells that mature in the thymus proliferate and differentiate into effector T cells, attacking antigens that have already entered the cell.

In humoral immunity, B cell proliferation and differentiation into plasma cells can occur spontaneously, but, at the same time, T cells release lymphokines to facilitate this process. Plasma cells can secrete antibodies that attack antigens that do not enter the cell.

When bacteria and viruses are amplified in the body, the first thing to start is innate immunity, because innate immunity starts quickly, and it can generally be started in a few hours, but the disadvantage is that the specificity is not strong and cannot be completely killed.

Innate immunity involves cells such as NK that secrete cytokines, as well as some other mechanisms, which will lead to the initiation of specific immunity, which requires cell expansion, so it takes a few days to activate, but it has a strong killing ability and can completely kill pathogens.

Innate immunity and specific immunity are different parts of the human immune mechanism, and they complement each other.

Answer]: Cytokines and humoral factors of non-specific immunity can play a role in specific immunity, such as the antigen presentation function of macrophages; A variety of cells, including macrophages, neutrophils, NK cells, and mast cells, secrete cytokines; Pro-inflammatory and immunomodulatory effects of complement fragments. Conversely, cytokines and humoral factors of specific immunity can also further mobilize non-specific immunity, such as the activation of complement, opsonization and ADCC by antibodies. Lymphocytes secrete cytokines to chemotaxis, activate and enhance the killing function of phagocytic cells and NK cells.

However, when the body encounters pathogens into the old and grandchildren, non-specific immunity and specific immunity are carried out at the same time, and there is no clear boundary between them.
