Examples of immunize in the following topics:
-
Natural Active Immunity
- Naturally acquired active immunity occurs when a person is exposed to a live pathogen, develops the disease, and then develops immunity.
- Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or previous infection, or by other non-immunological factors.
- Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response.
- Immunization (commonly referred to as vaccination) is the deliberate induction of an immune response, and represents the single most effective manipulation of the immune system that scientists have developed .
- The principle behind immunization is to introduce an antigen, derived from a disease-causing organism, that stimulates the immune system to develop protective immunity against that organism, but which does not itself cause the pathogenic effects of that organism.
-
Passive Immunization
- Passive immunization can be exogenously administered (artificial) or transferred from mother to fetus (natural).
- There are two types of passive immunity: artificial and natural .
- For the newborn to have lasting protection, active immunity must be received.
- Natural immunity occurs through contact with a disease causing agent, when the contact was not deliberate, where as artificial immunity develops only through deliberate actions of exposure.
- Passive immunity is short lived, and usually lasts only a few months, whereas protection via active immunity lasts much longer, and is sometimes life-long.
-
Active and Passive Humoral Immunity
- The humoral immune response is the aspect of immunity mediated by secreted antibodies.
- The humoral immune response (HIR) is the aspect of immunity mediated by secreted antibodies produced by B cells.
- Active humoral immunity refers to any form of immunity that occurs as a result of the formation of an adaptive immune response from the body's own immune system.
- Passive immunity is the transfer of active humoral immunity in the form of ready-made antibodies from one individual to another.
- Maternal passive immunity is a type of naturally-acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus by its mother during pregnancy.
-
Primary and Secondary Antibody Responses
- The immune system protects organisms from infection first with the innate immune system, then with adaptive immunity.
- Innate immune systems are found in all plants and animals.
- Both innate and adaptive immunity depend on the ability of the immune system to distinguish between self and non-self molecules.
- This type of immunity is both active and adaptive because the body's immune system prepares itself for future challenges.
- Active immunity often involves both the cell-mediated and humoral aspects of immunity as well as input from the innate immune system .
-
Types of Adaptive Immunity
- The adaptive immune response is mediated by B and T cells and creates immunity memory.
- The adaptive immune system mounts a stronger, antigen-specific immune response after the innate immune response fails to prevent a pathogen from causing an infection.
- There are two subdivisions of the adaptive immune system: cell-mediated immunity and humoral immunity.
- Cell mediated immunity is controlled by type 1 helper T cells (Th1) and cytotoxic T cells.
- Antibodies provide a number of functions in humoral immunity.
-
Overview of the Immune System
- This process of acquired immunity is the basis of vaccination.
- Innate immune systems are found in all plants and animals.
- Adaptive immunity is often sub-divided into two major types depending on how the immunity was introduced.
- Both naturally and artificially acquired immunity can be further subdivided depending on whether immunity is induced in the host or passively transferred from an immune host.
- A further subdivision of adaptive immunity is characterized by the cells involved; humoral immunity is the aspect of immunity that is mediated by secreted antibodies, whereas the protection provided by cell-mediated immunity involves T lymphocytes alone.
-
Adaptive Immunity and the Immunoglobulin Superfamily
- Adaptive immunity is stimulated by exposure to infectious agents and recruits elements of the immunoglobulin superfamily.
- The components of adaptive immunity are lymphocytes and their products.
- There are two types of adaptive immune responses: humoral immunity and cell-mediated immunity.
- They are commonly associated with roles in the immune system.
- Describe the role of immunoglobulins in the adaptive immune response, specifically in humoral immunity
-
Artificial Immunity
- Artificial immunity is a mean by which the body is given immunity to a disease by intentional exposure to small quantities of it.
- Immunity is the state of protection against infectious disease conferred either through an immune response generated by immunization or by previous infection or other non-immunological factors.
- Artificially-acquired passive immunity is an immediate, but short-term immunization provided by the injection of antibodies, such as gamma globulin, that are not produced by the recipient's cells.
- Natural immunity occurs through contact with a disease causing agent, when the contact was not deliberate, where as artificial immunity develops only through deliberate actions of exposure.
- Passive immunity is short lived, and usually lasts only a few months, whereas protection via active immunity lasts much longer, and is sometimes life-long.
-
Overview of Adaptive Immunity
- The adaptive immune system works to protect and heal the body when the innate immune system fails.
- The adaptive immune system starts to work after the innate immune system is activated.
- The adaptive immune response occurs a few days after the innate immune response is initiated.
- The major functions of the adaptive immune system include:
- Adaptive immunity is triggered when a pathogen evades the innate immune system for long enough to generate a threshold level of an antigen.
-
Innate Immune Response
- Mammalian immune systems evolved for protection from such pathogens.
- However, we are born with only innate immunity, developing our adaptive immune response after birth.
- Components of both immune systems constantly search the body for signs of pathogens.
- When pathogens are found, immune factors are mobilized to the site of an infection.
- Eosinophils play a variety of roles in the immune response.
