Immunity
|
Immune system consists of cells and tissues that defend the body against specific pathogens
|
|
Specificity
|
Enables the immune system to identify particular pathogens and distinguish self molecules and non-self molecules
|
|
Memory
|
The immune system has a memory for encounters with previously identified pathogens
|
|
Cellular immunity
|
Uses lymphocytes to directly attack and destroy foreign cells that are infected by bacteria or virus
|
|
Humoral immunity
|
Uses antibodies to "label" pathogens for destruction by other mechanisms
|
|
Naturally acquired active immunity
|
Occurs when antibodies or t-cells are produced in response to particular pathogen
|
|
Naturally acquired passive immunity
|
Is a temporary immunity from the natural transfer of antibodies between a immunized donor and a non-immunized recipient
|
|
Artificially acquired active immunity
|
Results from vaccination
|
|
Vaccine
|
Dead pathogens that promote body to produce antibodies or t-cells
|
|
Artificially acquired passive immunity
|
Temporary immunity from an injection of serum that contains antibodies that were produced outside of the body
|
|
Horse serum
|
Used for snake bites
|
|
Antigens
|
Antibody generating molecule
-shows immunogenicity and reactivity |
|
Immunogenicity
|
Ability to provoke immune system
|
|
Reactivity
|
Ability to interact with specific antibodies or cells
|
|
Examples of antigens:
|
Microbes, part of microbe, bacterial cell, walls of bacterial toxins
