IMMUNOSERO Flashcards
The study of all aspects of the immune system, including its structure and function.
Immunology
It deals with the response of an organism to antigenic challenge and its recognition of what is self and non-self.
Immunology
A division of immunology that specializes in the laboratory detection and measurement of antigens and antibodies.
Serology
The ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.
Immunity
a substance that is capable of stimulating an immune response
Antigens
a foreign agent that is not considered by the body as self.
Ex. bacteria, viruses, allergens
Antigens
proteins made by plasma cells in response to an antigen
ANTIBODIES
skin (epithelial cells), mucous membrane (sebum, saliva, tears, stomach acid, normal flora)
First line
consists of particular cells (monocytes, macrophages, neutrophils, tissue dendritic cells, and mast cells.) and soluble substances in the blood (complement, lysozyme, interferon). The inflammatory response enhances the activation of white blood cells.
Second line
direct fighters of foreign invaders and also produced cytokines, which are biological substances that help activate other parts of the immune system.
T-Lymphocytes
produce antibody molecules that can latch on and destroy invading viruses or bacteria.
B-Lymphocytes
memorize the characteristics of the antigen that activated their parent B cell during initial infection such that if the memory B cell later encounters the same antigen, it triggers an accelerated and robust secondary immune response. (vaccination)
B memory cells
forms a 3rd line defense that allows the body to recognize, remember, and respond to a specific stimulus, an antigen.
ADAPTIVE
can result from natural exposure in response to an infection (natural) or from an intentional vaccination with an antigen-bearing microorganisms (artificial)
ACTIVE
should stimulate the production of antibodies in a person with the disease
ACTIVE
a person is given antibodies to a disease rather than producing them through his or her own immune system.
PASSIVE
○ if organisms have penetrated the first line of defense.
○ nonspecific
○ this 2nd line of defense consists of particular cells (neutrophils, tse basophils, macrophages) and soluble substances in the blood (complement, lysozyme, interferon)
○ immune response
○ Inborn ( given to us at birth/ fertilization)
○ biologic
INNATE
is an impairment of the immune system
Immunodeficiency
