Term
|
Definition
| contain only fragments of bacteria that will stimulate a strong immune response |
|
|
Term
|
Definition
| when you actively produce antibodies against an antigen either naturally (getting over an infection) or artifically (vaccine) |
|
|
Term
|
Definition
| resistance against pathogen that acts more effectively upon subsequent infections with the same pathogen; specificty, inducibility, clonality, unresponsiveness to self, memory |
|
|
Term
ADCC
(antibody-dependent cellular cytotoxicity) |
|
Definition
| once antibodies coat the surface of a pathogen, natural killer lymphocytes (NK cells) bind to the Fc region of the antibody and lyse the target cells with perforin and granzyme |
|
|
Term
|
Definition
| molecules that attach pathogens to their target cells |
|
|
Term
|
Definition
| immunological agent that modifies the effect of other agents, such as a drug or vaccine, while having few, if any direct effects when given by itself. |
|
|
Term
|
Definition
| an immediate hypersenstive response against an antigen |
|
|
Term
|
Definition
| (immunoglobulin) proteinaceous antigen-binding molecule secreted by plasma cells |
|
|
Term
|
Definition
| molecule that triggers a specific immune response |
|
|
Term
|
Definition
| (adaptive immune response) a virus infected antigen presenting cell (dendritic cells, B cells, macrophages) goes towards the lymph nodes where it presents the virus epitope with MHC I protein (major histocompatibility complex). |
|
|
Term
|
Definition
| production of host antigens by a parasite, enabling it to avoid detection by the host's immune system. |
|
|
Term
|
Definition
| a weakened virus with reduced ability to cause, infect, or produce disease. |
|
|
Term
|
Definition
| the presence of bacteria in the blood |
|
|
Term
|
Definition
| lymphocyte that arises and matures in the red bone marrow in adultsa and is found primarily in the spleen, lymph nodes; secretes antibodies |
|
|
Term
|
Definition
| T cell with CD4 protein. CD4 receptor binds to the cells with MHCII complexes that have digested some antigen, when bound it activates the cell. One activated, they differentiate into effector (acivate B cell, release cytokines, or memory) |
|
|
Term
|
Definition
| an immune system cytokine that signals leukocytes to rush to the site of inflammation or infection and activate other leukocytes. |
|
|
Term
|
Definition
| part of the innate immunity. complement proteins in blood serum interact with antibodies and other chemical substances to cause the disintegration of foreign cells and enhance other immune functions such as phagocytosis. |
|
|
Term
|
Definition
| part of the antibody that is the same for all antibodies (makes up the Fc region and hinge) |
|
|
Term
|
Definition
| proteins secreted by many types of cells that regulate adaptive immune responses (intercellular mediators). |
