Types of immunization
|
Passive immunization--old/outdated
Active immunization--typical Recombinant DNA immunity--recent |
|
|
Passive immunity
|
Person receives antibodies from another source, temporary immunity because own B-cells are not producing antibodies.
|
|
|
Active immunization
|
Exposure to a pathogen's surface markers. B-cells make antibodies.
Exposure can be through disease or injection. Can be dangerous if whole antigen is accidentally injected, instead of just surface marker. |
|
|
Active immunity through recombinant DNA
|
Genes that code for surface marker of antigen are inserted into the chromosome of harmless cells, like yeast, causing it to produce MHC marker of antigen. Injected, causing immune response and creating memory cells.
|
|
|
Monoclonal antibodies
|
Commercially prepared antibodies, made from B-cells. Bind to specific cells.
|
|
|
Immunotherapy
|
Increases defenses against cancer and disease by manipulating body's natural immunity.
|
|
|
Immunotherapy for breast cancer
|
Monoclinal antibodies are injected and they bind to surface proteins on breast cancer cells, attracting macrophages.
|
|
|
Immunotoxins
|
Made by binding a monoclinal antibody with a toxin.
Bind to cancer or HIV infected cells, block basic functions and gradually kill target cell. |
|
|
Interferon cytokine
|
Prevents viruses from multiplying and increases macrophage activity. Used on hepatitis C, HIV, and many more.
