Antibodies
Made by your body to target other foreign entities
Antibodies are also known as?
Immunoglobulins (Ig)
Antigen
Foreign molecule that illicit an immune response and binds to an antigen
What foreign molecules qualify as an antigen?
- ) must be a protein or unique carbohydrates branching
- ) must be Large (10,000 daltons)
- ) bind to surface of pathogen or secreted (like a toxin)
What is the third line of defense in your immune system?
Acquired immunity
Which type of lymphocyte makes antibodies
B cells
Each B cell can make only one type of..?
Antibody
What is an Naive B cell?
A B cell that has never seen its antigen
What does MHC for?
Major Histo Compatibility Complex
What is the role for MHC?
Acts as a display case for antigens
How is penicillin an antigen?
It gets “piggybacked” from a bigger molecule in the your blood
This is called a HAPTEN molecule
What is a hapten molecule?
A small molecule that can attached/carried on a larger protein that is recognized as yourself which it is then seen as an antigen
True or false; small molecules can become antigens?
True- by being carried on a larger self protein
What is an example of a Hapten molecule?
Penicillin
True or false: anti-bodies are inside a human cell
False, they are outside/extra cellular .
they need to be accessible to antigens that are in your blood and lymphatic system
