Three characteristics for an antigen to be immunogenic? |
Large |
|
Cells are ________ of antigens |
Cells are mosaics of antigens |
|
Marker of Identity |
Antigen |
|
Why wouldn't an O antigen cause a response? |
It's not big or complex enough |
|
A, B, and O are all _______ |
antigens, immunogens |
|
Two divisions of the immune system? |
Innate and acquired
|
|
What WBCS are associated with each division of the immune system? |
Innate = Segmented Neutrophils |
|
What are the two divisions of the acquired division of the immune system? |
Humoral (Antibodies method of attack) |
|
What is the method of attack for the innate immune system? WBC? |
Segmented Neutrophils |
|
Major Cell of Humoral? |
B-Cell (B Lymphocyte) |
|
Central Lymphoid organs? |
Central: Bone marrow and Thymus (Thymus is dorsal to sternum) |
|
What occurs in the central lymphoid organs? |
Central = Lymphocytes gain specialty (making antibodies, perforin, etc) |
|
What does the bone marrow produce? what does the thymus produce? |
Bone marrow = Immunocompetent (committed) B Cells |

What are the types of T-cells? What do they use? |
Cytotoxic (TC) |

Another name/abbreviation for antibody? |
Immunoglobulin (ig) |
|
What does a committed B-Lymphocyte do that a non-committed can't do? |
It has immunological memory that recognizes antigens |
|
What happens during Clonal Selection? |
Proliferation (Dividing) |
|
Committed lymphocytes differentiate into what two types of cells? |
Effector cells - Make antibodies, respond to infection. Fight immediately. Memory cells - High affinity for next exposure. Don't fight the first time but wait for next exposure. |
|
What does AIDS/HIV stand for? |
AIDS = Acquired immune deficiency syndrom |
|
What portion of the immune system does aids/hiv attack? |
Acquired |

Two serological diagnostic tests for HIV? |
ELISA - Take serum and look for IG against HIV |
