Question
Place the following statements that describe the 5 steps in an adaptive immune response in the order in which they occur.
-Long lived-immune cells allow the second response to a given microbe to be stronger and faster than the first response
-Adaptive immune cells are born in the bone marrow, then mature in either the bone marrow or the thymus
-Adaptive immune cells use specific receptor proteins to bind to antigens very specifically
-Intracellular signaling pathways are initiated, causing the adaptive immune cell to change cell division, gene expression, and protein translation
-Adaptive immune cells kill invading microbes, either directly or indirectly
Which of the following statements describe Class I MHC molecules, and which describe Class II MHC molecules?
This molecule is expressed on all nucleated cells.
This molecule interacts with proteins expressed on the surface of Cytotoxic T cells.
This molecule is expressed on the surface of Antigen presenting cells.
This molecule is important for activating Helper T cells
This molecule is expressed on the surface of B cells.
This molecule binds to antigens that come from primarily intracellular pathogens
Class I MHC.
Class II MHC
Both Class I and Class II MHC.
Match each immune cell with the method it uses to neutralize a pathogenic microbe that has infected a human
Cytotoxic T cell
Helper T cell
B cell
Natural Killer Cell
Macrophage
Basophil/Mast Cell
kills infected human cells after recognizing antigens displayed on MHC class 1
does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.
phagocytoses microbes after recognizing specific antigens; secretes antibodies
kills infected human cells after recognizing PAMPs on infected cell membranes
Phagocytoses microbes after recognizing PAMPs; acts as an Antigen Presenting Cell to activate another type of immune cell
Does not directly kill microbes; secretes histamine to initiate an inflammatory response.
