What antibody is the primary one produced when an antigen is taken up by an M cell?
|
IgA; essential for mucosal immunity
|
|
Which T cell type is generally involved when a B cell reacts with an antigen and produces antibodies against the antigen?
|
T Cytotoxic: recognizes endogenous antigens on the target's cell surface that are combined w/ MHC
|
|
Which is the T cell type that is generally involved in allergic reactions?
|
T helper cells: interact with an antigen before B cells interact with the antigen; specifically TH2 cells, produce IgE antibodies
|
|
What is another name for apoptosis, one that describes its function?
|
Programmed cell death; cells cut genome into fragments; induced by Granzymes
|
|
T-Regulatory Cells
|
Lymphocytes that appear to suppress other T cells
|
|
Are dendritic cells considered primarily part of the humoral or the cellular immune system?
|
Cellular immunity; engulf microbes and transfer them to lymph nodes for display to T-cells (Antigen Presenting Cell)
|
|
How does the natural killer cell respond if the target cell does not have MHC class I molecules on its surface?
|
It kills the cell by causing pores to form in it.
|
|
What makes a natural killer cell, which is not immunologically specific, attack a particular target cell?
|
If the target cell does not present MHC (major histocompatibility complex)
|
|
What is the function of cytokines?
|
Small proteins that are chemical messengers that mediate the communication between different cells; regulate immune response

|
|
Is the anamnestic response primary or secondary?
|
Secondary: a rapid rise in antibody titer following exposure to an antigen after the primary response
|
|
What type of adaptive immunity is involved when gamma globulin is injected into a person?
|
Artificially acquired, passive immunity: injection of antibodies, rather than antigens, into body
