An infection or contact with a pathogen is an example of what type of immunity?
This antibody remains in the blood even after antibody levels are no longer elevated.
True or false: antibody structure is identical to the antibody receptor of their progenitor cell.
This is the process in which antigens cross-link, causing them to clump and precipitate.
A vaccine or a dead or attenuated pathogens is an example of what type of immunity?
This method of destruction results in the blocking effects of toxins and prevention of attachment to body cells.
Proliferation of other T cells and B cells that have already been bound to an antigen is regulated by which immune cell?
Which cells proliferate during the secondary antibody response, resulting in exponential growth of the antibody titer?
True or false: the secondary response to a re-exposed antigen is faster and more intense.
Immobilization of bacteria results in the destruction of what?
True or False: IL-2 can be released by macrophages before IL-1 is released.
IL-2 sets up a positive or negative feedback in order to encourage T cell division?
Do antibodies destroy antigens?
IL stands for:
Do Helper T cells attack and eliminate antigens?
The only type of T cells that directly attack and kill other cells are:
True or false: Cytotoxic cells circulate the body in search of body cells that display antigens to which they have been sensitized.
Each antibody has a unique variable region that contains the:
Activated Cytotoxic T cells that use granulysin and perforin allow the infected body cell they attack to undergo:
Antibodies passing from the mother to the fetus via the placenta or breat milk to the infant is an example of what type of immunity?
True or false: the primary response to an antigen is instant.
IL-2 is used therapeutically to enhance the body's defense against what?
Helper T cells must be primed by a presented antigen in order for it to start doing its job. Would there be an immune response without Helper T cells?
IL-1 and IL-2 are examples of what?
Antibodies are also called:
The antibody that has the largest population in the body is:
Along with plasma cells, B cells differentiate into:
Another name for Killer T cells is:
Cytotoxic T cells have two mechanisms. One mechanisms releases granzymes while the other releases perforins. The mechanisms that utilizes granzymes cause the infected cell to under
This antibody is the only one that can cross the placenta:
An injection of immune serum is a type of what kind of immunity?
T cells leave the lymphatic system. Do B cells?
T cells bind to which type of cells that have found antigens in the lymph?
Once a B cell is activated by a binding antigen, it produces what?
This type of immunity has an natural and artificial type, along with passive and active subtypes.
Inactive B cells encounter 'free' antigens in lymph or ISF, bind to them and become:
Do antibodies leave the lymphatic system?
True or false: B cells produces antibodies.
