T cells bind to which type of cells that have found antigens in the lymph?
An injection of immune serum is a type of what kind of immunity?
True or False: IL-2 can be released by macrophages before IL-1 is released.
The only type of T cells that directly attack and kill other cells are:
Activated Cytotoxic T cells that use granulysin and perforin allow the infected body cell they attack to undergo:
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-2 is used therapeutically to enhance the body's defense against what?
This antibody is the only one that can cross the placenta:
True or false: antibody structure is identical to the antibody receptor of their progenitor cell.
This method of destruction results in the blocking effects of toxins and prevention of attachment to body cells.
Each antibody has a unique variable region that contains the:
This is the process in which antigens cross-link, causing them to clump and precipitate.
Inactive B cells encounter 'free' antigens in lymph or ISF, bind to them and become:
True or false: B cells produces antibodies.
IL-2 sets up a positive or negative feedback in order to encourage T cell division?
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
Antibodies are also called:
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?

Along with plasma cells, B cells differentiate into:
This type of immunity has an natural and artificial type, along with passive and active subtypes.
An infection or contact with a pathogen is an example of what type of immunity?
Which cells proliferate during the secondary antibody response, resulting in exponential growth of the antibody titer?
Proliferation of other T cells and B cells that have already been bound to an antigen is regulated by which immune cell?
A vaccine or a dead or attenuated pathogens is an example of what type of immunity?
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?
Do Helper T cells attack and eliminate antigens?
IL stands for:
T cells leave the lymphatic system. Do B cells?
Do antibodies leave the lymphatic system?
This antibody remains in the blood even after antibody levels are no longer elevated.
IL-1 and IL-2 are examples of what?
True or false: Cytotoxic cells circulate the body in search of body cells that display antigens to which they have been sensitized.
The antibody that has the largest population in the body is:
Once a B cell is activated by a binding antigen, it produces what?
