Each antibody has a unique variable region that contains the:
Once a B cell is activated by a binding antigen, it produces what?
True or false: B cells produces antibodies.
The antibody that has the largest population in the body is:
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: antibody structure is identical to the antibody receptor of their progenitor cell.
This antibody is the only one that can cross the placenta:
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?
Proliferation of other T cells and B cells that have already been bound to an antigen is regulated by which immune cell?
True or false: the secondary response to a re-exposed antigen is faster and more intense.
An infection or contact with a pathogen is an example of what type of immunity?
True or false: the primary response to an antigen is instant.
Along with plasma cells, B cells differentiate into:
Another name for Killer T cells is:
Do antibodies leave the lymphatic system?
This antibody remains in the blood even after antibody levels are no longer elevated.
Immobilization of bacteria results in the destruction of what?
Do Helper T cells attack and eliminate antigens?
Antibodies are also called:
This method of destruction results in the blocking effects of toxins and prevention of attachment to body cells.
IL-2 sets up a positive or negative feedback in order to encourage T cell division?
T cells leave the lymphatic system. Do B cells?
This type of immunity has an natural and artificial type, along with passive and active subtypes.
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.
An injection of immune serum is a type of what kind of immunity?
IL-2 is used therapeutically to enhance the body's defense against what?
Activated Cytotoxic T cells that use granulysin and perforin allow the infected body cell they attack to undergo:
True or False: IL-2 can be released by macrophages before IL-1 is released.
Which cells proliferate during the secondary antibody response, resulting in exponential growth of the antibody titer?
T cells bind to which type of cells that have found antigens in the lymph?
IL stands for:
Inactive B cells encounter 'free' antigens in lymph or ISF, bind to them and become:
The only type of T cells that directly attack and kill other cells are:
This is the process in which antigens cross-link, causing them to clump and precipitate.
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
Do antibodies destroy antigens?
A vaccine or a dead or attenuated pathogens is an example of what type of immunity?
