The presence of which immunoglobulin may cause complications during pregnancy?
D. IgG is able to cross into the maternal placenta and attack the fetal cells. IgA is the main immune component found in tears. IgE is involved in Type 1 Hypersensitivity reactions which cause the degranulation of mast cells. IgD is found on the plasma membranes of immature B-cells. IgM is the first antibody produced in response to a novel antigen. It is the largest and is capable of producing IgG.

Which of the following cells does NOT require an antigen presenting cell when responding to antigens?
A. Natural Killer cells do not require an antigen presenting cell to attack antigens. NK cells serve as the rapid response team for antigens that have yet to be phagocytosed. The remaining cells are part of a specific immunity response.

Which of the following mediators is released by helper T cells in order to promote further growth and differentiation of T cells?
D. Interleukin 2 is released by helper T cells in response to antigen binding. This release, paired with binding of helper T cells to Class II MHC, stimulates the production of more immune factors.

_________ is the process by which complement proteins bind to an antigen to trigger phagocytosis of the cell.
B. Opsonization is the process by which complement proteins cover an antigen to initiate the immune system. Opsons alert the immune system to phagocytose the target cell.
