When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).
They become plasma cells

What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
A persons blood type depends on the presence or absence of certain proteins called?
A & B antigens on the surface of the read blood cells
What are the blood types in terms of antigens and antibodies?
"there are at least 24 blood groups and more then 100 antigens that ca be detected on the surface of red blood cells"- from A&P Book.
Do b cells destroy cancer cells?
No, cancer cells express self antigens, so your body cannot recognize it as foreign or dangerous.
How does a B cell tell the difference between an invader cell and a body cell?
Antigens work as bar-codes to help the immune system differentiate between body cells and pathogens. Normally the body will not attack its own cells, but is programmed to attack those with foreign antigens.
After birth B cells change to immature B cells in?
After birth B cells change to immature B cells in follicular B lymphocytes.
After birth B cells change to immature B cells in-?
After birth, B cells change to immature B cells in the bone marrow.
What types of antigens are recognized by B cells?
Processed fragments of protein antigens displayed on surfaces of body cells.
Do T- Cells respond to antigens by becoming plasma cells?
No. B-Cells do.
What are antigens determining blood type carried on?
Antigens, by definition, cause the body to produce antibodies which act against them. You inherit certain antigens which are on your red blood cells. Sometimes these antigens are absent from your RBC. If you are type B, you have B antigens. Type A has A antigens, AB has AB antigens and type O has no antigens. If you are type AB, you can receive AB blood from some one else.
What do b cells make when they recognize antigns?
B cells make antibodies when they recognize antigens.
What is an example of a self antigen?
A or B antigens of blood cells
B lymphocytes exposed to antigens can transform into plasma cells and produce large quantities of antibodies?
True
What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
Foreign antigens pressed into the plasma membrane are recognized by what?
helper T cells B cells so the answer is B for Plato users
What process provides many b cells and t cells that are activated against specific antigens?
Clonal expansion is the process that provides many B cells and T cells that are activated against specific antigens. Clonal expansion is what provides the immune system its strength.
What is agglutination in biology?
agglutination is when B-lymphocytes, more specifically plasma B-cells, link antigens together using the binding sites on the antigens. This prepares the antigens for phagocytosis or perforation from a killer T-cell
