How do cells involved in the humoral response respond to antigen presentation on the surface of a B cell?
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies.
When a B or T cell is primed by an interaction with its particular antigen the cell does what?
grows, divides, and differentiates further
Compare and contrast the roles of B cells T helper cells Th cells and cytotoxic T cells Tc cells in your immune system?
b-cell- humeral- antibody based response to antigen t-cell - cell mediated response to antigen both are components of the adaptive immune system
What is the basic principle of blood transfusion?
Blood type A have antigen A and anti- body B Blood type B have antigen B and anti- body A Blood type AB have antigens A and B and no anti- body Blood type O do not have antigen but have anti- bodies A and B
When in its life cycle does a B cell first exhibit its particular surface antibody?
It first exhibits its particular surface antibody before it ever encounters an antigen.
How do cells involved in the humoral response respond to antigen presentation on the surface of a B cell?
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies.
When do lymphocytes become immunocompetent?
each lymphocyte must become able (competent) to recognize its one specific antigen bye binding to it. this ability is called immunocompetence.
Macfarlane burnet theory about antigen antibody reaction?
The Burnet theory about antigen antibody reaction is a basic concept about how we make antibodies specific to a foreign substance which has the ability to induce an immune response (antigen). Each B cell displas one unique type of B cell receptor on their surface (which is basically a membrane bound antibody). Therefore many B cells, each expressing its own type of B cell receptor are needed to cover the inexhaustable number of antigens that are possible, in the hope that one type of B cell receptor will be able to recognise the shape of that antigen. If one B cell does recognise the antigen in question, then this B cell will become activated to make many clones of itself, which will obviously carry identical B cell recptors which fit the antigen. |Therefore the clonal selection theory by Burnet is about antibody antigen interactions which result in the 'best-fit' B cell receptor inducing a reaction to tell the B cell carrying the receptor to multiply and produce lots of identical antibodies which can then be secreted to bind to the antigen they are specific for.
What are the four phases of immune response?
I'm unsure what you mean by 8 steps of the immune system but here is what i can tell you: The two basic types on immune cells are Leukocytes: 1-Phagocytes: Cells that chew up invading organisms 2-Lymphocytes: Cells that allow the body to remember and recognize the invader and the chemicals used to kill it
Antigens cause immature B cells to?
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
Where would a B cell not be likely to meet its antigen?
spleen
Which cell is known as antigen presenting cell?
Dendritic cells,macrophages, B cells
What is the cell that produce antibodies to fight a specific antigen?
It is the B-cells.
What the difference between a b cell and a b memory cell?
A plasma B cell is a B cell that has been activated to proliferate and produce antibodies against a specific antigen. A memory B cell is a B cell that lives a long time after an infection to provide long lasting immunity against that specific antigen. They both originate from the same B cell in your secondary lymph system. Once activated the specific B cell will proliferate into plasma B cells and memory B cells.
How are the roles of b and t cells different how are their roles similar?
Both are T and B lymphocytes are produced in bone marrow, but B lymphocytes mature in bone marrow and are part of the humoral response, while T lymphocytes mature in the thymus gland and are part of the cell mediated response.
Why does a macrophage place antigens on its surface?
When a macrophage engulfs a foreign antigen, it phagocytizes it (or breaks it down) using enzymes. The fragments (called epitopes) of the original antigen are transported to the cell surface so that helper T-cells that specifically match the antigen can recognize it. When that happens, the helper-T cells are able to trigger a specific immune response to that exact antigen by stimulating more helper-T cells to be produced and by triggering B-cells to secrete antigen-specific antibodies that mark infected cells for destruction by killer T-cells.
When a B or T cell is primed by an interaction with its particular antigen the cell does what?
grows, divides, and differentiates further
