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
What are the progeny cells of a B-cell clone called?
The progeny cells of a B-cell clone are called plasma cells. Plasma cells are responsible for secreting large quantities of antibodies specific to a particular antigen.
How b cell responds to the initial antigen challenge?
Upon initial antigen challenge, B cells with specific surface receptors that match the antigen become activated. These activated B cells differentiate into plasma cells that produce antibodies targeting the antigen. Additionally, some B cells can also become memory B cells to mount a faster and more robust immune response upon subsequent exposures.
What does not serve as an antigen-presenting cell?
Red blood cells do not serve as antigen-presenting cells. Antigen-presenting cells include dendritic cells, macrophages, and B cells, which play a crucial role in initiating immune responses by presenting antigens to T cells.
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
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.
What are the differences between Bcell receptors and Tcell receptors?
there are different types of b cell and t cell. both are lymphocytes, a subclass of white blood cell. the t cells are mainly used in identifying antigens and releasing chemicals which attact macrophages (big immune cells which 'eat' antigens), to destroy the antigen. b cells are used in the production of antibodies. when they encounter a new antigen, plasma cells and memory cells are formed from the division of a b cell. the memory cell remembers the antigen and which antibody to use, while the plasma cell makes the antibodies to fight a particular antigen or class of antigens
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.
Where would a B cell not be likely to meet its antigen?
spleen
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
What are antibodies made by?
Antibodies are made by a type of white blood cell called B cells. When the body detects the presence of a foreign substance (antigen), B cells are activated to produce antibodies specific to that antigen. These antibodies work to help the immune system recognize and eliminate the invader.
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.
