Which immunoglobulin class is attached to the external surface of B cells and acts as an antigen receptor of the B cell?

B cells do not contain any antibodies on their surface. Generally, B cells produce all the antibodies in the body is in need of; as instructed by T helper cells (CD4+ cells).

Can a receptor be an antigen?
No, they are entirely two different things. What might stimulate a receptor could be an antigen.
In the primary response to an antigen the first class of antibody to be secreted is?
The class of immunoglobulin to respond to the fist exposure of an antigen is immunoglobulin class M (IgM). While Immunoglobulin G (IgG) would predominate on the second exposure.
In order for a lymphocyte to respond to an antigen the antigen must?
the antigen must bind to the receptor
Is CD4 an adhesion molecule?
The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
What is Antigen binding site of immunoglobulin?
Question is little bit confusing. Anyway I have an answer and hope it make sense to this question. Antibodies binds to a part of an antigen which is known as Epitope.
Does an antibody attached to an antigen make it harmless?
When an antibody attaches onto an antigen it destroys the antigen to help your body fight off a disease.
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 is the difference between an antigen and pathogen?
an aepitope is the part of an antigen where antibodiy or lymphocyte receptor binds
What is multiple antigen peptide?
Multiple antigen peptides (MAPs) consist of highly branched lysine dendrimer core and many copies of antigen peptides chemically attached to its ends
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
What is the alternative name for antibody?
An antigen is any substance that causes your immune system to produce antibodies against it. An antigen may be a foreign substance from the environment, such as chemicals, bacteria, viruses, or pollen. It could be also called an irritant.
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.
