It is the B-cells.
A diverse array of antibodies can be generated against a single antigen through a process called somatic hypermutation. This process allows B cells to produce a wide range of antibodies with different binding affinities to the antigen, increasing the chances of finding an effective antibody to neutralize the antigen.
If a person's immune system is producing antibodies against a specific antigen, then that person has a positive or active immunity toward that antigen. If a person has merely been injected with antibodies but does not produce them, that is a passive immunity.
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.
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. If you get a vaccine for rubella, the antibody formed will not act against mumps (another virus).
With active immunity, the body has cells that produce antibodies to antigens composed of amino acids. The antigen could be a protein itself, or on a virus or bacteria. Once the body has a cell that can produce antibodies to this antigen, it differentiates into memory cells and plasma cells, which are the factories that produce the antibodies. With passive immunity, just the antibodies are given, such as an injection. Mothers also confer passive immunity to their children through breast milk. IgA (one of the 5 antibody classes) is secreted. This is temporary as it will bind the antigen, but will not induce production of their own protective antibodies.
Plasma cells proliferate and produce antibodies against an antigen during humoral immunity.
There are various cells and organs that plays a vital role in the production of antibodies. Primarily the white blood cells also called as lymphocytes converts to immunoblasts and then convert to plasma cells, from which the antibodies are thus produced. T-cells and B-cells are antigen specific and produce the antibodies based on the structure and pathogenticity of an antigen. The immune response varies from one antigen to the other.
Its the antigen in a particular foreign body or pathogen that the body recognizes as "allo" or unfamiliar.. Maybe even harmful. So antibodies are produced against these antigens. And since they are 'neutralizing antibodies' it follows that the antigens they bind to are 'neutralizing antigens'
Type A blood will produce antibodies against B antigens.
No, plasma cells develop from B cells after exposure to an antigen. T cells play a role in activating B cells to differentiate into plasma cells and produce antibodies. Plasma cells are responsible for producing large amounts of antibodies specific to the antigen encountered.
Helper T cells recognize the receptor-antigen complex and cause plasma and memory cells to be produced to then produce antibodies.
