An antibody (Ab), also known as an immunoglobulin (Ig), is a large Y-shaped protein produced by B-cells that is used by the immune system to identify and neutralize foreign objects such as bacteria and viruses .
3
how are antibodies used in
1
The antibody recognizes a unique part of the foreign target, called an antigen .
3
how are antibodies used in
1
Each tip of the "Y" of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision.
3
how are antibodies used in
1
Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system, or can neutralize its target directly (for example, by blocking a part of a microbe that is essential for its invasion and survival).
3
how are antibodies used in
0
Each antibody binds to a specific antigen ; an interaction similar to a lock and key.
3
how are antibodies used in
0
The production of antibodies is the main function of the humoral immune system .
3
how are antibodies used in
0
Antibodies are secreted by a type of white blood cell called a plasma cell .
3
how are antibodies used in
0
Antibodies can occur in two physical forms, a soluble form that is secreted from the cell, and a membrane -bound form that is attached to the surface of a B cell and is referred to as the B cell receptor (BCR).
3
how are antibodies used in
0
The BCR is only found on the surface of B cells and facilitates the activation of these cells and their subsequent differentiation into either antibody factories called plasma cells , or memory B cells that will survive in the body and remember that same antigen so the B cells can respond faster upon future exposure.
3
how are antibodies used in
0
In most cases, interaction of the B cell with a T helper cell is necessary to produce full activation of the B cell and, therefore, antibody generation following antigen binding.
3
how are antibodies used in
0
Soluble antibodies are released into the blood and tissue fluids, as well as many secretions to continue to survey for invading microorganisms.
3
how are antibodies used in
0
Antibodies are glycoproteins belonging to the immunoglobulin superfamily ; the terms antibody and immunoglobulin are often used interchangeably.
3
how are antibodies used in
0
Antibodies are typically made of basic structural units—each with two large heavy chains and two small light chains .
3
how are antibodies used in
0
There are several different types of antibody heavy chains, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess.
3
how are antibodies used in
0
Five different antibody isotypes are known in mammals, which perform different roles, and help direct the appropriate immune response for each different type of foreign object they encounter.
3
how are antibodies used in
0
Though the general structure of all antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with slightly different tip structures, or antigen binding sites, to exist.
3
how are antibodies used in
0
This region is known as the hypervariable region.
3
how are antibodies used in
0
Each of these variants can bind to a different antigen.
3
how are antibodies used in
0
This enormous diversity of antibodies allows the immune system to recognize an equally wide variety of antigens.
3
how are antibodies used in
0
The large and diverse population of antibodies is generated by random combinations of a set of gene segments that encode different antigen binding sites (or paratopes), followed by random mutations in this area of the antibody gene, which create further diversity.
3
how are antibodies used in
0
Antibody genes also re-organize in a process called class switching that changes the base of the heavy chain to another, creating a different isotype of the antibody that retains the antigen specific variable region.
3
how are antibodies used in
0
This allows a single antibody to be used by several different parts of the immune system.
