Frnds I want to know about the types of Immunoglobulin, if u know rply must, thnx.
-
An antibody, also known as an immunoglobulin, is a large Y-shaped protein used by the immune system to identify and neutralize foreign objects such as bacteria and viruses. The antibody recognizes a unique part of the foreign target, termed an antigen.
They are produced by white blood cells.
They are of five types-
IgA, IgD, IgE, IgG and IgM. They are each named with an "Ig" prefix that stands for immunoglobulin, another name for antibody, and differ in their biological properties, functional locations and ability to deal with different antigens.
IgA- Found in mucosal areas, such as the gut, respiratory tract and urogenital tract, and prevents colonization by pathogens. Also found in saliva, tears, and breast milk.
IgE- Binds to allergens and triggers histamine release from mast cells and basophils, and is involved in allergy. Also protects against parasitic worms.
IgD- Functions mainly as an antigen receptor on B cells that have not been exposed to antigens.It has been shown to activate basophils and mast cells to produce antimicrobial factors
IgG- In its four forms, provides the majority of antibody-based immunity against invading pathogens.The only antibody capable of crossing the placenta to give passive immunity to fetus.
IgM- which is found mainly in the blood and lymph fluid, is the first to be made by the body to fight a new infection.
