Human iga is an immunoglobulin, an antibody in the human immune system. It is mainly found in the blood, body fluids and mucosal tissues of the human body, and is one of the important defense lines of the body against external pathogens and allergens.

The main role of human iga antibodies is to recognize and bind pathogens in the body, such as bacteria, viruses and fungi, and activate other immune cells, such as macrophages and natural killer cells, so as to clear pathogens and protect the body from infection. Unlike ige antibody, iga antibody mainly exists on mucosal surface and body fluids, so it plays an important role in immune defense in mucosal tissues such as respiratory tract, digestive tract and urogenital tract.

Human iga antibodies are also involved in the immune defense against parasitic infections. For example, during a parasite infection, surface antigens of the parasite can bind to the body’s iga antibodies, activating immune cells and triggering an inflammatory response that helps clear the parasite.

In addition to allergic reactions and parasitic infections, human iga antibodies have been implicated in the occurrence and development of other diseases. For example, some autoimmune diseases (such as ulcerative colitis, Crohn’s disease, etc.) are associated with overproduction of iga antibodies. In addition, some tumors also produce iga antibodies, which may be related to the occurrence and development of tumors.

In short, human iga antibody is an important antibody in the human immune system, which plays an important role in the occurrence and development of allergic reactions, parasitic infections and other diseases.
