2021-04-25 · People with IgG deficiency are more likely to get infections. IgG deficiencies can occur at any age. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies. These antibodies are made by B cells and plasma cells. They are let loose throughout the body to help kill bacteria, viruses, and other germs.

Showed that the inclusion of IgA to the typical IgM and IgG serological test improves the performance. 3. Revealed the kinetics of IgM, IgA, IgG antibody isotypes in 

IgM is one of the first antibodies produced during infection. It can be expressed in monomeric form on the surface of B lymphocytes or found circulating in the blood and lymphatic fluid in pentameric form. The IgM pentamer consists of 5 antibodies joined together to form a ring-like-structure. Immunoglobulin M (IgM) is also one of the first antibodies recruited by the immune system to fight infection. IgM populations rise very quickly when the body is first confronted with an infectious organism, and then they plummet as IgG antibodies take over. It is assumed that IgM is the first antibody produced in response to the infection whereas IgG, which is synthesized later but shows enduring presence, has an impact on long-term immunity. Serum IgM antibodies are pentameric and have 10 binding sites whereas serum IgG and IgA are mainly monomeric with 2 binding sites.
