Where Is IgG Produced? Understanding Immunoglobulin G Production

Learn about the production of Immunoglobulin G (IgG) and its vital role in the immune system.

280 views

Immunoglobulin G (IgG) is primarily produced by plasma cells, which are specialized white blood cells. These plasma cells are formed from B cells (a type of lymphocyte) in the bone marrow. Once activated by encountering an antigen, B cells differentiate into plasma cells, which then secrete large quantities of IgG antibodies. These antibodies play a crucial role in the body's immune response by neutralizing pathogens like bacteria and viruses.

FAQs & Answers

  1. What is the function of IgG in the immune system? IgG antibodies play a crucial role in identifying and neutralizing pathogens, such as bacteria and viruses, thereby supporting the immune response.
  2. How are plasma cells formed? Plasma cells are formed from B cells that arise in the bone marrow when they encounter an antigen and undergo differentiation.
  3. What are the different types of immunoglobulins? There are five main types of immunoglobulins: IgG, IgA, IgM, IgE, and IgD, each with specific functions in the immune response.
  4. Can IgG levels be measured? Yes, IgG levels can be measured through blood tests to assess immune function and diagnose various conditions.
