Discover the importance of IgG antibodies and what they bind to in immune defense.

114 views

IgG is an antibody that primarily binds to antigens such as bacteria, viruses, and toxins. This binding helps neutralize pathogens and marks them for removal by immune cells. By recognizing and attaching to these harmful particles, IgG plays a crucial role in the body's immune defense system.

FAQs & Answers

  1. What are the main functions of IgG antibodies? IgG antibodies primarily neutralize pathogens and help mark them for elimination by immune cells.
  2. How does IgG differ from other antibodies? IgG is the most abundant antibody in serum and has a unique ability to cross the placenta, providing immunity to fetuses.
  3. What role do IgG antibodies play in vaccines? IgG antibodies are often produced in response to vaccines, providing long-term protection against specific pathogens.
  4. Can IgG levels be tested? Yes, IgG levels can be measured through blood tests to assess immune function and detect certain infections.
