Immune complexes
Immune Complexes
Immune complexes (pronunciation: /ɪˈmjuːn ˈkɒmpleksɪz/) are a crucial part of the immune system that help to protect the body from harmful substances.
Etymology
The term "immune complex" is derived from the Latin words "immunis" meaning exempt, and "complexus" meaning entwined. It refers to the entwined structure of the antigen and antibody that forms the immune complex.
Definition
Immune complexes are formed when antibodies bind to antigens to neutralize them. This process is a key part of the immune response, as it helps to remove foreign substances from the body.
Function
The primary function of immune complexes is to facilitate the removal of antigens from the body. When an antibody binds to an antigen, it forms an immune complex. This complex is then recognized by phagocytes, which engulf and destroy the complex, thereby removing the antigen from the body.
