Biological Function of IgG
Immune System
IgG bind to many typs of Microorganisms - Detrimental and provides protection against these Detrimental Microorganisms vis several mechanisms including:
Agglutination and immobilization
Compliment activation
Opsonization for phagocytosis
Neutralization of toxins produced by Detrimental Microorganisms
Antibody-dependent cell-mediated cytotoxicity(ADCC)
IgG permeates the body's tissues during Inflammation and stimulates Phagocytes to engulf Antigens.
Respiratory System
IgG helps to prevent recurrent Respiratory Tract Infections (patients with sub-optimal IgG levels generally experience recurrent Respiratory Tract Infections): [1]
Sub-optimal IgG levels may increase the severity of Influenza.
