Description
Description: IgG functions in the humoral immune response1. There are four subclasses of IgG, and they are numbered according to decreasing abundance as IgG1 through IgG4. While IgG4 is the least abundant of these subclasses, it is the predominant IgG involved in chronic or repeated antigen exposure, leading to an anti-inflammatory response. IgG4 is not usually part of the antibody response to bacterial or viral infection. Rather, it dominates the response to allergens and parasitic worm infections. IgG4 has unique properties relative to other IgG antibodies1. IgG4 affinity for Fc receptors and complement is relatively lower and IgG4 is largely unable to activate antibody-dependent- immune effector responses. IgG4 also performs Fab-arm exchange and is more highly glycosylated. Additionally, the IgG4 response is blocking in nature and able to induce tolerance and limit inflammation in the host, and particularly protects against allergic inflammation. IgG4 is produced by B cells that undergo class-switch recombination from IgM to IgG4 via T helper 2 cell responses1.
