From Wikipedia, the free encyclopedia

This page is about "CD32" as a biological molecule. For the video game console please see Amiga CD32.

CD32 is a surface receptor protein found on B cells. It has a low-affinity for IgG antibodies and down-regulates antibody production in the presence of IgG. This feedback loops essentially lowers the production of IgG produced by B cells when there is a surplus in the body.
