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

CD32 is a surface receptor protein and part of a large population of B cell co-receptors, which act to modulate signalling.

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.[1]

Monoclonal antibodies can distinguish between type A and type B.[2]
