Specificity and affinity of human Fcγ receptors and their polymorphic variants for human IgG subclasses

Distinct genes encode 6 human receptors for IgG (hFcgammaRs), 3 of which have 2 or 3 polymorphic variants. The specificity and affinity of individual hFcgammaRs for the 4 human IgG subclasses is unknown. This information is critical for antibody-based immunotherapy which has been increasingly used i...
