WebFcγRs is regulated by the affinity of the IgG Fc for the specific receptor and the expression pattern of those receptors on ef-fector cells (3). Because most effector cells coexpress activating and inhibitory FcγRs, the ratio of the binding affinities of a specific IgG Fc to these receptors determines the outcome of the IgG–FcγR interaction. Webspecific IgG Fc to these receptors determines the outcome of the IgG–FcγR interaction. Thus, IgG modifications that selectively enhance the affinity of IgG for activating FcγRs …
