T174 0-223 Sentence denotes Most FcγRs (Table 2) are weak, low‐affinity receptors (affinities in the micromolar range) for IgG‐Fc, irrespective of whether the IgG is uncomplexed, monomeric or when it is complexed with antigen (i.e. an immune complex).
T175 224-465 Sentence denotes The very avid binding of immune complexes to an effector cell surface that displays an array of FcγR molecules is the result of the collective contributions of the low‐affinity interactions of each Fc of the IgGs in the complex with an FcγR.
T176 466-618 Sentence denotes This avidity effect is necessary as the FcγRs operate in vivo in environments of high concentrations of uncomplexed monomeric IgG (normally 3–12 g L–1).
T177 619-709 Sentence denotes Thus, the avid multivalent binding of the complex out competes uncomplexed, monomeric IgG.
T178 710-763 Sentence denotes The notable exception to this is the enigmatic FcγRI.
T179 764-940 Sentence denotes This receptor shows high, nanomolar affinity for uncomplexed monomeric IgG and thus would be expected to be constantly occupied in vivo by the normal circulating monomeric IgG.
T180 941-1008 Sentence denotes However, IgG dissociation permits engagement with immune complexes.
T181 1009-1175 Sentence denotes Furthermore, FcγRI is not expressed or expressed poorly on resting cells, requiring interferon‐γ for induction of its expression, presumably at sites of inflammation.
