[Specific receptors for triiodothyronine in nuclei isolated from normal human polynuclear neutrophils].
In normal subjects, nuclei isolated and purified from circulating granulocytes bound 125I-T3. Binding was reversible and inhibited by unlabelled hormone. Scatchard plots showed a single class of high affinity sites (Kd: approximately 1,5 nM) with a high maximal binding capacity (MBC: approximately 400 fmol of T3 bound/100 micrograms of DNA). Structural analogs partially competed with 125I-T3 binding. These data suggest that human normal polymorphonuclear neutrophils possess specific nuclear receptors for triiodothyronine.
