Abstract:
:Antigen-antibody complexes, composed of 125I-BSA and guinea-pig or rabbit antibody, were incubated at 37 degrees C with human blood cells suspended in autologous serum and kinetics of binding analysed. When purified polymorphonuclear (PMN) or mononuclear cells (MNC) were studied, maximum binding was observed within 8 min, and immune complexes (IC) remained associated with cells even after 1 hr. When cells were studied unseparated (in the same amount of serum), maximum binding was observed slightly earlier (within 4 min), but within 15 min most of the IC were found in the serum. Separation of cell types at the time of maximal binding and studies with cell preparations depleted of different elements revealed that binding was principally to red blood cells (RBC). IC recovered in the serum 16 min after addition to unseparated cells bound very slowly to purified PMN or MNC; binding after 30 min was 10-15% of that observed with fresh IC at 8 min. Ultracentrifugal analysis revealed that reduction in binding efficiency correlated with decrease in the size of IC. RBC isolated after binding and release of IC bound newly-formed IC was identical rapidity and capacity as fresh RBC, indicating that receptors were not altered by IC. Kinetics studies with serum in the absence of cells suggested that interaction with RBC accelerated the rate of change in binding properties of IC. Rates of binding and release were independent of antigen/antibody ratio but were slowed and binding to RBC sustained when diluted or hypocomplementaemic (SLE) serum was substituted for neat serum. Our results suggest that competition for IC by RBC is associated with loss of ability of IC to bind to other blood cell types and reduction in size of IC, and that abnormalities of complement can lead to prolonged association of IC with RBC.
