Abstract
Sera from patients with rheumatoid arthritis inhibited the migration of human neutrophils in 63% (22 out of 35) of the cases tested. The inhibition was not due to a toxic effect of the serum, as it was reversed by a chemotactic stimulus. There was a strong correlation between the degree of inhibition of neutrophil migration and the amount of immune complexes present in the sera as determined by the C1q [q fragment of complement component 1] binding activity. The inhibition of neutrophil migration is apparently due to the presence of circulating immune complexes, and the capacity of immune complexes to inhibit neutrophil migration in vitro may also contribute to the accumulation of neutrophils at sites of immune complex formation in vivo.This publication has 17 references indexed in Scilit:
