Flow cytometric determination of circulating immune complexes with the indirect granulocyte phagocytosis test.
نویسندگان
چکیده
A method for the determination of circulating immune complexes (CIC) was adapted for flow cytometric analysis. Human granulocytes were used to phagocytose IgG-bearing CIC of serum from systemic lupus erythematosus (SLE) patients. A method for labeling the phagocytosed CIC with FITC-conjugated anti-human IgG was developed where the granulocytes remain in suspension during fixation and labeling. The fluorescence per cell, measured with a flow cytometer, is a measure of the total amount of the phagocytosed IgG. The results indicate that a rapid and quantitative method for the detection and measurement of phagocytosed CIC is possible using the flow cytometer.

Characterization of the Hemocytes in Larvae of Protaetia brevitarsis seulensis: Involvement of Granulocyte-Mediated Phagocytosis
Hemocytes are key players in the immune response against pathogens in insects. However, the hemocyte types and their functions in the white-spotted flower chafers, Protaetia brevitarsis seulensis (Kolbe), are not known. In this study, we used various microscopes, molecular probes, and flow cytometric analyses to characterize the hemocytes in P. brevitarsis seulensis. The circulating hemocytes w...

(1) The phagocytosis of human IgG, IgM, and C3 by granulocytes from various rheumatoid and nonrheumatoid sera and synovial fluids (SF) was investigated by direct examination of the patient's leucocytes and indirect testing by incubation of normal donor leucocytes with various sera and SF. (2) In rheumatoid arthritis (RA) phagocytosis of IgM, IgG, and C3 was common from sera and SF. There was a ...
متن کاملAn impaired phagocytic function is associated with leucocyte activation in the early stages of severe acute pancreatitis.
BACKGROUND An excessive leucocyte activation takes place early in severe acute pancreatitis. Furthermore, some indirect evidences suggest a disturbance of the mononuclear phagocytic system in the severe cases. AIMS To compare the early functionalism of leucocytes obtained from patients with mild disease and severe disease, under the hypothesis that an impaired phagocytic function could be ass...

A flow cytometric phagocytosis assay was established to investigate the role of anti-merozoite antibody, complement, and cytokines on the phagocytosis of Plasmodium falciparum merozoites by human neutrophils. This assay involved allowing fluorescein isothiocyanate-labeled merozoites to interact with phagocytes and analysis of the cells on a FACScan with Lysis II software. To differentiate the p...
