... and antibody binding were assessed upon storage and after incubation with serum. M1- and M2-type macrophages were generated from blood monocytes to investigate RBC phagocytosis. Results: No complement deposition was directly observed on stored RBCs, while incubation of RBCs with serum resulted in variable...

... receptor-related protein-1 (LRP-1), but not scavenger receptors. The expression level and/or distribution of CD47 may be altered on the surface of apoptotic/senescent cells, rendering the phagocytosis inhibitory function of the CD47/SIRPα interaction reduced or eliminated. Instead, the interaction between...

... a conformational change in CD47. Intriguingly, erythrocyte phagocytosis after this switch seems to be mediated by the same receptor that normally signals inhibition of phagocytosis, SIRPα. In this review, the possible molecular mechanisms leading to this conformational change in CD47 as well as the possible signal...

... for plasma Na+ and K+, pH, LDH, lysozyme, PMN elastase, leukocytes, neutrophils, and neutro-phil phagocytosis with Phagotest®. Results: Leukocytes decreased from (5.0 ± 1.4) ×10 3 to (3.3 ± 1.3) ×10 3 cells/µl (mean ± SD), most of them being PMNs. Their phagocytic capacity when rewarmed did not change...
