Characteristics of human mononuclear phagocytes.

TL;DR: The data suggest that PMN chemotactic function is resistant to the stress of uncomplicated major surgery in neonates and children.

TL;DR: These techniques for studying neutrophils and monocytes in skin abrasions and a simple assay of phagocytic and bactericidal function are suitable for inclusion in the early screening of individuals who have repeated bacterial infections.

TL;DR: The synergistic effect observed between T and Null cells is not due to the promotion of Null- cell proliferation by T -cell products but can be accounted for by diffusible Null-cell products enhancing the process of T lymphocyte activation by mitogens.

TL;DR: The morphological, cytochemical and functional characteristics of all these kinds of cells, as well as their proliferative behavior in vivo and in vitro, show great similarity, although there are also distinct differences.

TL;DR: Inclusion of cells in the "mononuclear phagocyte system" is based on similarities in the morphology, function, origin, and kinetics of the phagocytes, and reticular cells, dendritic cells, endothelial cells, and fibroblasts (fibrocytes) are excluded.

TL;DR: A method is described for demonstrating leukocyte peroxidase activity in which benzidine dihydrochloride is used as the indicator compound instead of the more commonly used but potentially more hazardous benzidine base.

TL;DR: Results indicate that attachment of a particle to specific receptors on the macrophage plasma membrane is not sufficient to trigger ingestion of that particle, and that ingestion requires the sequential, circumferential interaction of particle-bound ligands with specific plasma membrane receptors not involved in the initial attachment process.
