Abstract

With the aid of two-color immunofluorescence and flow cytometry, a new subset of cells coexpressing CD14 and CD16 antigens can be identified in human peripheral blood. Using the monoclonal antibody My4, these CD14+/CD16+ cells account for 2.2% of the mononuclear cells and form about 13% of all cells identified by the monocyte-specific CD14 monoclonal antibody. The CD14+/CD16+ cells can be assigned to the monocyte lineage based on typical morphology, on expression of additional monocyte-associated molecules, on the ability to form reactive oxygen intermediates and on the expression of monocyte- specific NaF-sensitive esterase. Light scatter analysis revealed lower forward angle and right angle light scatter for the CD14+/CD16+ cells compared with the regular monocytes, and the average cell size was determined to be 13.8 and 18.4 microns, respectively. Expression of class II antigens on these “small monocytes” was twofold higher compared with the regular monocytes. By contrast, the capacity to perform adherence to plastic surfaces, as well as the ability to phagocytize antibody-coated erythrocytes was clearly reduced in the CD14+/CD16+ monocyte subset as compared with the regular monocytes. Hence the CD14+/CD16+ cells appear to represent a new monocyte subset with a distinct functional repertoire. A survey of various tissues revealed that a large proportion of the alveolar macrophages, but not of the peritoneal macrophages, express the CD14+/CD16+ phenotype.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
