Title: Serological characterization of human monocytes for HLA, B-lymphocyte, granulocyte, and monocyte-associated antigens by cytotoxicity testing. Author: Drew SI, Nathanson DS, Zamfirescu P, Carter BM, Terasaki PI, Naiem F, Billing R. Journal: Tissue Antigens; 1978 May; 11(5):385-93. PubMed ID: 308716. Abstract: Highly enriched preparations of monocytes, B and T lymphocytes, and granulocytes from 18 normal donors were serotyped in parallel in a complement-dependent cytotoxicity assay using allogeneic and heterologous antisera defining three independent tissue antigen systems. HLA and B-lymphocyte tissue antigens were detected on human monocytes although granulocyte antigens were absent. By cytotoxicity testing the presence of Ia-like antigens on monocytes was significantly diminished compared to the autologous B-lymphocyte population and has important implications in B-lymphocyte serology. The study indentified a number of human antisera obtained from multitransfused subjects and pre- and post-transplant organ recipients that were non-HLA and appeared to define monocyte-associated antigens. The serological implications of surface antigen expression on human monocytes compared with other peripheral blood cells are discussed.[Abstract] [Full Text] [Related] [New Search]
