The physiologic function of the monocyte transglutaminases is not known. In this study, we detected Factor XIII A-subunit antigen and "tissue" transglutaminase antigen in human monocytes by polyacrylamide gel electrophoresis and immunoblotting techniques. Flow cytometric analysis demonstrated that 27% and 49% of the total Factor XIII antigen in monocytes and human peritoneal macrophages, respectively, are expressed on the surface of the cells. Monocytes maintained in culture for 8 days had a 4-fold increase in Factor XIIIa activity and a 3.2-fold increase in the amount of Factor XIII antigen/mg cell protein. However, there was no increase in the "tissue" transglutaminase activity or antigen levels in cultured monocytes. In addition, we identified a Factor XIII deficient individual who does not express Factor XIII activity or antigen in plasma, platelets, monocytes, lymphocytes or erythrocytes. Intact monocytes from normal donors were able to cross-link fibrin formed in the plasma from the Factor XIII deficient individual. This suggests that transglutaminase activity expressed by peripheral blood monocytes may play a physiologic role in cross-linking fibrin during blood clotting or inflammation.
