Abstract

Factor XIII subunit A of blood coagulation (FXIII-A) is known to be synthesized but not secreted by the monocyte/macrophage cell line. On the basis of its intracellular localization and substrate profile, FXIII-A is thought to be involved in certain intracellular processes. Our present study was designed to monitor the changes in FXIII-A gene expression and protein production in long-term culture of human monocytes during their differentiation into macrophages in the presence of activating agents (interleukin-4, interferon-γ, Mycobacterium bovis BCG) inducing classical and alternative activation pathways. By using quantitative RT-PCR and fluorescent image analysis at the single-cell level we demonstrated that the expression of FXIII-A both at the mRNA as well as at the protein level is inversely regulated during the two activation programmes. Here we conclude that FXIII-A expression is an intracellular marker for alternatively activated macrophages, while its absence in monocyte-derived macrophages indicates their classically activated state.
