BACKGROUND: One of the described mechanisms leading to thrombosis in antiphospholipid syndrome (APS) is overexpression of tissue factor (TF) in the monocytes and endothelial cells of patients with antiphospholipid antibodies (aPL). Vascular endothelial growth factor (VEGF) may stimulate monocyte TF expression through its receptor, the tyrosine kinase Flt-1. OBJECTIVES: This study aimed to analyze the following in monocytes of 55 primary APS patients: VEGF and Flt-1 expression levels, their potential regulation by aPL, and the association of VEGF and Flt-1 expression with the increased TF expression found in APS patients. RESULTS: Purified monocytes from APS patients showed higher levels of VEGF and Flt-1 than healthy donors, which further correlated with immunoglobulin G (IgG) anticardiolipin titers and TF expression rank. Moreover, monocyte VEGF and Flt-1 levels were significantly higher in patients with than in patients without previous thrombosis. In vitro, IgG from APS patients inc
