RESUMO
Adhesion to endothelial cells by blood cells was assessed by measuring the cell number of each blood cell component in the supernatant after exposing blood cells to dengue-infected endothelial cells for 0, 10, 20 and 30 minutes. White blood cells, neutrophils, lymphocytes, platelets, and large lymphocytes or large unstained cells (LUC) preferentially bound to dengue-infected endothelial cells as compared to the control endothelial cells. P values were 0.0096 for total leukocytes and platelets, 0.006 for lymphocytes, and 0.001 for neutrophils and LUC. Monocytes basophils and eosinophils had no interaction with dengue-infected endothelial cells. The increased binding of neutrophil and platelet to endothelial cell may explain neutropenia and thrombocytopenia in DHF patients.
