The mechanism by which immune complexes deposit in vascular tissue is uncertain. Several human viruses, including herpes simplex virus, have recently been demonstrated to replicate in human endothelial cells. Such viruses may injure vascular tissue and could play a role in the pathogenesis of immune complex deposition. Therefore, we studied the expression of receptors for immune complexes containing IgG and C3 on endothelial cells after infection with herpes simplex virus type I.
Human umbilical vein endothelial cells were incubated with 51Cr-labeled sheep erythrocytes sensitized with IgG, IgM, or IgM plus complement. Preferential binding of IgG or complement-coated erythrocytes to uninfected endothelial monolayers was not observed. In contrast, significant binding of erythrocytes coated with IgG or IgM plus complement was observed after viral infection. Phase-contrast and scanning electron microscopy demonstrated erythrocyte adherence around the infected endothelial cells in a rosette pattern. Binding of IgG-coated erythrocytes was fully inhibited by Fc (0.31 mg/ml) but not Fab′ fragments of nonimmune IgG. Binding of complement-coated cells was unaffected by the presence of IgG (1 mg/ml). With purified individual components, binding of complement-coated erythrocytes depended on the presence and was proportional to the concentration of C3. Binding of IgG-or C3-coated cells was detected beginning 4 h after infection.
These studies indicate that herpes simplex virus type I infection can induce IgG and C3 receptors on human endothelial cells. These receptors may promote the deposition of immune complexes in vascular tissue after certain viral infections.
