  • The effects of herpes simplex virus type 1 (HSV-1) infection on proteoglycan synthesis by human endothelial cells were studied as a model of endothelial cell injury. Confluent cultures of early passage endothelial cells from human umbilical vein were infected with HSV-1 at multiplicities of infection from 0.001 to 1.0. HSV-1 infection produced a dose-dependent inhibition of total proteoglycan synthesis of up to 85%. Although there was a 2- to 3-fold increase in the quantity of virus necessary to cause 50% inhibition of heparan sulfate compared to chondroitin/dermatan sulfate proteoglycan, the inhibition was relatively parallel, even up to high virus doses. There was no inhibition of an undersulfated heparan sulfate proteoglycan that contained glycosaminoglycan chains shorter than the predominant species. The results indicate that HSV-1 infection of human endothelial cells produces complex effects on host-cell metabolism. The viral-induced changes in proteoglycan metabolism may influence cell-matrix interactions and lead to altered vessel wall function.
