Human cytomegalovirus (HCMV) causes gastro intestinal disease with ulcerations, apparently as a consequence of cytopathic damage to endothelial cells (EC) and subsequent microvascular obliteration. In this study we showed that cultured human intestinal microvascular endothelial cells (HIMEC) are much more susceptible to HCMV infection than human umbilical vein endothelial cells (HUVEC). When both cell types were challenged with a clinical isolate of HCMV (10 pfu per cell), 30% of HIMEC expressed HCMV immediate early proteins, but only 10% of HUVEC. Enhanced susceptibility was also reflected in the expression of early and late HCMV proteins. In addition, the interleukin-1beta (IL-1beta)-induced cellular expression of adhesion molecules differed between HIMEC and HUVEC after HCMV-infection. E-selectin was unaffected in HUVEC but increased in HIMEC, whereas vascular cell adhesion molecule (VCAM)-1 was increased in HUVEC but decreased in HIMEC. Furthermore, HCMV-infection enhanced the expression of intercellular adhesion molecule (ICAM)-1 in both cell types. In conclusion, the enhanced susceptibility to HCMV infection observed in HIMEC and the elevated expression of E-selectin and ICAM-1 observed in these cells may provide an indication to the liability of developing gastrointestinal HCMV disease and may have a possible relevance to the survival of intestinal transplants.
