PURPOSES: To understand the pathogenesis in rat corneal endothelial cells (RCECs) induced by murine cytomegalovirus infection in vitro and in vivo.
METHODS: In vitro, cultured RCECs were infected with murine cytomegalovirus strain K181-eGFP (MCMV-eGFP). In vivo, experimental rats received intracameral injection of MCMV-eGFP. Replicating viruses and morphology change of RCECs in vivo were evaluated at several time points.
RESULTS: In vitro, RCECs became necrosis at 6hpi. MCMV-eGFP began replicating at 12hpi. In vivo, the inflammatory reactions appeared at 12hpi, peaked at 72hpi and gradually subsided. Replicating MCMV-eGFP appeared in RCECs in vivo from 24hpi to 72hpi. RCECs enlarged after 12hpi and capsids in the nuclei were visible at 72hpi. A monocyte was found on a corneal endothelium at 120hpi.
CONCLUSIONS: RCECs were sensitive to MCMV in vitro. Replication of MCMV-eGFP in vivo began at 24hpi and ended after 72hpi, later than the inflammatory reactions.
