| Outline of Final Research Achievements |
While Plasmodium is at the liver stages, clinically symptom is silent and do not cause obvious cytopathy to hepatocytes. We examined if Plasmodium proteins specifically expressed at the liver stages have potential to inhibit hepatitis C virus (HCV) replication and to reduce cytopathy of hepatocytes caused by HCV infection. P. falciparum circumsporozoite protein showed almost no cytotoxicity against control cells whose HCV subgenomic RNA replicon was eliminated by interferon-α treatment. Cell viability was reduced compared to control cells when circumsporozoite protein was transiently expressed in Huh7.5-derived cell lines harbouring an HCV subgenomic RNA replicon. Inflammatory cytokine IL-8 mRNA level was increased in circumsporozoite protein-expressing cells harbouring an HCV subgenomic RNA replicon. We concluded that P. falciparum circumsporozoite protein is one of the candidates as the anti-HCV drug.
