Mammalian cells store excess fatty acids in the form of triglycerides within lipid droplets. The intracellular bacterium Orientia tsutsugamush is the causative agent of severe human rickettiosis. We found that O. tsutsugamushi infection induces the formation of lipid droplets in mouse L-929 fibroblasts. In infected cells, a parallel increase in the number of lipid droplets and pathogens was observed...
We screened for hepatitis C virus (HCV) inhibitors using the JFH-1 viral culture system and found that selective estrogen receptor modulators (SERMs), such as tamoxifen, clomifene, raloxifene, and other estrogen receptor α (ERα) antagonists, inhibited HCV infection. Treatment with SERMs for the first 2 h and treatment 2–24 h after viral inoculation reduced the production of HCV RNA. Treating persistently...
