Assessment of the effect of curcumin on post-internalization and cell fusion in PRRSV-infected Marc-145 cells. Marc-145 cells were infected with GD-HD (MOI: 0.1) and subjected to a virus post-internalization assay. PRRSV N protein levels (a) and virus titers in cell supernatants (b) were detected using western blot and CCID50 assay, respectively. Each value represents the mean ± SD from three independent experiments (*, p < 0.05; **, p < 0.01; ***, p < 0.001; ND means non-detectable). For the observation of cell fusion, Marc-145 cells were subjected to the low pH-dependent cell fusion assay. Cell changes were observed under light microscope (c)
