Fig. 7From: Indole alkaloids inhibit zika and chikungunya virus infection in different cell linesAntiviral activity on the production of infectious viral particles from cultures of Vero cells treated with the combined strategy. A. Schematic representation of the combined-treatment strategy explained in the Materials and Methods section. B. Infection percentage calculated according to the results obtained by plaque assay (PFU/ml) of the supernatants collected from Vero cells infected with CHIKV/Col under each experimental condition. C. Infection percentage calculated according to the results obtained by plaque assay (PFU/ml) of the supernatants collected from Vero cells infected with ZIKV/Col under each experimental condition. The asterisks indicate statistically significant differences with respect to the control without compound (*p < 0.05, **p < 0.01 and ***p < 0.001; Student’s t-test), and error bars indicate the standard error of the mean; n: 4. Representative images of plaques formed under each experimental condition are shown (B and C)Back to article page
