Impact of glabridin treatment on Toxoplasma gondii development in vitro and host cell viability. a Cytotoxicity of glabridin on Vero cells. Glabridin demonstrated low cytotoxicity in Vero cells. Cells were exposed to increasing concentrations of glabridin (0, 2.5, 5, 7.5, 10, and 20 µg/ml) for 24 h. Cell viability was measured using the Cell Counting Kit-8 (CCK-8) assay, with results expressed as a percentage relative to the untreated control group. Data represent the mean ± SD of three independent experiments. *P < 0.05; ****P < 0.0001. b Treatment with glabridin (5 μg/ml) significantly reduced the activity of extracellular T. gondii RH tachyzoites. ****P < 0.0001. c Inhibitory effect of glabridin (5 μg/ml) on the replication of intracellular T. gondii RH tachyzoites. Control samples (Ctrl) were collected 3 h post infection, while treatment groups were collected 48 h post infection, showing a marked decrease in parasite replication. ****P < 0.0001
