TgROP18 functions in STAT3 phosphorylation in HaCaT cells during T. gondii infection. HaCaT were infected with indicated parasites and harvested. a Total proteins of HaCaT cells were loaded and activation of STAT3 was determined by western blot using anti-phospho-Stat3-Y705 and anti-phospho-Stat3-S727. b Densitometric quantitation of each band in A was applied using Image J. Statistical analysis was conducted with the Kruskal-Wallis H-test with Bonferroni correction (*P < 0.05, **P < 0.01 and ***P < 0.001). Error bars show the standard errors (SD)
