G, hmCD40 mHEVc cells treated with or without CD154 were infected with either WT or MIC1-3 ko tachyzoites in the presence of complete medium (CM) alone or medium plus MIC3, MIC4, M2AP or MIC6 (all 10 nM). Parasite load was determined microscopically 24 h post challenge. Results shown are representative of 3-4 independent experiments.
